Abstract :
Backscattering-based RFID-inspired communication provides an effective approach for wireless power and data transfer for implantable battery-free brain machine interface microsystems. We compare conventional and segmented transmit loop configurations to reduce the specific absorption rate (SAR) into human body. Moreover, we present novel cubic-millimeter implant antennas and link performance comparisons in terms of both power and voltage delivery to the implant.
