1. Conference Info 1.1 VEH 2019

Vibration energy harvesting is an interdisciplinary research area, which requires substantial synergy among very diverse expertise from both the academic and industrial communities. In 2018, a group of researchers who share the same particular interest in vibration and energy harvesting had set up a WeChat group for making a better connection and brainstorming on the related research topics. The 1st International Conference on Vibration and Energy Harvesting Applications (VEH 2018) was initiated by Prof. Fei from Southern University of Science and Technology, Prof. Junyi Cao from Xi’an Jiaotong University, and Prof. Wenming Zhang from Shanghai Jiao Tong University. It was held in the Southern University of Science and Technology, Shenzhen, China, during Nov. 2-4, 2018.

The 2nd International Conference on Vibration and Energy Harvesting Applications (VEH 2019) is held in another young and vibrant university in China, ShanghaiTech University. It aims to create an effective platform for both the domestic and global researchers, on which they can share the latest information on the development of the related technologies, have in-depth discussions, and build up friendships and collaborations across the disciplinary boundaries.

VEH 2019 is well received. As of July 1st, 2019, we have received over 70 paper submissions and over 100 registrations. The paper topics range from mechanical design and dynamics, power management circuits and systems, MEMS technology, and self-powered IoT applications, etc. Besides the participation of academic people, this year we have also attracted people from industry to join the event. We got some sponsorships from the academic organization (IEEE Industrial Electronic Society) as well as three companies from the related industries.

VEH 2019 will be carried out in a single session style for effective information sharing and discussions among experts from different disciplines. It has 6 Keynote Talks, 32 Oral Presentations, including 11 Invited Talks, and more than 40 Poster presentations.

Title: Broadband Energy Harvesting and Generation with Piezoelectric Transduction

Abstract: Piezoelectric transduction is highly attractive in miniature energy harvesters because of its simplicity, compatibility with micro-scale integration, and ability to provide high voltages even at low frequencies. However, because of the low electromechanical coupling coefficient of practical piezoelectric materials, these devices are usually incorporated in mechanically resonant structures to enhance power density, and this results in narrowband operation. This presentation will discuss methods to achieve broadband performance, and present recent results including frequency up-conversion devices based on magnetically plucked resonators. Advanced power processing circuits will be reviewed, and results presented to show the high suitability of plucked piezoelectric devices for power enhancing active switched circuits. The use of piezoelectrics in continuously rotating micro- generators will be discussed, and modeling will be presented to show their advantage over electromagnetic generators below the cm size scale.

Title: Progress and Applications of Energy Harvesting Technology

Abstract: In the past decade, significant growth in energy harvesting technology, which scavenges the wasted energy available in the ambient environment such as vibrations, heat, light, radiation, wind, water etc., and converts it into electrical energy, as a potential inexhaustible source for low-power devices. When the advanced CMOS technology migrates to 7nm scale, the availability of ultra-low-power integrated circuits (ICs) and MEMS sensors of 1 µW (or less) power consumption make the sensor nodes in the coming era of Internet-of-Things (IoT) become feasible to be operated by using the energy harvested from ambient environment. Considering the same dimension of chip-scale sensor nodes, micro energy harvesters, or microelectromechanical systems (MEMS) based energy harvesters (EHs), becomes a promising component for realization of self-sustained miniaturized IoT Sensor nodes. Although the MEMS EHs normally could not provide large output power, they remain as good alternatives of power supply for IoT sensor nodes. On the other hand, Z. L. Wang reports the triboelectric nanogenerator (TENG) in 2012. Various micro-/nano- systems enabled by the integration of triboelectric nanogenerators and flexible electronics technology are presented in this talk to show the feasibility of achieving "all-in-one" multi- functional self-sustained system.

