Ching-Fu Lin Organic-Semiconductor Sub-Centimeter Proximity Sensor with a Self-Calibration Function
Ching-Fu Lin;Chao-Hsuan Chen;Hsiao-Wen Zan;Chuang-Chuang Tsai

We fabricated an air-stable finger-type organic photodetector to serve as a proximity sensor to detect sub-centimeter distance (1 mm to 10 mm). By analyzing the sensing response from various reflecting objects with different irradiating light, we propose a self-calibration method with time-sequenced irradiation.

Chun-Po Yang An Amorphous Indium-Gallium-Oxide Bilayer Solar-Blind Photodetectors
Chun-Po Yang

We fabricated bi-layer a-IGO MSM UV PDs by in-situ co-sputtering method using Ga2O3 and In2O3 targets at room temperature on glass substrate. Under UV irradiations of cutoff wavelengths, the devices we reported could represent 4 orders magnitude of IPho/IDark ratio and 5 orders magnitude of UV-to-visible rejection ratio.

Bo-Han Qiu Fabrication of a High-Sensitive Humidity Sensor Using D-shaped fiber and Indium Tin Oxide Coatings
Bo-Han Qiu;Chuen-Lin Tien;Hao-Sheng Mao;Hong-Yi Lin

This paper presents a high-sensitivity relative humidity sensor based on ITO coatings and lossy mode resonance. A new humidity sensor has a highest sensitivity with D-shaped fiber residual thickness of 73 μm and ITO thin-film thickness of 23 nm. The sensitivity of the proposed humidity sensor is 8.609 nm/%RH.

Sin-Yi Jiang Effects of Metal Electrodes on High-mobility InWO Thin Film Transistor for High-resolution Display Applications
Sin-Yi Jiang

The high performance amorphous indium tungsten oxide (a-IWO) thin film transistor with different electrode was investigated for high-resolution display Applications. Aluminum is more suitable as source and drain because of its lower contact resistance. It leads to the a-IWO TFTs with Al electrode demonstrated high mobility to 28.34 cm2/V s.

Yi-Jun Jen Obliquely deposited Ag-SiO2 nanoheliex array
Yi-Jun Jen;Wei-Chih Liu;Chia-Liang Yu

In this work, two-turn SiO2 nanohelices are obliquely deposited upon one-turn Ag nanohelices to form an Ag-SiO2 nanoheliex array. Since the SiO2 nanohelices function as a grade index layer on the top of Ag nanohelix array, the wide angle light extinction Is is enhanced by reducing the reflection

Cheng-Chung Jaing Design and Implementation of Broadband Antireflection Coating for Luminescent Solar Concentrators
Shu-Chin Lin;Kai-Pin Yang;Wei-Han Chen;Yu-Chun Peng;Po-Chun Lu;Wei-Gwo Yu;Cheng-Chung Jaing;Yeuh-Yeong Liou;Bing-Mau Chen

Luminescent solar concentrators comprise thick glass with broadband antireflection coating deposited on the top surfaces and inorganic phosphor layers contacted on the bottom surfaces. Solar cells are contacted to the lateral surfaces of the glass. Experimental results show the broadband antireflection coating increased the short-circuit current of the solar cell.

Chih-Hsien Tsai Non-invasive measurement of heart rate and related applications using proximity sensor of cell phone
Chih-Hsien Tsai

We use non-invasive characteristics of the commercial proximity sensor to measure the heart rate. Under test people only need to put a finger on the sensor, so that can the heart rate of under test people can be measured. And even can be found there is no arrhythmia situation occurred.
