Wireless Power Transmission With Self-Regulated Output Voltage for Biomedical Implant Abstract: This paper presents a wireless power transfer WPT system for powering implantable biomedical devices; the system is configured to achieve high efficiency even with CMOS switches and printed-circuit-board pattern coils and to maintain constant output voltage against coupling and loading variations without any additional blocks.

It is shown that the parallel-resonant transmitter TX and receiver RX topology is advantageous for high efficiency even with lossy but compact components. A parallel-resonant class-D oscillator TX is developed to track the optimum operating frequency for the constant output voltage.

The operating distance for the constant output voltage is also extended using a novel resonator structure, which contains two resonating coils. These proposed schemes allow a compact, efficient, and robust wireless power system.

Article :. Date of Publication: 16 July DOI: Need Help?Wireless power transfer WPTwireless power transmissionwireless energy transmission WETor electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, a transmitter device, driven by electric power from a power sourcegenerates a time-varying electromagnetic fieldwhich transmits power across space to a receiver device, which extracts power from the field and supplies it to an electrical load.

The technology of wireless power transmission can eliminate the use of the wires and batteries, thus increasing the mobility, convenience, and safety of an electronic device for all users. Wireless power techniques mainly fall into two categories, near field and far-field. In near field or non-radiative techniques, power is transferred over short distances by magnetic fields using inductive coupling between coils of wireor by electric fields using capacitive coupling between metal electrodes.

In far-field or radiative techniques, also called power beamingpower is transferred by beams of electromagnetic radiationlike microwaves [8] or laser beams. These techniques can transport energy longer distances but must be aimed at the receiver. Proposed applications for this type are solar power satellitesand wireless powered drone aircraft. An important issue associated with all wireless power systems is limiting the exposure of people and other living things to potentially injurious electromagnetic fields.

Wireless power transfer is a generic term for a number of different technologies for transmitting energy by means of electromagnetic fields. In general a wireless power system consists of a "transmitter" device connected to a source of power such as a mains power line, which converts the power to a time-varying electromagnetic field, and one or more "receiver" devices which receive the power and convert it back to DC or AC electric current which is used by an electrical load.

The word "antenna" is used loosely here; it may be a coil of wire which generates a magnetic fielda metal plate which generates an electric fieldan antenna which radiates radio waves, or a laser which generates light. A similar antenna or coupling device at the receiver converts the oscillating fields to an electric current. An important parameter that determines the type of waves is the frequencywhich determines the wavelength. Wireless power uses the same fields and waves as wireless communication devices like radio[18] [19] another familiar technology that involves electrical energy transmitted without wires by electromagnetic fields, used in cellphonesradio and television broadcastingand WiFi.

In radio communication the goal is the transmission of information, so the amount of power reaching the receiver is not so important, as long as it is sufficient that the information can be received intelligibly. In contrast, with wireless power transfer the amount of energy received is the important thing, so the efficiency fraction of transmitted energy that is received is the more significant parameter. Wireless power transfer may be used to power up wireless information transmitters or receivers.

This type of communication is known as wireless powered communication WPC. When the harvested power is used to supply the power of wireless information transmitters, the network is known as Simultaneous Wireless Information and Power Transfer SWIPT ; [20] whereas when it is used to supply the power of wireless information receivers, it is known as a Wireless Powered Communication Network WPCN.

These are the different wireless power technologies: [14] [17] [24] [25] [26]. Electric and magnetic fields are created by charged particles in matter such as electrons. A stationary charge creates an electrostatic field in the space around it. A steady current of charges direct currentDC creates a static magnetic field around it. The above fields contain energybut cannot carry power because they are static.This paper describes the integration of an active locomotion module in a wirelessly powered endoscopic capsule.

The device is a submersible capsule optimized to operate in a fluid environment in a liquiddistended stomach. A 3D inductive link is used to supply up to mWto the embedded electronics and a set of 4 radio-controlled motor propellers. The design takes advantage of a ferrite-core in the receiving coil-set. This approach significantly improves the coupling with the external field source with respect to earlier work by the group. It doubles the power that can be received with a coreless coil-set under identical external conditions.

The upper limit of the received power was achieved complying with the strict regulations for safe exposure of biological tissue to variable magnetic fields. An optimized locomotion strategy was defined which limits the power consumption by running only 2 motors at a time. A user interface and a joystick controller allow to fully drive the capsule in an intuitive manner. The device functionalities were successfully tested in a dry and a wet environment in a laboratory set-up.

Suggested articles.When compared to the existing WPT systems such as those based on the Qi low power specification of the Wireless Power Consortium, the main differences of the technical implementation for better applicability to glass laminate applications are a novel self-regulating antenna tuning solution and relatively high 6.

The self-regulating antenna tuning solution keeps the receiver output voltage nearly stable and maintains high efficiency by keeping the antennas in resonance with variable loading of the power receiver. The safety of the WPT system to nearby humans and electrical devices is ensured by ferrite shielding of the antenna coupler. The performance of the WPT system has been evaluated by theoretical analysis, circuit simulations and a preliminary experimental system.

The progress in material and manufacturing technologies has enabled the implementation of electronics with completely new features. In addition to the rigid silicon based electronics, flexible, deformable and large area electronics has become a reality.

As a part of this technological development, glass laminated electronics has become an interesting enabler for the products relevant to the fields such as architecture and automotive. Printed hybrid electronics integration inside glass laminates utilizes the latest knowhow of materials and manufacturing technologies. In this approach, the electronics is not only covered by glass, but it is embedded as a solid functional system within the glass laminate, resulting in different implementations from the conventionally glass protected devices such as solar panels or displays.

Already demonstrated functionalities include lighting, displays, sensing and wireless communication, all wirelessly powered through the glass laminates to facilitate environmental shielding of the embedded functionalities against dust, moisture and chemical contamination. Lighting, sensors and electronics targeted to be integrated in laminated glass structures are also introduced in [1], [2] and [3]. However, publications introducing wireless power transfer WPT capable of supplying high power for mentioned functionalities are lacking.

In this paper, we introduce a safe, high efficiency, small size WPT system with extremely thin power receiver capable of supplying up to 30W electric DC power for lighting, display, sensing and communication functionalities. Among the requirements of the wireless powering, safety to nearby humans is considered as number one. The system has also be safe to nearby devices, i. High efficiency is required in order to save energy and to avoid excess heating of the system that may increase the failure rate.

Small size is important to avoid degrading of the visual appearance, and extremely thin structure 1 mm or less is necessary to enable the integration into thin laminated glass systems. Figure 1 presents a generic physical level model of a WPT system based on inductive near field coupling. The right side of the diagram represents the wireless power receiver. The left side of the diagram is the wireless RF power transmitter that involves an RF inverter for generating RF power from DC supply power, and an antenna tuning network for matching the RF inverter with the effective complex load impedance of the antenna coupler.

The right side of the diagram is the wireless RF power receiver that involves a DC load for modelling the power extraction to the target application to be powered, an RF rectifier for generating DC power from the received RF power, and an antenna tuning network for matching the antenna coupler with the effective complex load impedance of the receiver.The homemade ice creams and eateries like a barn restaurant were very good and thoroughly enjoyable.
