New ultra-low-power shape recognition

A new shape-recognition sensor developed by CEA-Leti and STMicroelectronics is making headlines for its extremely-low power consumption, which, at 10 microwatts, is 1,000 times lower than commercially-available solutions. Five years in the making, the innovation is protected by a handful of patents on its pixel reading mode, data formatting, machine learning algorithms, optimized architecture, and other distinguishing features.

The active standby system allows the sensor to wake up when it detects movement and recognize a class of previously-learned shapes, such as faces, without the need for an external controller. These capabilities are a perfect match for smartphone integration. The device could also be of use in home automation, building surveillance, and automotive applications.
