Radio Sensors Powered by Ambient Energy: From Strange Ideas to Mass Market Products

Keywords: energy harvesting, energy scavenging, wireless sensors, energy autonomous sensors, ambient energy

Only 10 years ago the idea of reliably operating a multitude of different radio sensors solely with ambient energy seemed unreal. The right kind of topic for inventors dreaming of the perpetuum mobile…

These days, however, if one enters the term “energy harvesting” into an internet search engine, one is returned about half a million hits. No doubt, the subject has become more than simply another topic of conversation.
Surprisingly, however, only very few products exist on the market that hold the potential for high unit numbers in mass applications. The article outlines significant technical challenges and their solutions on the way to producing energy autarkic radio sensors in large scale, using selected products as examples.
