▎ 摘　　要

NOVELTY - The system has a wearable base body provided with an outer shell body (1), in which a bottom surface of the outer shell body is provided with two wrist belts (2). Three groups of a graphene micro-strain sensor (4) are independently fixed in the outer shell body. The graphene micro-strain sensor detects characteristic information of a pulse wave. A surface of a flexible substrate (9) is provided with four graphene resistance wires to form a Wheatstone bridge. A circuit module provides power to the graphene micro-strain sensor, an ultrasonic transducer and a background noise sensor. USE - Pressure sensor based pulse diagnosis system. ADVANTAGE - Satisfies the frequency characteristic of the pulse signal with the broadband characteristic, and accurately and reliably obtains the voltage change value and human pulse signal. DESCRIPTION OF DRAWING(S) - The drawing shows the perspective view of the structure of a sensor. Outer shell body (1) Wrist belts (2) Graphene micro-strain sensor (4) Lead (6) Flexible substrate (9)
