Abstract

An apparatus for transmission of wireless energy and an apparatus for reception of wireless energy are provided. The apparatus for transmission of wireless energy includes a natural energy conversion module, an energy converter, and an energy transmitter. The natural energy conversion module receives the natural energy and converts the natural energy into a first electric energy. The energy converter is electrically connected to the natural energy conversion module and converts the first electric energy into the wireless energy. The energy transmitter is electrically connected to the energy converter and transmits the wireless energy to an energy receiver. The energy transmitter is configured to monitor a relative position between the transmitter and an energy receiver and a charge status of the energy receiver so as to activate the energy transmitter to transmit the wireless energy in response to the relative position being less than predetermined threshold and to adjust the wireless energy according to the relative position and the charge status. The apparatus for reception of wireless energy includes an energy receiver to receive a wireless energy and convert the wireless energy into a second electric energy. The apparatus for reception of wireless energy is configured to monitor a charge status and a relative position between the energy receiver and the energy transmitter.