Title: Vibration-based Energy Harvesting: Challenges, Solutions and Opportunities

Abstract: Transforming ambient energy that is otherwise wasted to electric power has evolved into an applied research field that aims at developing technologies to power electronic devices, circuits and wireless networks. Because semiconductors consume milliwatts (mW) in run operation mode and nanowatts (nW) in standby mode, energy harvesting of few mW is considered as an enabling technology that can be used to design self-powered sensors capable of monitoring and controlling a system’s performance, wirelessly transmitting and receiving data, and initiating decision making. A widely available and viable energy source is vibration with the common energy harvester consisting of a structure, transduction element and an electric load. Different aspects of vibration energy harvesters need to be addressed in order to increase their efficiency and power or energy density and implement them to support monitoring devices. Towards achieving that objective, we will discuss the exploitation of nonlinear phenomena to broaden the bandwidth of vibration energy harvesters and their use to support autonomous monitoring. We will present examples to show how such phenomena can be realized through simple variations of the harvesting structure along with examples of effective fluidic energy harvesting from aeroelastic vibrations. We will also discuss challenges and recent advances in the development of wireless ultrasonic vibration energy transmission as an approach to power sensors and devices. Particularly, we present patterning and focusing of the transmitted acoustic energy in space as an approach to simultaneously power distributed sensors or devices.

Liqun Chen

Professor Department of Mechanics Harbin Institute of Technology (Shenzhen), China

Title: Analysis on Vibratory Energy Harvesters via Harmonic Balance

Abstract: The idea of harmonic balance is implemented to analyze nonlinear vibrations of energy harvester systems. The resulting algebraic equations are numerically solved by the Newton–Raphson method with the help of the arc-length continuation technique. Both a traditional harmonic balance approach and an incremental harmonic balance approach are developed for vibratory energy harvester systems. The two approaches yield the same results. To handle complicated non-polynomial nonlinearities, an approach based on harmonic balance with the help of alternating frequency/time domain technique is proposed for strongly nonlinear vibration energy harvester systems. The proposed approaches are successfully implemented a nonlinear piezoelectric energy harvester with a magnetic oscillator and a Duffing type energy harvester with strong nonlinear electric terms. The harmonic balance solutions are well supported by numerical simulation results. The approaches are applied to a 1.5 degree-of-freedom model of an energy harvester based on a piezoelectric circular composite clamped with a proof mass on the plate. System identifications demonstrate strongly nonlinearities in the model. The experimental results validate the amplitude-frequency responses predicted by the proposed harmonic balance approaches, even in the case that there coexist hardening and softening characteristics under sufficiently large excitations.

Title: Vibration Energy Harvester with Linear Driven Rotor

Abstract: Recently, rotation kinetic energy has been harvested by electrostatic, piezoelectric and electromagnetic methods. In our daily life, however, linear movement is more popular than the rotational motion. In this presentation, we have demonstrated a new structure based on a linear driven rotor design. This structure could be used efficiently for energy harvesting from low frequency human motion, which could be applicable for both electrostatic and electromagnetic methods.

Title: A Tunable Wideband Piezoelectric Vibration Energy Harvester for Low-Frequency Environment Using a Novel Impact- and Rope-Driven Hybrid Mechanism

Abstract: Piezoelectric vibration energy harvester (PVEH) transforming vibration energy into electrical power has increasingly been attracting research interest in the recent years. For the real applications, most environmental vibrations occur at a low frequency range (normally below 100 Hz). Hence, the frequency up-conversion (FUC) technique, which can convert low frequency vibrations to high frequency oscillations, is widely used in PVEH. While environmental vibrations are usually variable, and sometimes it may be impossible to achieve a harvester with enough bandwidth to enable practical applications. In addition, owing to the fabrication error, the conventional impact-based FUC PVEH may not have the exact performance as that expected/designed. Thus, a method to conveniently adjust the working frequency of a wideband energy harvester without re-fabrication or damage to the original structure is desirable. In this talk, a tunable FUC wideband PVEH is proposed, which is developed by adopting a novel impact- and rope-driven hybrid mechanism. For the proposed PVEH, the desired performance can be achieved by adding the rope and controlling the rope length without any structure re-fabrication. Thus, this tunable device affords a promising means of working effectively in a variable and complicated low- frequency environment.

