Abstract:
Existing single-link wireless power and data transfer (WPDT) systems for implantable biosensors support either closed-loop power regulation or sensor data uplink, but not both simultaneously, resulting in degraded efficiency and restricted sensing. This work presents a 13.56-MHz WPDT system with: 1) a synchronized phase-shifted time-multiplexed uplink scheme enabling TX power regulation …
