22.3 A 141µW sensor SoC on OLED/OPD substrate for SpO2/ExG monitoring sticker

Recently, OLED is replacing semiconductor LEDs in many applications for broader light emission and low fabrication cost. In addition, Organic Photo Detector (OPD) and OLED can be fabricated on the same substrate with the same process and the OLED film itself can be used for the integration substrate of the other functional ICs. In this paper, we present a new SpO2/ExG monitoring sticker integrating OLED/OPD with CMOS SoC. It combines the superior optical properties of organic material with the advanced functional performance of CMOS SoC.