Title: “Micro” & “Macro” Vibration Energy Harvesters

Abstract: Energy harvesting has been demonstrated as an effective way to harvest vibrational energy to drive wireless electronic devices. There are many forms of vibrational energy in the natural world, such as wind, ocean wave and mechanical vibration. Our group has done some research about mechanism, materials and devices according to the characteristics of the vibration source, utilizing a variety of energy harvesters. We designed the piezoelectric harvester to gather the wind energy on the theory of flow flutter, also extended the method to the triboelectric generator, and achieved the transformation from “Micro” to “Macro”. Recently, we have presented a hybrid nano-generator in according to Bernoulli phenomenon, and make a breakthrough on accomplishing the couple of two thin films. Also, we designed several structures to assemble the wave power successfully. Furthermore, we also did the research of basic theory on materials, utilized the method of plasma and the properties of ferroelectric materials to increase the output power of the triboelectric nano-generator. In summary, these fundamental studies are the cornerstone of the development of energy harvesting technology.

Title: Standardization of Triboelectric Nanogenerators Progress and Perspectives

Abstract: The rapid development of the Internet of Things (IoT) and the increasing energy crisis call for a new type of energy source. Triboelectric nanogenerators (TENGs), which can convert mechanical energies to electricity, develop quickly in recent years and catch more and more people's attention all over the world. Meanwhile, the importance of the standardization for TENG has been emphasized, thus developing standardized theoretical models and experimental methods to quantitatively evaluate the performance becomes more and more important for the commercialization and industrialization of the TENG technology. This presentation will systematically review the origin of the V-Q plot (the standardized characterization tool) and the figure-of-merits (FOM, the standard for quantitatively charactering the energy output per cycle for TENG). Several essential factors which are going to be potentially involved in the standardization for TENGs will also be discussed, including the input energy, efficiency, environmental factors, and life-time assessment. At the same time, the studies about standards may open new research topics in this field. The standardization of TENG will be extremely helpful to understand and improve further applications of this emerging energy harvester. We believe that the standardization of TENG will greatly facilitate the commercialization and industrialization of TENGs in the future.

Title: Nonlinear Resonator Arrays for Energy Harvesting and Earthquake Mitigation

Abstract: Millions of earthquakes occur every year worldwide, which usually throw off a vast amount of vibrational energy at frequencies of 1-20 Hz and weaken or even collapse buildings and other infrastructure that are not resistant to large vibration. Metamaterials, which are usually made from assemblies of multiple control units, have been developed and provided a new way to protect new and/or existing buildings by deviating or trapping the propagation of surface seismic waves away from the structure. However, the energy produced by earthquakes is rarely directly absorbed and harvested. Besides, most of recent researches on earthquake mitigation carried out by employing resonant metamaterials are confined to a narrow frequency. This contrasts the requirements to protect buildings from an earthquake with a rather broader frequency. Building off our previously developed dual function resonator, the proposed nonlinear resonator arrays consist of a set of rectilinear oscillators and rotary oscillators focused on not only mitigating vibrations but also converting the vibrational energy into electricity. Taking the advantage of the nonlinearity we show that by creating arrays of the resonators and burying them under the soil surface, vibrations with a broader bandwidth can be turned into electricity.

Title: Fully Integrated Inductor-Less Flipping-Capacitor Rectifiers for Piezoelectric Energy Harvesting

Abstract: Piezoelectric energy harvesting is demanded by the rising market of Internet-of- Everything (IoE) in order to achieve system autonomy or even battery replacement. The conventional synchronized-switch harvesting on-inductor (SSHI) approach relies on bulky external inductors with high quality factor to enhance the extractable AC-DC electrical power limited by the inherent capacitance of the piezoelectric energy harvester. As the new generation IoE continuous push toward miniaturization and higher levels of integration, alternative solutions using on-chip capacitor arrays to replace bulky off-chip inductors are emerging. This presentation discusses the fundamental theory and various capacitor array architectures, including three phase flipping-capacitor rectifier (FCR), seven phase FCR and 21-phase split-phase FCR, to enhance the extractable power from the piezoelectric energy harvester. We will also show how these architectures are evolved, and how their performance is improved step by step.

