summary

A self-contained system combines a flexible imaging surface, photodetectors, a control circuit for power management and wireless comms, and a 3D-printed optical mask to tune field of view. It runs on self-powered by indoor ambient light and supports 0D/1D/2D sensing. Results: door and pill bottle open/close at 100% accuracy, liquid type classification 90% and level error 5.6 mm, step counting 99%, multitouch error drops from 8 mm to 4 mm and hover accuracy rises 82%→95%, presence detection to 1.4 m. Prototype work with organic semiconductor-based surfaces shows thin, flexible feasibility.
