摘要： A device for continuously measuring the local skin sweating rate includes a sensor (1) used for applying to human skin at a measuring point and an air supply element (10) for supplying dehumidified air to the sensor (1). A first chamber (3) is formed between the sensor and the skin for mixing water vapor perspired from the skin and the dehumidified air supplied from the air supply element. A second chamber (6) is also formed within the sensor (1) and connected with the first chamber (3) through a communicating hole (31). The device further includes a humidity detector (4) in the second chamber. The humidity detector (4) varies its capacitance according to the relative humidity of the mixture. A temperature detecting element (5) is disposed in the second chamber for detecting the temperature in the second chamber and for outputing signals corresponding to the temperature. A humidity detector output element (7) is mounted on the sensor (1) and is electrically connected with the humidity detector (4) for outputing a humidity signal. A processor (18) calculates the sweating rate, which is independent of the temperature of the mixture, based on the humidity and temperature signals. An element is provided for continuously recording the data of the sweating rate obtained from the processor.

摘要： PURPOSE:To enable computation and display of an absolute quantity of sweat which is irrelevant to the temperature of air moisture by measuring simultaneously the relative humidity and temperature of the mixed air moisture of moisture (sweat) and air by providing a relative humidity detecting means and a temperature detecting means inside a capsule. CONSTITUTION:An opening of a front chamber 3 of a capsule is so formed as to come into close contact with the surface of a skin 2. A humidity sensor 4 in a rear chamber 6 is sensitive to the relative humidity in air moisture diffused and mixed in the front chamber 3 and a corresponding change in an electrostatic capacity appears as a change in a frequency of an oscillator 7 and is converted 12 and subjected to sensitivity adjustment by an amplifier 13. An oscillator 8 is formed on the same substrate as an oscillator 7 and its oscillation frequency changes in the same way as the oscillation frequency of the oscillator 7 which depends on a temperature. An output of the oscillator 8 is supplied, together with an output of the amplifier 13, to a differential amplifier 17 through a converter 15 and the amplifier 16 and computed therein. An output voltage of the amplifier 17 corresponding to the air moisture evaporated from the skin wherefrom a change in the temperature is removed is processed in a digital computation circuit 18 together with an output voltage of an amplifier 14 corresponding to the temperature of the air moisture measured by a sensor 5, and then the quantity of sweat and others are displayed and recorded by a pen recorder 19 and a printer 20.
