Capturing light: New ergonomic photodetector for the trillion-sensor era

Light-to-frequency conversion circuits (LFCs) are often used to overcome setbacks faced by conventional ultra-low power light sensors. However, use of LFCs can lead to chip area wastage and poor performance of photosensors. Researchers have now developed a highly photosensitive LFC with improved chip area economy, high tuneability, and superior compatibility with flexible electronics. This novel photodetector system can be used in the newly envisioned Internet-of-things (IOT) sensor systems.
