A simultaneous imaging and energy harvesting sensor is in the news. Samuel Moore at IEEE Spectrum informed readers that a team of four from University of Michigan published their paper describing what they achieved. They built a prototype sensor, and what it does—-think of a future camera that just about watches you non-stop—is described in the journal, IEEE Electron Device Letters.

The article is titled “Simultaneous Imaging and Energy Harvesting in CMOS Image Sensor Pixels.” The four authors are from University of Michigan: Sung-Yun Park, Kyuseok Lee, Hyunsoo Song and Euisik Yoon.

Their technology “puts the equivalent of a solar cell under each pixel,” said IEEE Spectrum.
