Abstract

The invention discloses a compressible wearable finger pulse measuring device, which comprises a flexible graphene pressure detector, a signal processing system, a man-machine interaction system and a power system. Three-dimensional graphene sponge serves as the flexible graphene pressure detector. The signal processing system performs amplification, shaping, filtering and the like on collected weak signals to inhibit external interference and increase the signal-to-noise ratio. The man-machine interaction system displays a measuring result to a user. The power system provides a stable and low-noise power source for the device. By the compressible wearable finger pulse measuring device, problems of accuracy and instantaneity in real-time pulse and heartbeat monitoring are solved.

Description

technical field [0001] The invention relates to the technical field of wearable measuring devices, in particular to a wearable finger pulse measuring device based on a compressible three-dimensional graphene pressure detector. Background technique [0002] Modern people are more and more concerned about their health, hoping to know their physical condition in real time. There are many devices for measuring heartbeat and pulse on the market. Many people like to wear wristbands while running to simultaneously detect their heartbeat level. However, its measurement effect is not accurate, and sometimes it is very different. In this way, the functions of accurate real-time monitoring and post-event analysis cannot be achieved. The reason for the inaccurate measurement is that the piezoelectric sensors used in current devices are all crystalline materials, which cannot adhere to the skin. Contents of the invention [0003] The purpose of the present invention is to solve the ...
