Energy harvesting is an increasingly important capability for a lot of applications. It can be used in biomedical implants but also in other embedded systems. An energy harvesting device needs a functional and efficient power management. Because of the low energy yield it is important to store the harvested energy until enough power is available to accomplish a task like sending data outside the human body. Therefore Li-ion batteries and capacitors are used in this work. Furthermore a typical arrangement of an efficient energy harvesting circuit is discussed and tested.
