“…The power factor is an order smaller than this work, and the additional etching process requires a modified CMOS process and thus may jeopardize the process stability. A CMOS TEG based on co-planar thermocouple design has improved the power factor to 0.0417 W/cm 2 K 2 [2] and the most recent CMOS TEG design based on stacked poly-silicon thermocouples can deliver 0.0427 W/cm 2 K 2 [3]. This work based on quantum well-like thermocouples achieves the best performance and it is also CMOS compatible.…”

“…Micro-thermoelectric generators (TEG) have been successfully developed by CMOS process [1][2][3], where silicon-based design has the advantage of using thin-film process in semiconductor infrastructure for batch production. This development is a major improvement over the previous works by electrochemical thickfilm deposition of V-VI thermoelectric compounds [4] and by thin-film deposition of polycrystalline silicon/germanium [5,6].…”

Wireless sensor networks (WSNs) design requires multidisciplinary approach in the field of wireless communication, embedded systems, networking, digital signal processing, hardware and software engineering. Major factors to influence the WSNs design are hardware and software constraints, scalability, cost, transmission media, network topology and power consumption etc. Most of WSN nodes are battery powered. With the limited capacity of batteries to power WSN nodes, need of energy harvester or scavenger is required to harvest or scavenge energy from the environment to improve the life-time of the sensor node. The harvested or scavenged energy is converted by power converters to recharge the sensor nodes or for the storage devices. This paper gives current developments of energy harvesting technologies, power converters and storage devices proposed by various researchers in WSNs along with some open research problems.

Thermoelectric generators (TEG) are capable of transforming waste heat directly into electric power. They are very reliable and do not need any kind of maintenance at all, which makes them interesting for a wide range of applications. To design specific TEG for different purposes a fast and cheap tool is needed to optimize the geometric structure based on the used materials and boundary conditions. Therefore, we tested a commercial finite element method simulation versus a self-implemented analytic calculation and compared them with real measurements. The results of the two simulations types were in good agreement to each other and near by the measured value. Beside the length of the thermocouple as a well-known design parameter, two more relevant parameters have been proposed. The thermal conduction of the hot/cold side and the geometrical matching of the n/p-doped thermoelectric material have a great influence on the device performance
