Abstract

An embodiment of the invention discloses a pulse detection device and a manufacturing method thereof. The pulse detection device comprises: a piezoelectric sensing layer including a flexible piezoelectric electret film and two metal electrodes arranged on the upper and lower surfaces of the flexible piezoelectric electret film respectively, wherein the two metal electrodes are used for outputtingcharge quantity changes when the flexible piezoelectric electret film deforms; a data processing mechanism used for connecting the two metal electrodes to receive charge quantity changes output by thetwo metal electrodes, for determining a potential change according to the charge quantity changes, and for transmitting the potential change to a data receiving terminal. The technical problem that apulse detection device of the prior art has complex structure is solved; structural complexity of the pulse detection device is decreased.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical devices, in particular to a pulse detection device and a manufacturing method thereof. Background technique [0002] When a large amount of blood enters the artery, the pressure of the artery will increase and the diameter of the artery will expand. The expansion of the artery can be felt at a shallower part of the body surface, which is the so-called pulse. As an information carrier closely related to cardiovascular activity, pulse wave contains extremely rich pathological and physiological information of the cardiovascular system, which is helpful for the diagnosis and analysis of the health status of the body. [0003] The pulse wave signal detection technology has been greatly developed in recent decades. In the existing pulse wave detection technology, the method of "pulse finger pressure" has no scientific data, and the pressure change of the fingertip has a great influence on th...
