Rapid-charging wearable wireless device

Abstract

A wearable wireless device includes a wireless transceiver coupled to a first antenna, an energy harvester coupled to a second antenna, and a supercapacitor coupled to the energy harvester. The wireless transceiver may be configured to receive a first wireless signal from a paired wireless communication device via the first antenna. The energy harvester may be configured to convert radio-frequency (RF) energy received by the second antenna into a charge. In some instances, the energy harvester may be further configured to charge the supercapacitor in response to a presence of the RF energy. The supercapacitor may be configured to store the charge converted by the energy harvester and provide power to the wireless transceiver. In some instances, the supercapacitor may be further configured to power one or more electronic components of the wearable wireless device with the stored charge.