The quiescent current consumption of the system is calibrated to be less than 15 µA (10 µA average current consumption for ZigBee). Multiple sensors in a network communicate with a powered hub unit intermittently while continuously harvesting and storing energy, maintaining always-on operation without external energy input. A robust packaging method is developed for easy installation and facile retrofitting in the relevant industry environment. The temperature information of the equipment is monitored for more than 1 month. We demonstrate that the self-powering wireless sensor node can be implemented in a generic industrial power plant equipment with minimal cost and effort while providing real-time temperature sensing and long-term, continuous monitoring.

Title: Bi-Directional (Reverse) Wireless Charging

Abstract: Bidirectional (reverse) wireless charging has been adopted recently by major mobile phone makers like Huawei and Samsung. In this talk, two reconfigurable wireless power transceivers, which reuse almost all of the hardware, will be briefly discussed. In particular, a novel cross-connected structure for the differential Class-D power amplifier in the transmitter mode is proposed for reducing the switching losses. Fabricated in 0.35µm standard CMOS process with 5V devices, over 78% battery-to-battery charging total efficiency and over 0.6A wireless charging current are demonstrated with two identical transceiver chips with printed coupling coils on board.

Title: System-Level Design and Optimization of High Efficiency, Low-Noise and Robust MHz WPT Systems

Abstract: Our work on system-level approaches for high performance megahertz (MHz) wireless power transfer (WPT) systems will be described. Operation in the MHz frequency band presents technical challenges due to possible increased power losses, strong nonlinearities of devices, and electromagnetic interference (EMI) problem. Both feedback-based active control and passive design were developed to improve the robustness of the MHz WPT system when the coil relative position and final load changed, the two major sources of uncertainty. The Class E topologies were particularly applied to improve efficiency and facilitate optimization-based designs. Finally, recent efforts on multiple-receiver MHz WPT systems will be mentioned such as design of a current-mode Class E PA, analysis and compensation of cross coupling, and decoupled load power distribution with a scalable number of receivers.

Title: Considerations on the Self-Powered Realization of the Synchronous Switching Circuits

Abstract: To increase the harvested power, many synchronous switching harvesting techniques were developed. For these synchronous switching circuits, the self-powered realization remains a hot topic. A variety of approaches have been studied, including electronic breakers, mechanical switches, velocity control or integrated circuits etc. In the self-powered switching circuits, the switches automatically take actions to invert the piezoelectric voltage based on the information from the peak detectors that the maxima or minima are attained. Therefore, the harvested power is strongly related to the available open-circuit voltage magnitude and the phase lag between the switching actions and the corresponding piezoelectric extrema in the self-powered circuits. Previous studies mainly concerned the phase lag induced by the diode and the transistor in the electronic breaker. However, the envelope resistor and capacitor’s influence are not well analyzed in existed models. In this paper, comprehensive modeling and analysis taking these two factors into consideration are proposed. Investigations show that, the envelope resistor and capacitance affect the switching phase delay and the generator’s open-circuit voltage while considerable additional phase lag is introduced for charging the switch’s parasitic capacitance to turn on the switch.

Title: Flexible Three-Dimensional Interconnected Piezoelectric Ceramic Foam Based Composites for Highly Efficient Concurrent Mechanical and Thermal Energy Harvesting

Abstract: Flexible piezoelectric materials are pivotal to a variety of emerging applications ranging from wearable electronic devices, sensors to biomedical devices. Current ceramic- polymer composites with embedded low-dimensional ceramic fillers, though mechanically flexible, suffer from low piezoelectricity owing to the poor load-transfer efficiency that typically scales with the stiffness ratio of the polymer matrix to the ceramic fillers. Herein we introduce the scalable ceramic-polymer composites based on three-dimensional (3-D) interconnected piezoelectric microfoams. Comprehensive mechanics analyses reveal that the 3-D interconnected architecture presents a continuous pathway for load transfer to break the load-transfer scaling law seen in the conventional composites with low- dimensional ceramic fillers. The 3-D composite exhibits exceptional piezoelectric characteristics under multiple loading conditions (i.e., compression, stretching, and bending) and high mechanical durability under thousands of cycles. It also has excellent pyroelectricity, thereby enabling concurrent thermal and mechanical energy scavenging. Our findings suggest an innovative material framework for high-performance energy harvesters and self-powered micromechanical devices.
