Self-power generation type transmitter
First Claim
1. A self-power generation type transmitter comprising:
- a power generating part for generating power by applying distortion to piezoelectric elements, a charging part for repeatedly charging generated power and a transmitting part for transmitting a signal by the charged power, wherein when an amount of charged power reaches a level at which the signal can be transmitted, the electric power is supplied to the transmitting part from the charging part.

Abstract
In a self-power generation type transmitter, piezoelectric elements are used as a power source for transmission and generated power is efficiently utilized so that the transmission of a signal requiring a relatively high electric power can be performed. The self-power generation type transmitter includes a power generating part 2 for generating electric power by applying distortion to piezoelectric elements 21, a charging part 3 for repeatedly charging generated power, and a transmitting part 4 for transmitting a signal by the charged power. When an amount of charged power reaches a level at which the signal can be transmitted, the electric power is supplied to the transmitting part from the charging part.
