Abstract:The safety of powersupply for biomedical implants is critical in an implantable system.In this paper, an adaptive feedback with pulse width modulation (PWM) and load shift keying (LSK) is introduced and used in the design of a wireless power tra nsmission system. Experimental results show that the system can receive stable power wh en the distance bet\Wen the transmitter and receiver changes. Compared to the system without adaptive feedback, the efficiency is improved by 5.7times with the dis tance unde r 20mm… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
