Wireless power supply method

摘要

There is provided a wireless-type power supply method that is applied to the case where an object to which energy is to be transmitted is relatively small, such as a micromachine, and that allows high-voltage electrical energy to be transmitted without using a wire. In this method, the optical energy from an light source is converted into high-voltage electrical energy by means of an energy transducer formed of either a piezoelectric element or a photovoltaic element on the above-described object, and the high-voltage electrical energy is supplied to an actuator, whereby the construction of the receiving side of the energy transmission is simplified.
