Seven years ago, I wrote an 11 Myths article on energy harvesting for Electronic Design. The article was written to dispel some of the more egregious misconceptions we were seeing at the time.

Back in 2019, energy harvesting could hardly be said to be in its infancy. Jimmy Carter had solar panels installed on the White House back in 1979, and huge advances had been happening in PV, piezo, RF, and thermal generation in terms of extraction efficiency. While it was clear that energy harvesting was a no-brainer for powering the IoT revolution, I must admit it wasn’t so clear which applications would be first adopted, nor was the pace of improvement that now makes the technology pervasive.
