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.

The working electrode being a contact-detecting electrode can be replaced by another contact-detecting electrode with different sensing membrane. The reference electrode includes a polymeric membrane with ion material covering silver/silver chloride (Ag/AgCl) electrode to provide a fixed and stable electrical potential. The working electrode may be a contact-detecting electrode having a sensing membrane.

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.
