Modeling and optimization of printed spiral coils in air, saline, and muscle tissue environments.

IEEE transactions on biomedical circuits and systems

Uei-Ming Jow, Ghovanloo M.
PMID: 20948991
IEEE Trans Biomed Circuits Syst. 2009 Oct;3(5):339-47. doi: 10.1109/TBCAS.2009.2025366. Epub 2009 Aug 25.

Printed spiral coils (PSCs) are viable candidates for near-field wireless power transmission to the next generation of high-performance neuroprosthetic devices with extreme size constraints, which will target intraocular and intracranial spaces. Optimizing the PSC geometries to maximize the power...

An Integrated Power-Efficient Active Rectifier With Offset-Controlled High Speed Comparators for Inductively Powered Applications.

IEEE transactions on circuits and systems. I, Regular papers : a publication of the IEEE Circuits and Systems Society

IEEE Trans Circuits Syst I Regul Pap. 2011;58(8):1749-1760. doi: 10.1109/TCSI.2010.2103172.

We present an active full-wave rectifier with offset-controlled high speed comparators in standard CMOS that provides high power conversion efficiency (PCE) in high frequency (HF) range for inductively powered devices. This rectifier provides much lower dropout voltage and far...

An RFID-Based Closed-Loop Wireless Power Transmission System for Biomedical Applications.

IEEE transactions on circuits and systems. II, Express briefs : a publication of the IEEE Circuits and Systems Society

Kiani M, Ghovanloo M.
PMID: 21179391
IEEE Trans Circuits Syst II Express Briefs. 2010 Apr 01;57(4):260-264. doi: 10.1109/TCSII.2010.2043470.

This brief presents a standalone closed-loop wireless power transmission system that is built around a commercial off-the-shelf (COTS) radio-frequency identification (RFID) reader (TRF7960) operating at 13.56 MHz. It can be used for inductively powering implantable biomedical devices in a...

Design and Optimization of a 3-Coil Inductive Link for Efficient Wireless Power Transmission.

IEEE transactions on biomedical circuits and systems

Kiani M, Jow UM, Ghovanloo M.
PMID: 21922034
IEEE Trans Biomed Circuits Syst. 2011 Jul 14;99:1. doi: 10.1109/TBCAS.2011.2158431.

Inductive power transmission is widely used to energize implantable microelectronic devices (IMDs), recharge batteries, and energy harvesters. Power transfer efficiency (PTE) and power delivered to the load (PDL) are two key parameters in wireless links, which affect the energy...
