    摘要: The invention provides a method of fabrication of a solid-state urea biosensor and its data acquisition system. 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 sensing signals are transferred to an instrumentation amplifier by conductive wires. The sensing signals are then transferred to a low-pass filter to reduce the high frequency noise. A data acquisition card is employed to transfer the sensing signals to a computer. The sensing signals are analyzed by the program of the data acquisition system. The data are then displayed on the display panel.

    摘要: A process for fabricating a whole solid-state pH sensing device by using the polypyrrole as the contrast pH detector and a whole solid-state pH sensing device fabricated by the process are disclosed, wherein said device is a differential pair framework potential electrochemical sensing device fabricated by using a non-insulating solid-state inorganic ion-sensing membrane and a polypyrrole sensing membrane. The largest difference between the device of the present invention and the conventional potentiometric type pH sensor is that the sensor of the invention is a solid-state planar sensor. The differential pair framework uses tin dioxide as the ion-sensing membrane and the reference electrode, and uses a polypyrrole sensor as the differential sensor, wherein the sensitivity of tin dioxide is good and has a value up to 57 mV/pH, and the sensitivity of polypyrrole is about 27 mV/pH. These lead the sensitivity of the whole solid-state pH Sensing device to a value of 30 mV/pH and exhibits good linearity, so that the sensing device framework has practicability. Since the sensitivity of the polypyrrole can be controlled by means of its polymerization, a sensing device with controllable sensitivity can be fabricated for applying to the fabrication of a pH sensor or a biosensor.

    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.
