An Efficient Wireless Power and Data Transfer System with Current-Modulated Energy-Reuse Back Telemetry and Energy-Adaptive Dual-Input Voltage Regulation

Implantable medical devices (IMDs) for bio-signal sensing and stimulation consume power from micro to milli-watt levels, while requiring continuous data telemetry through uplink and downlink. An inductive link with coupled coils can be a promising solution for efficient near-field wireless power tra...

Description
Summary:Implantable medical devices (IMDs) for bio-signal sensing and stimulation consume power from micro to milli-watt levels, while requiring continuous data telemetry through uplink and downlink. An inductive link with coupled coils can be a promising solution for efficient near-field wireless power transfer as well as bidirectional data telemetry through the power link without additional coil/antenna. The wireless power/data transfer receiver (WPDT Rx) with inductive links requires high power conversion efficiency (PCE) for safe IMD operation and high data rate for continuous telemetry.
