- Highly-Integrated Light Sensing System with RF Harvesting and Transmission in Commercial N-Type IGZO Flexible Technology
A sticker-like light sensing system is demonstrated in flexible N type-only IGZO TFT. It reuses RF signals for harvested battery charging and backscattered communications, and repurposes resistors as light sensors. Low-power operation is enabled by techniques for state-of-the-art efficiency in voltage regulation, signal amplification, data conversion and pseudo-dynamic logic. Indoor light sensing and 0.9 GHz data transmission are demonstrated with 2.02mm2 area at 15.5μW (<1% duty cycle).
