Problems solved by technology

The defect of this method is that the noise caused by mechanical impact is very large. For example, the noise of an electronic lighter is produced by a spring hitting the piezoelectric ceramic 10P
In addition, hitting the surface of the piezoelectric ceramic 10P will significantly shorten the service life of the piezoelectric ceramic 10P, and the piezoelectric ceramic 10P is easily damaged, and the device cannot be used for a long time, and the practicability is poor.
In addition, the energy generated by one blow to the piezoceramic 10P is so small that it is only enough to send a few bits of simple control information
In the field of remote control, because there are many wireless devices in the environment, in order to enhance the reliability and stability of wireless signals, usually wireless signals need to contain a long series of message data such as boot codes, address codes, data, and check codes. However, the energy generated by the existing percussive piezoelectric generator cannot support the communication circuit to send such a long message data
