Circuit and method to startup from very low voltages and improve energy harvesting efficiency in thermoelectric harvesters

摘要: An energy harvesting system is provided that includes a startup module for starting the operation from completely OFF state, The uses mechanical vibrations due to motion trigger switch which permits charge one or more first capacitive elements so as reach defined voltage. A storage buffers obtained thermoelectric harvester be used by load device. commences storing when voltage has been reached allowing charging of second DC-DC converter provides regulated device after transferred harvester. determines whether and releases stored in
