Abstract
A Radio Frequency (RF) power harvesting system is proposed to wirelessly power medical devices (e.g., wearable or implantable sensors, etc). The proposed system allows medical devices to operate even when there is little RF energy available. The power receiver consists of a printed antenna, well-tuned rectifier, power management chip, and a charge storage device. For a 100mW transmitter operating at 2.4GHz, a 4F super-capacitor can be wirelessly recharged to 3V. Future design considerations are discussed, viz. flexibility of the harvester circuit and wide band harvesting.
