Self-Powered Gesture Recognition with Ambient Light
summary
A self-powered gesture module uses small photodiodes operated in photovoltaic mode as both energy harvesters and sensors, with a prototype glass array of 48 solar cells and a watch version; it reads cell voltages at 35 Hz, runs recognition on an MCU, and harvests enough indoor light to exceed the device draw (glass ~34.6 µW), achieves up to 99.7% precision, and limits sensing to about 3 cm range.
