Abstract
A charging apparatus includes an antenna, a receiver, and a battery. The battery is charged by a harvester, which converts wireless energy sent by antenna to direct current and charges the battery. The harvester includes a sensor coil, a rectifier and voltage regulating filter. The wireless energy is converted by the sensor coil to alternating current (AC). The rectifier is electrically connected to the sensor coil for converting AC to direct current (DC). The voltage regulating filter is electrically connected to the rectifier to regulate DC. The battery can be charged by the wireless charge apparatus.
