Pulse monitoring sensor, preparation method and pulse monitoring device and system

Abstract

The invention discloses a pulse monitoring sensor, a preparation method and a pulse monitoring device and system. The pulse monitoring sensor comprises a friction electricity generation part, a firstencapsulation layer and a second encapsulation layer, wherein the first and second encapsulation layers are used for encapsulating the friction electricity generation part. The friction electricity generation part comprises a first friction assembly and a second friction assembly which are stacked in sequence, the first friction assembly comprises a first electrode layer and a first high-molecularpolymer insulating layer which are stacked, and the second friction assembly comprises a second electrode layer. The first encapsulation layer is arranged on the surface of the portion, away from thefirst high-molecular polymer insulating layer, of the first electrode layer; the second encapsulation layer is arranged on the portion, away from the first friction assembly, of the second electrodelayer and the lateral surface of the friction electricity generation part; a concave-convex array structure is arranged on the surface, making contact with the skin of a user, of the second encapsulation layer. By means of the technical scheme, the sensitivity of the pulse monitoring sensor is improved, the pulse beat of the user can be accurately monitored, the structure and the manufacturing technology are simple, and the cost is low.

Description

technical field [0001] The invention relates to the field of human health monitoring, in particular to a pulse monitoring sensor, a preparation method, a pulse monitoring device and a system. Background technique [0002] Pulse is one of the important physiological parameters of the human body. It carries rich physiological and pathological information and has important physiological and diagnostic reference values. For example, the health status of the human heart, liver and gallbladder, and kidneys can be analyzed according to the pulse. [0003] With the gradual improvement of living standards, people are increasingly aware of the importance of health. Therefore, more and more users (such as the elderly and people with poor heart function) are eager for long-term effective medical monitoring. For some long-term People suffering from heart disease or the elderly who have been bedridden for a long time need real-time monitoring of some of their important vital signs (such a...
