PROJECT TITLE :

Characterization of Two-Turns External Loop Antenna With Magnetic Core for Efficient Wireless Powering of Cortical Implants

ABSTRACT:

We present a two-turns loop antenna with a magnetic core to transfer power wirelessly to a miniature cubic loop antenna in an exceedingly cortical implant. Compared to a same-sized single-flip loop antenna, it achieves reduction in the specific absorption rate (SAR) and transmits 20 mW (11%) a lot of power to the implant by maintaining the identical link power potency. We also investigate the optimum distance of the external antenna from the body in terms of the link power potency and SAR. Moreover, we have a tendency to gift a brand new technique of estimating the worst-case voltage amplitude incident at the front end of the implanted microsystem underneath totally different impedance matching conditions. We tend to have fabricated the straightforward and two-turns loop antennas and attested the link power potency of each in a very liquid phantom mimicking the dielectric properties of the human skin at one hundred MHz.
