Abstract (en)
[origin: WO2018167082A1] The invention relates to the time-resolved measurement of the blood pressure, the arterial elasticity, the pulse wave, the pulse wave transit time and the pulse wave velocity and/or changes of the cardiac output and/or of the cardiac output of an object, namely a human or animal body, using pressure sensors for time-resolved measurement of the energy pulse wave. According to the invention, a pressure sensor unit is provided for the time-resolved pressure measurement of the pressure exerted onto the skin by a pulse wave, wherein the pressure sensor unit is an air and/or gas pressure sensor and/or is designed to change at least one electrical conductance and/or resistance when subjected to pressure. In particular, the pressure sensor unit has at least two conductor path assemblies, in particular networks of conductor paths, and a functional polymer which is designed to be compressed when subjected to pressure and to produce and/or change the contact between the conductor path assemblies. Alternatively, the pressure sensor unit has at least two conductive layers with an intermediate space arranged between them, and the pressure sensor unit may be configured in such a manner that, by being subjected to pressure, the intermediate space is compressed and/or in particular the capacitance of the arrangement consisting of the two conductive layers changes.
