also for medical machines. Today the charge contacts are worn out by very aggressive disinfection agents. If completely encapsulated, these devices can be sterilized and using wireless energy transfer poses no major challenges for the casing technology, because open contacts are no longer necessary.

In the industrial area, wireless energy supplies offer the solution for many problems that occur today in devices with charging contacts in dirty, dusty or explosion-prone environments. This increases not only the reliability and robustness of industrial applications, but also their durability and thereby maintenance costs will be reduced. Wireless energy transfer can be used in driverless transport systems, suspension tracks, cranes, conveyor systems or for supplying sensors and actuators in pressure containers and tanks.

If helmet lamps and gas detectors have integrated wireless charge technology, this Wireless Power Transfer can prevent contact sparks in mining, refineries and chemical production. New challenges, but also new opportunities Wireless energy transfer works very well under water and can be used with diving By Cem Som / Jörg Hantschel robots, diving torches and underwater cameras. This is very important for the water tightness at great depths because the casings can be completely enclosed. 1. Introduction The way consumers use smartphones has changed significantly in recent years. This 3. Transmission paths for wireless power transfer applies not only to all mobile devices but also to all electric appliances in industrial There are a variety of methods by which energy can be transferred in a contactless and medical technology with and without batteries. Ever longer usage times and manner. The field of wireless power transfer can be divided into several technologies higher power demands of the end devices either increase the demand for compact and categories, depending on different factors such as, for example, the distance from and high-capacity batteries or the need to charge the devices wirelessly throughout the transmission source and modifications of the electromagnetic field. the day, which would mean the device needs to be integrated with the right wireless Wireless Power Transfer charging technology. To be successful, wireless charging must be simple and convenient to handle for the user and have a charge performance (charge time, efficiency, ...) that is comparable Near Field Far Field to conventional wire technology.

2. Application examples Electromagnetic Electromagnetic Induction Radiation Once the technology which is driven by consumer products (5–15 W), is established, many kinds of applications over a wide range of industries will follow. We believe it will be possible to charge a variety of devices in the area of mobile communications Electrodynamic Electrostatic technology (smartphones, tablets, digital cameras, fitness trackers, smart watches, Induction Induction baby phones etc.) using a single charging device. Nowadays this can’t be done because of all the different connectors, so wireless transmission of energy is a gain in convenience and mobility for our customers. Microwave Magnetic Magnetic Laser Power Power Induction Resonance Beaming We’re already transmitting energy wirelessly to charge batteries e.g. in electrical Transmission toothbrushes, beard trimmers, and electric razors. New applications, such as for Fig. 1 hairdryers or styling irons, would be possible and would avoid annoying cords and therefore increase the safety significantly. 3.1 Near-field technology In our kitchens we could use different appliances (power class 200 W – 2.4 kW) via Wireless near-field power transfer can transmit energy over a distance measuring one wireless energy transmission. Applications such as rice cookers, water boilers, or several external diameters of the transmission coil or shorter than one wavelength breadmakers, mixers, egg boilers and frying pans can be operated directly without (λ). Near-field energy is a non-radiative power-transmission technique, but radiation having a chargeable battery as energy supply. losses may still occur. In the normal case, only ohmic losses occur.

In medical technology, wireless energy transfer is used to supply energy to implants Near-field technology is subdivided into the following categories: and wireless endoscopes, for biomonitoring (heart frequency, EKG, temperature, blood 77 Electromagnetic induction pressure, neural activity), blood composition (oxygen saturation, blood glucose, carbon 77 Electromagnetic resonance dioxide, pH values), stimulation (pacemakers, muscle stimulation, neurostimulators), 77 Electrostatic induction monitoring and adjustment (activity, bladder pressure, implanted insuline pumps) and

