    摘要： Microsensors that include an integrated thermal energy source and an integrated temperature sensor are capable of providing localized heating and temperature control of individual sensing regions within the microsensor. Localized temperature control allows analyte detection to be carried out at the same temperatures or substantially the same temperatures at which the sensor is calibrated. By carrying out the sensing near the calibration temperature, more accurate results can be obtained. In addition, the temperature of the sensing region can be controlled so that chemical reactions involving the analyte in the sensing region occur near their peak reaction rate. Carrying out the sensing near the peak reaction rate improves the sensitivity of the sensor which is important as sensor dimensions decrease and the magnitude of the generated signals decreases.

    摘要翻译： 包括集成热能源和集成温度传感器的微型传感器能够提供微传感器内各个感测区域的局部加热和温度控制。 局部温度控制允许分析物检测在相同的温度或基本相同的温度下进行，在此温度下传感器被校准。 通过在校准温度附近进行感测，可以获得更准确的结果。 此外，可以控制感测区域的温度，使得涉及感测区域中的分析物的化学反应在峰值反应速率附近发生。 在峰值反应速率附近进行感测提高了传感器的灵敏度，这在传感器尺寸减小并且产生的信号的幅度减小时是重要的。

    摘要： A razor has an electrochemical sensor for sensing various characteristics, such as biological, chemical, temperature, humidity, and pressure. The electrochemical sensor is positioned within a razor head of the razor, but may be attached to and enclosed in the razor head housing or attached to a razor blade of the razor. The electrochemical sensor may be positioned at different locations within the housing and on the razor blades. The electrochemical sensor may be positioned such that a sensing surface is exposed to a shaving surface of a patient. The razor may also have various electrical components for processing signals generated by the electrochemical sensor and determining the presence or concentration of a chemical or biological marker. The data associated with the signals may be displayed, transmitted to a separate computing device, or stored in a memory.
