What at first was intended as a novel and hard to copy system for authenticity and verification of security documents has lately gained interest as an enabler for the hype “internet of things”. One of the major obstacles for getting small things connected to each other and communicating over the internet is how to solve the power supply issue. With this low cost and all-printed energy harvesting system it will be possible to power up communication systems without onboard power sources and without wired connections.
