Abstract

A portable sensor assembly, comprising a metal casing (1) provided with a pulse sensing mechanism therein; the pulse sensing mechanism consists of a PCB (2), a piezoelectric thin film (3) disposed on the PCB (2), and a pulse contact (4) securely disposed on the outer side of the piezoelectric thin film (3); the PCB (2) is provided with a piezoelectric thin film vibration stroke working cavity (2a) corresponding to the piezoelectric thin film (3); the anode and cathode of the PCB (2) are mutually connected to the anode and cathode of the piezoelectric thin film (3); the PCB (2) is connected to an external data collecting instrument circuit; the casing (1) is provided with a hole (1a) accommodating the pulse contact (4), and the contact extends out of the hole; and the pulse contact (4) contacts a human body.

Description

technical field [0001] The present invention relates to a pulse sensor and, more particularly, to a portable sensor assembly. Background technique [0002] Pulse wave is one of the important parameters of human cardiovascular system. When the heart contracts and relaxes periodically, the blood flow from the ventricle into the aorta will start from the active root in the form of a wave and propagate along the arterial system. This wave is the pulse wave. The pulse wave is transmitted in the arterial system, and is continuously reflected in the branches at different positions downstream, so that the pulse wave is not only affected by the heart itself, but also by various physiological and pathological factors flowing through the arteries and branches at all levels. Such as vascular resistance, blood vessel wall elasticity and blood viscosity, etc., so the intensity and waveform of the reflected wave reflected from the downstream peripheral arteries will vary greatly with diff...
