I-Chieh Chen Award Candidate Attention Evaluation in Different Lighting Environments by Using EEG and Empirical Mode Decomposition
I-Chieh Chen;Chin-Hsien Wu;Yi-Chun Chen

This study aims to evaluate users’ attention levels under different lighting environments by using brainwaves. The empirical mode decomposition followed by Fourier transforms is used to analyze the signals. After that, we utilize the improved power spectra and band-power histograms to compare the brainwaves by binary discrimination tasks.

Chien-Nan Chen Award Candidate Development of see-through binocular synchronous pupilometer
Chien-Nan Chen;Yi-Chun Tasi;Yung-Jhe Yan;Mei-Lan Ko;Ni-Chung Lee;Mang Ou-Yang

This research brings out a non-invasive, see-through binocular synchronous pupilometer to detect ANS. From the related research, the neurotransmission could be observed the response of the human’s pupils. We develop two pupilometers synchronously with a deviation less than 1/60 second to record the response of two pupils.

Bo-Shun Jaing Award Candidate Electrical Detection of Streptavidin-Biotin Complex Using IGZO Thin Film Transistors Integrated with Microfluidic Channels
Bo-Shun Jaing;Jian-Jang Huang;Nian-Ting Wu

We demonstrate an IGZO-TFT-based biosensor integrated with a Y-type external microfluidic channels for the detection of the mixing reaction situation of the Streptavidin and Biotin. By observing the real-time current change of the TFT biosensor, the biochemical reaction can be analyzed.

Chien-Chun Chen Award Candidate Photonic Crystal Biosensor for Glucose Detection
Chien-Chun Chen;Yu-Yang Liao;Yung-Tsan Chen;Jian-Jang Huang

Here we demonstrate a photonic crystal (PhC) sensor. The PhCs are able to diffract optical beams to various angles in the space. The critical wavelength that satisfies the phase matching or becomes evanescent is used to analyze the target. In the glucose detection, our sensor demonstrates high sensitivity.

Hsiung Chan-Te Award Candidate Real-time, Unprocessed, whole blood sensing using microfluidic chip incorporated with guided-mode resonance biosensor
Hsiung Chan-Te;Tsai Meng-Zhe;Chen Yang;Huang Cheng-Sheng;Hsu Hsin-Yun;Hsieh Pei-Ying

We demonstrate the detection of C-creative protein from whole blood by using a system consisting of a microfluidic chip and a guided-mode resonance biosensor. The chip includes an array of microposts for filtering blood cells and allows only plasma to flow through and reach the GMR biosensor for real-time monitoring.

Yu-Zi Lin Award Candidate Isotropic Quantitative Differential Phase Contrast Microscopy
Yu-Zi Lin;Hsi-Hsun Chen;Kuang-Yuh Huang;Yuan Luo

To improve the accuracy and stability of phase recovery in conventional DPC effectively, we propose a new illumination method to achieve isotropic differential phase contrast (iDPC) efficiently. Our iDPC is implemented with a partially coherent microscopy, and a TFT shield to modulate the illumination pattern.

Tzu Hsin Fan Detecting hard tissue in vivo by near-infrared
Tzu Hsin Fan

We use the new measurement of bone mineral density (BMD) to predict osteoporosis. Its performance is tested on 10 subjects by nears infrared (NIR) image system. Comparing with the dual energy x-ray absorptiometry (DXA) and get the excellent correlation coefficient.
