A Flexible Solution-Processed Memristor
This article has been accepted for inclusion in a future issue of this journal. Content is final as presented, with the exception of pagination. IEEE ELECTRON DEVICE LETTERS 1 A Flexible Solution-Processed Memristor Nadine Gergel-Hackett, Member, IEEE, Behrang Hamadani, Barbara Dunlap, John Suehle, Senior Member, IEEE, Curt Richter, Senior Member, IEEE, Christina Hacker, and David Gundlach, Member, IEEE Abstract—A rewriteable low-power operation nonvolatile physi- cally flexible memristor device is demonstrated. The active compo- nent of the device is inexpensively fabricated at room temperature by spinning a TiO2 sol gel on a commercially available polymer sheet. The device exhibits memory behavior consistent with a memristor, demonstrates an on/off ratio greater than 10 000 : 1, is nonvolatile for over 1.2 × 106 s, requires less than 10 V, and is still operational after being physically flexed more than 4000 times.

The project aims to utilise object detection algorithms and visual data to analyse complex road scenes. The aim of this thesis is to determine the best tool to use to label data for training artificial intelligence algorithms, to specify what data should be saved and to determine what database is to be used to save the data. The validity of the findings is proved by building a small prototype to showcase integration between the labelling tool and the database.

Open Source Computer Vision-Based Layer-Wise 3D Printing Analysis
Open Source Computer Vision-based Layer-wise 3D Printing Analysis Aliaksei L. Petsiuk1 and Joshua M. Pearce1,2,3 1Department of Electrical & Computer Engineering, Michigan Technological University, Houghton, MI 49931, USA 2Department of Material Science & Engineering, Michigan Technological University, Houghton, MI 49931, USA 3Department of Electronics and Nanoengineering, School of Electrical Engineering, Aalto University, Espoo, FI-00076, Finland [email protected], [email protected] Graphical Abstract Highlights • Developed a visual servoing platform using a monocular multistage image segmentation • Presented algorithm prevents critical failures during additive manufacturing • The developed system allows tracking printing errors on the interior and exterior Abstract The paper describes an open source computer vision-based hardware structure and software algorithm, which analyzes layer-wise the 3-D printing processes, tracks printing errors, and generates appropriate printer actions to improve reliability. This approach is built upon multiple- stage monocular image examination, which allows monitoring both the external shape of the printed object and internal structure of its layers. Starting with the side-view height validation, the developed program analyzes the virtual top view for outer shell contour correspondence using the multi-template matching and iterative closest point algorithms, as well as inner layer texture quality clustering the spatial-frequency filter responses with Gaussian mixture models and segmenting structural anomalies with the agglomerative hierarchical clustering algorithm. This allows evaluation of both global and local parameters of the printing modes. The experimentally- verified analysis time per layer is less than one minute, which can be considered a quasi-real-time process for large prints. The systems can work as an intelligent printing suspension tool designed to save time and material. -

3164 IEEE SENSORS JOURNAL, VOL. 15, NO. 6, JUNE 2015 Technologies for Printing Sensors and Electronics Over Large Flexible Substrates: A Review Saleem Khan, Leandro Lorenzelli, Member, IEEE, and Ravinder S. Dahiya, Senior Member, IEEE Abstract— Printing sensors and electronics over flexible substrates are an area of significant interest due to low-cost fab- rication and possibility of obtaining multifunctional electronics over large areas. Over the years, a number of printing technolo- gies have been developed to pattern a wide range of electronic materials on diverse substrates. As further expansion of printed technologies is expected in future for sensors and electronics, it is opportune to review the common features, the complementarities, and the challenges associated with various printing technologies. This paper presents a comprehensive review of various printing technologies, commonly used substrates and electronic materials. Various solution/dry printing and contact/noncontact printing technologies have been assessed on the basis of technological, materials, and process-related developments in the field. Fig. 1. The classification of common printing technologies. Critical challenges in various printing techniques and potential research directions have been highlighted.

The pressure sensing is achieved by incorporating a quantum tunnelling composite material composed of graphite nanoparticles in a rubber matrix into the multilayer nanostructure of a printed organic thin film transistor. This printed device was able to convert shock wave inputs rapidly and reproducibly into an inherently amplified electronic output signal. Variation of the organic ink material, solvents, and printing speeds were shown to modulate the multilayer nanostructure of the organic semiconducting and dielectric layers, enabling tuneable optimisation of the transistor response. The optimised printed device exhibits Citation: Griffith, M.J.; Cooling, rapid switching from a non-conductive to a conductive state upon application of low pressures whilst N.A.; Elkington, D.C.; Wasson, M.; operating at very low source-drain voltages (0–5 V), a feature that is often required in applications Zhou, X.; Belcher, W.J.; Dastoor, P.C.
