The present paper introduces commercial components, circuit techniques and design considerations for energy harvesting power supplies in mobile communications. Transforming voltage levels is discussed as well as considerations to use energy storage elements. Furthermore a control method to decrease the power consumption of the communication module is presented. A hardware demonstrator with fully energy-autarkic thermo-electrical power supply is introduced. At last visions of the power supplies future for mobile devices are outlined.
