Inductive Resonant Coils for Biomedical Wireless Power Transmission
2020 IEEE Wireless Power Transfer Conference (WPTC), 2020This study analyzes wireless transmission efficiency in magnetic resonance topology. In wireless power transmission systems, the overall efficiency is limited by the power consumption of coils. To improve the efficiency of wireless power transmission systems, this study proposes a suitable design for implantable devices by studying the shapes of coils,

Induction in Power Transmission Lines During Geomagnetic Disturbances
Space Science Reviews, 1980The electric field associated with geomagnetic disturbances gives rise to potential differences at the Earth's surface. Thus, currents are induced in power transmission lines which are earthed at both ends through transformers. The currents vary so slowly with time that they can be considered direct currents.

Power-oscillator based high efficiency inductive power-link for transcutaneous power transmission
2010 53rd IEEE International Midwest Symposium on Circuits and Systems, 2010Transcutaneous power transmission is a critical issue for long term reliable operation of implantable systems. This paper reports a power-oscillator based inductive power link to power up any implantable unit inside the human body. Instead of using power amplifier which requires high drive requirement, two power-oscillator based inductive powering ...

Inductive power transmission for untethered micro-robots
31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005A new concept for inductive power transmission is proposed to transmit constant power over a large area of interest. This concept includes a specially designed winding group at the power transmitting side, which is similar to the windings in a linear motor. The winding group generates a traveling magnetic field over the complete working area.

High power nonlinear transmission lines with nonlinear inductance
2010 IEEE International Power Modulator and High Voltage Conference, 2010Nonlinear transmission lines have been demonstrated to be an effective technique for generating high power ultrawideband or mesoband radiation without the need for a vacuum system, electron beam, or magnet. Experiments have been performed at UM on a discrete element nonlinear transmission line using nonlinear inductance with input powers of 100 MW ...

Bidirectional high data rate transmission interface for inductively powered devices
CCECE 2003 - Canadian Conference on Electrical and Computer Engineering. Toward a Caring and Humane Technology (Cat. No.03CH37436), 2004High data transfer rates in the order of 1 Mbit/s are now in demand for some inductively powered devices, but communication needs to be made without compromising power transfer and its efficiency. This paper compares different modulation schemes and proposes an interface to satisfy demanding bidirectional transmission needs. New demodulation approaches
