Abstract

A microfluid sensing device used to measure photo-electronic properties of a liquid includes a substrate, a patterned conductive layer, a hydrophobic layer, a photodiode layer, a transparent electrodelayer and a control circuit. The patterned conductive layer is disposed on the substrate and has a first electrode, a second electrode and a third electrode adjacent to but separated with each otherand arranged in sequence. The hydrophobic layer overlapped with the first and the second electrodes is used for carry the liquid. The photodiode layer is disposed on and directly in contact with the third electrode. The control circuit is connected to the first, the second and the third electrodes, by which the liquid can be drove to move over the hydrophobic layer and the photodiode layer.

Description

technical field [0001] The present invention relates to a biological micro-electromechanical system and its manufacturing method, in particular to a microfluidic sensing element. Background technique [0002] Bioinformatics uses methods such as applied mathematics, informatics, statistics and computer science to collect, screen, process and utilize various biological data. In the process of collecting, screening, processing and utilizing biological information, the preparation and analysis of biological samples require considerable manpower and time. How to achieve high selectivity, high sensitivity and rapid detection in complex samples with minimal preparation steps (simple) has become a major challenge in the industry. [0003] Biomedical microelectromechanical systems (Bio-MEMS) is the application of MEMS technology in the field of life sciences, which has the advantages of short analysis time, low sample consumption, automation, rapid parallel analysis and disposable. ...
