Energy Harvesting in Automotive Key fob Application
This paper proposes to replace the 3V lithium coin cell automotive keyfob battery having 200 mAh capacity and which can last up to 75,000 key press events or two to three years with a RF energy harvesting circuit involving voltage multiplier circuit consisting of zero bias schottky detector diodes and a hybrid energy storage capacitor.
Energy Harvesting Techniques for Low Power RF Sensors
This paper presents the research conducted and the progress achieved in the design and implementation of the low cost Energy Harvesting System for low power remote RF Sensor applications. In this implementation, conventional battery is replaced with a super-capacitor which is charged by DC voltage harvested out of RF EM waves.
