研制了一种用于生理液体的新型电化学-热流传感器。该传感器由铂电阻加热器和对二甲苯C衬底上的铂传感电极组成，使其具有灵活性和完全的生物兼容性。在加热过程中，利用传感电极上电化学阻抗的变化来检测温度的变化，并在过热温度仅为1摄氏度的情况下实现了高灵敏度的流动测量。该传感器的生物兼容性和低过热温度使其成为体内慢性应用的理想候选者。[2016-0170]
A novel electrochemical-thermal flow sensor was developed for use in physiological liquids. The sensor was constructed out of a platinum resistive heater and platinum sensing electrodes on a Parylene C substrate, rendering it flexible and fully biocompatible. During heating, changes in electrochemical impedance across the sensing electrodes were used to detect changes in temperature, and highly sensitive flow measurements were achieved with overheat temperatures of only 1 degrees C. The sensor's biocompatibility and low overheat temperature make it an ideal candidate for chronic in vivo applications. [2016-0170]
