We report a device combining a thermoelectric device and a mixture of 5 types of phase transition materials those have phase transition temperature near the room temperature. The device act as an energy harvester that generates electric power using ambient temperature cycles. The operating temperature range of the energy harvester was −0.2 °C – 37.2 °C. The energy harvester generated maximum electric power of 300 micro-W when it was placed in an Stevenson screen.
