An energy harvesting circuit includes one or more broadband or narrow band antennas to detect WIFI (wireless fidelity) or other RF (radio frequency) signals. The signals are rectified and voltage multiplied, and the resultant DC voltage is provided to a power management circuit. The output of the power management circuit charges a lithium battery or other storage device within the energy harvesting circuit. The energy stored in the battery or storage device is provided through a DC/DC converter circuit to a USB output connector to power or recharge the b...
1. An energy harvesting device, which comprises: at least one antenna for receiving a transmitted radio frequency (RF) signal, the at least one antenna converting the received RF signal to an RF electrical signal;at least one RF-to-DC rectifier circuit, the at least one RF-to-DC rectifier circuit being operatively connected to the at least one antenna and converting the RF electrical signal to a direct current (DC) voltage;a first storage device, the first storage device being operatively connected to the at least one RF-to-DC rectifier circuit and being...
