Energy self-sufficient radiofrequency transmitter

摘要

The energy self-sufficient radiofrequency transmitter has at least one electromechanical transducer with a rectifier circuit connected downstream and with a voltage converter circuit. A logic circuit configuration is connected to the voltage converter circuit. The logic circuit configuration has a sequence controller a memory in which an identification code is stored. The energy self-sufficient radiofrequency transmitter also has a radiofrequency transmission stage that is connected to the logic circuit configuration and a transmission antenna.
