Abstract
Wireless in automation is seen in a growing number of monitoring applications. These can be primary sensors that monitor a process or secondary sensors which monitor an asset which is part of a process like a pump. This paper shows that energy harvesting is one enabler to leverage the full benefit from wireless installations and discusses the requirements for different applications. At least three power classes spanning the range from a few 100 μW to several 10 mW can be distinguished and various harvesting schemes exist to deliver that power. The cost figure of an energy harvester will be critical to reach mass applications serving the industrial internet of things.
