摘要： In this present invention it was fabricated to be relates to manufacturing a ceramic interface electrochemical reference electrode for use together with biomedical sensors. Most potentiometric biomedical sensors must have the need to be connected to a reference electrode to offer the readout circuit a stable voltage in the different solutions when measuring for providing that can provide a standard comparing voltage to avoid measuring errors caused by an unstable environment. Usually, However, the presently available commercial reference electrode we used is too big in size and inconvenient to store. For this reason we develop the ceramic interface electrochemical reference electrode which can minimize volume and need not to be preserved in the saturated solution for biosensor. Therefore, the ceramic interface electrochemical reference electrode of the present invention does not need to be stored in solution and can be minimized for use in future sensors. In addition, the present invention also relates to a ceramic interface electrochemical reference electrode.

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.
