The energy grid is getting decentralized by utilization of renewable energy sources and local storage capabilities. This will contribute to increase the availability of electrical energy globally. Regardless, we will always have a demand for portable energy that is used by low-power wearables. Energy harvesters are a promising alternative to batteries to supplement a future […]

Energy harvesting is a process by which wireless and autonomous devices are able to capture, convert and store energy from external environmental sources like light, heat or motion. Ideally, these devices can be powered partially or completely by harvested energy, so that batteries and the power grid become redundant. The idea of energy harvesting is […]

The thermoelectric effect describes the direct conversion from thermal to electric energy and vise versa. This article provides a short history of thermoelectrics, from the discovery in the early 19th century, to the state of the art today and possible developments in the near future.   The discovery of thermoelectrics Already in 1794, Italien physicist […]
