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 …
