Abstract :
We analyze a two-turns antenna to provide power wirelessly to 2×2×2 mm3 cubic cortical implant. We present simulation of available power and voltage to the implant and assess the impact of a inserting a magnetic core in the antennas for further performance enhancement. We have fabricated the studied antennas and verified the simulated link power efficiency through measurement in a liquid phantom.
