摘要
In a power feeding apparatus A1, a drive circuit 11 receives electrical power supplied from a power supply 10 and generates a driving signal V. In response to this, an actuator 12 vibrates, and this vibration is transmitted through vibration transmission members 14 and 20 to a converter 21 of a power receiving apparatus B1. The converter 21 includes a piezoelectric device. Accordingly, vibration is converted into voltage, thus generating an electromotive voltage Vg. The electromotive voltage Vg is rectified by a rectification circuit 23, and a large-capacitance capacitor 24 is charged with rectified voltage. A clock circuit 25 receives power from the large-capacitance capacitor 24 and measures time. IMAGE
