摘要： An optical gas concentration sensor and method for measuring blood gas based on the light adsorption sensing technique are disclosed. The optical gas concentration sensor comprises a light source, a photo detector, and a gas filtering membrane for separating the indicator and a liquid. A gas in the liquid diffuses to the indicator through the gas filtering membrane so as to change the color of the indicator due to the chemical reaction occurred between the indicator and the gas. Then, the photo detector receives the light passing though the reacted indicator from the light source. The gas concentration is determined based on pH-sensitive absorbance spectrum of the indicator.

摘要： A data acquisition system for a solid-state urea biosensor uses an amplifier, a low-pass filter and a data acquisition card to acquire and relay data to a computer to be analyzed by a signal analysis program and displayed on a display panel. The biosensor includes a substrate, and three individual sensing areas separated by an insulating layer on the substrate. Each individual sensing area contains a conductive layer on the substrate, and a pH sensitive membrane is deposited thereon. An enzyme layer is deposited on one of the pH sensitive membranes to form a working electrode. The other two sensing areas are a quasi-reference electrode and a contrast electrode, respectively. The signals are transferred to an instrumentation amplifier. The amplified signals are then transferred to a low-pass filter. The filtered signals are analyzed by the program and then displayed on the display panel.