3.1.1 Electromagnetic induction 3.2.1 Microwave power transmission Wireless power transfer by means of electromagnetic induction in the near field is The technique behind microwave power transmission involves the conversion of transmitted at an in-terval of 1/6 of the wavelength of the transmission frequency. In a energy into microwaves and the transmission of the waves to a rectifier and an current-carrying straight conductor, the magnetic field strength H and the static antenna (together a “rectenna”). The transmitted microwaves are then converted by magnetic field B are created around this conductor. When the wire is twisted to form a the receiver into conventional electricity. coil, this amplifies the magnetic field, which thus takes the form of a magnetic rod around the coil with a north and a south pole. The following steps are necessary: 77 Conversion of the electricity into microwave form by means of a magnetron According to Ampere’s law, the magnetic flux around the coil is directly proportional to 77 Reception of the microwave energy by means of a rectenna the current flowing through the coil. The magnetic field strength of a coil is defined by 77 Conversion of the microwave energy into electricity the flux. The more windings the coil has, the greater the magnetic field around the coil. William C. Brown, a pioneer in the area of wireless power transfer, designed and developed a system that demonstrated how energy can be transmitted through free It is also possible to remove the electric current and instead to position a permanent space in the form of microwaves. magnet within the coil. The mechanical movement of the permanent magnet and thus of the magnetic field induces a current in the coil. A current can also be induced when 3.2.2 Laser radiation the coil is moved over the permanent magnet (oscillation). In this way, the movement Laser radiation is the wireless transmission of energy (heat or electricity) from of the coil or the modification of the magnetic field can be used to induce voltage and transmitter to receiver with laser beams. The harvesting of solar power makes use of current. This process is named electromagnetic induction, which constitutes the basic the same transmission technique, in which the sunbeams hit photovoltaic cells and principle of a transmitter. convert the sunlight into energy. A special photovoltaic cell converts the laser beams into energy. Laser beams are far stronger than sunbeams, can be directly pointed at When the distance between two coils is too great, the total primary magnetic current target receivers with exceptionally high accuracy, and deliver energy 24 hours a day. does not flow through the secondary coil, which leads to a poor coupling and a This form of power can be transmitted through the atmosphere, through space, or leakage inductance. Leakage inductance is always present in a coupled coil system, through optical fibers. since the magnetic coupling of two coils is never perfect. The advantages of laser radiation: 3.1.2 Electromagnetic resonance 77 The close collimation of the beams enables energy to be transmitted in highly When the coupling between two galvanic isolated coils is poor, this results in leakage concentrated form over great distances inductance. One of the reasons for a poor efficiency between two coils is secondary 77 The receivers are very compact and can be easily integrated into available devices leakage inductance, which is much greater than the load used on the secondary coil. 77 The power can be transmitted without interfering with high-frequency communica- This leakage inductance makes it necessary to generate a large inducted voltage in tion systems (e.g. WiFi or LTE) the secondary circuit. Applying a larger current on the primary coil results in a greater 77 Laser radiation can use all existing sources of energy for the laser induced voltage on the secondary side, thus creating even greater losses. This is why 77 Energy can be transmitted through free space or by optical-fiber networks it is conventional practice in inductive couplings to eliminate the secondary leakage inductance by using a capacitance. The drawbacks of laser radiation: 77 Poor efficiency 3.1.3 Electrostatic induction 77 Transmitter and receiver must have a direct line of sight Electrostatic induction is a method for the wireless transfer of power between 77 The efficiency of the system is susceptible to atmospheric conditions electrodes of a capacitance. A high-frequency alternating voltage is generated on the plates of a capacitance that are positioned close to each other. This generates an 4. The dominating standards electric field, resulting in a current displacement, in turn making the electric field the The success of these solutions of course depends on maintaining a standard for power source. The power transmission is proportional to the distance between the transmitters and receivers. Only if there is assurance that the device can be charged plates. hassle-free at any charging station that meets the standard, regardless of the manufacturer, the system will be successful. What kinds of standard approaches are 3.2 Far-field technology out there and what’s the technology behind them? Far-field technology enables power to be transferred over relatively large distances, in many cases even over ranges of several kilometers. This distances are larger than the 4.1 Wireless Power Consortium (WPC) – Qi Standard external diameter of the coils used.

The following wireless power-transfer techniques are available for the far-field sector: 77 Microwave power transmission 77 Laser beam
