Abstract
A wireless power transmission system includes a wireless power transmitting apparatus and a wireless power receiving apparatus. The wireless power transmitting apparatus includes a signal generator and an ultrasonic transmitting unit. The ultrasonic transmitting unit generates and outputs a focused ultrasonic wave according to a signal outputted from the signal generator. The wireless power receiving apparatus includes an ultrasonic receiving unit and a power conversion unit. The ultrasonic receiving unit receives the focused ultrasonic wave outputted from the wireless power transmitting apparatus and converts the focused ultrasonic wave into electrical power energy. The power conversion unit performs a power conversion on the electrical power energy and thereby provides the converted electrical power energy to a back-end circuit. The ultrasonic signal can also be encoded in the transmitting unit and subsequently decoded in the receiving unit as a means to remotely control the back-end circuit in the receiving unit.
