摘要：
[0039] A sensor unit intended for use in devices for simultaneous measurement of human tissue impedance and pressure, which identifies human hemodynamic parameters. The sensor unit of the device attached to skin surface segment includes a base with a recess, in which a piezoelectric element of pressure sensor is installed. The unit also includes a flexible membrane mounted on the base and overlapping said recess. First and second electrodes are attached to the outer surface of the membrane. The first electrode is mounted opposite the recess and is capable of moving together with the membrane. The second static electrode surrounds the first electrode. A central support is mounted between the first electrode and the piezoelectric element. Being connected to the electrical outputs of said impedance measurement sensor, the first and second electrodes are aligned so as to permit contact with skin surface. Such an embodiment makes the sensor unit smaller in dimensions. At the same time, the operational stability and sensitivity of sensors are increased.
