By integrating ultra-flexible green and red PLEDs with an OPD, a flexible and conformable reflective pulse oximetry has been demonstrated. In order to detect pulse waves and blood oxygen levels, the device was turned over and wrapped around a finger. While the driving voltage of the PLEDs was set at 5 V, the open-circuit voltage (Voc) of the OPD was monitored for measuring the absorption of green and red light in the blood to the pulse.

The spectrum analysis for the noninvasive examination of orchid virus is a challenge due to time-varied biological conditions of live individuals. In this work, two algorithm analysis were proposed to discriminate orchid diseases. The sensitivities are 77.5 % and 88 % for the calibration analysis and Gaussian decomposition analysis, separately.

Yi-Lun Chiang Protein quantitation based on optical absorption of dye-doped liquid crystal
Yi-Lun Chiang;Mon-Juan Lee;Wei Lee

We developed a biosensing method using a dye-doped liquid crystal. The working system was demonstrated with a black dichroic dye possessing high dichroic ratio for promoting the sensitivity in detecting biomolecules. A polarizer used to make incident light linearly polarized enhanced the resolving power of the detection system.
