"High-resolution proximity sensor using flexible semi-transparent organic photo detector";
Organic Electronics, 49 (2017), 305 - 312.

English abstract:
We propose a flexible proximity sensor to detect sub-centimeter distance with an ultra-high displacement
resolution. The proximity sensor is realized by integrating a semi-transparent organic photo detector
with a transparent top electrode and a finger-type bottom electrode. By placing the semitransparent
finger-type photodetector on a light source, such as a light-emitting diode (LED), the
photodetector can detect the light reflected from an object on top of the sensor. With the highly compact
structure, the detecting range is from 1 mm to 30 mm. From 1 mm to 10 mm, the sensor is particularly
sensitive and delivers a resolution of 1 mm. The air-stable photodetector can also be fabricated on a
flexible substrate without encapsulation, enabling the integration with arbitrary light sources. After 1000
times bending, the flexible photodetector shows no obvious degradation.
