Popis:	This article describes the design principles of a quartz pulse wave sensor with capacitive control for healthcare solutions. A constructive model of a quartz crystal sensor (QCS) with a frequency output is considered and an algorithm for linearizing the QCS calibration characteristics is presented. An electrical QCS model is constructed and a numerical analysis of control characteristics in the presence of parasitic electrical connections arising from the practical implementation of the principle of capacitive control is carried out. A simulation model of a pulse oscillation sensor based on a QCS with capacitive control is presented and a numerical simulation of the stress-strain state of a corrugated membrane in COMSOL/Multiphysics is carried out. Examples of practical application of pulse wave QCS in systems of sphygmography for determining the parameters of the human cardiovascular system are given.
