Description

1 f Изобретение относитс  к области медицинской техники и может быть использовано во влагометрии материалов и веществ, например, кожи человека. Известен датчик в устройстве дл  изме рени  потоотделени , содержащий параллель но установленные на изол ционной пластине электроды. Целью изобретени   вл етс  повышение чувствительности датчика. Это достигаетс  тем, что в основании изол ционной пластины установлены герметична  камера на}сош1ени  вла1: овыделени  а электроды расположены вдоль продольных стенок камеры по всей их высоте и с выступом из нее. На чертеже изображен предлагаемый датчик в разрезе. Он содержит изол ционную пластину 1, в основании которой установлена герметична  камера 2 накоплени  влаговыделени , электроды 3 расположены вдоль продольныз стенок камеры 2 по всей их высоте и с выступом из нее.. Датчик накладывают на исследуемый участок кожи, при этом увеличиваетс  его электрическа  емкость, а при включении электродов 3 в цепь измер етс  изменение электрических параметров цепи, соответст вующее измененигр влажности исследуемого объекта. Пред м е т изобретени  Датчик влажности, содержащий изол ционную пластину и параллельно установленные на ней электроды, от.личающийс / тем, что, с целью повыщени  чувствительно сти, в основании изол ционной пластины | установлена герметична  камера накоплени  влаговыделенн , а электроды расположены вдоль продольных стенок камеры по всей их высоте и с выступом .из нее.1 f The invention relates to the field of medical technology and can be used in moisture measurement of materials and substances, for example, human skin. A known sensor in a device for measuring perspiration, containing electrodes mounted in parallel on an insulating plate. The aim of the invention is to increase the sensitivity of the sensor. This is achieved by the fact that a sealed chamber is mounted on the base of the insulating plate at the base of the insulating plate: optics and electrodes are located along the longitudinal walls of the chamber along their entire height and with a protrusion from it. The drawing shows the proposed sensor in section. It contains an insulating plate 1, at the base of which an airtight accumulation chamber 2 is installed, the electrodes 3 are located along the longitudinal walls of the chamber 2 along their entire height and with a protrusion from it. The sensor is applied to the skin area under investigation, and when electrodes 3 are switched on in the circuit, a change in the electrical parameters of the circuit is measured, corresponding to a change in the humidity of the object under study. BACKGROUND OF THE INVENTION A moisture sensor comprising an insulating plate and electrodes installed in parallel with it, which is distinguished by the fact that, in order to increase the sensitivity, at the base of the insulating plate | a sealed accumulation chamber is installed, moisture separated, and the electrodes are located along the longitudinal walls of the chamber along their entire height and with a protrusion from it.
