Abstract
A hybrid electromagnetic (EM) and light energy harvester is proposed for autonomous IoT sensor. The hybrid energy harvester is comprised of dipole rectenna in 915MHz ISM band and flexible photovoltaic film. The photovoltaic film is integrated on metal surface at a certain distance from dipole antenna, which plays a role as a reflector. This integration has little effect on antenna performance and increase of antenna gain. A prototype of IoT sensor with proposed harvester is fabricated. The proposed hybrid energy harvester obtains DC power from both of energy sources which and can be used with IoT sensor.
