Abstract: Although energy harvesting has been around for years, it still struggles to find widespread acceptance. One reason is the cost of harvesters and the associated electronics. In this work, we use LEDs as cost effective energy harvesters. Their production in very large quantities has made them price competitive. They can also be easily integrated in production flows. Despite their inefficiency when used as harvesters, they can be an alternative in applications where enough light is available. With 3 to 5 LEDs, we can accumulate enough energy to send messages with proprietary or Bluetooth Smart compatible frames.
