Abstract
A wearable power harvesting system includes a knitted fabric rectenna including an antenna adapted to receive radio-frequency energy within a desired frequency band and a rectifier circuit that converts received radio-frequency energy into a DC current and voltage. A knitted fabric load/storage unit stores DC power from the rectifier circuit. The power harvesting system is adapted to harvest the radio-frequency energy within the desired frequency band, which may include WLAN frequencies such as the standard 2.4 GHz and 5 GHz WLAN standard frequencies.
