▎ 摘　　要

NOVELTY - The device has a main body (1) and a wrist belt connected with the main body. A preset area of a wearing surface of the wrist belt is provided with multiple pressure sensors (3) arranged in an array, Where the multiple pressure sensor is used for collecting a pulse data of a user. An outer side of the main body is provided with a conductive joint, and the conductive joint is connected with the storage unit set in the main body. A dielectric layer is made of a composite of graphene, carbon nanotube, silver nanowire, and copper nanowire, and a polymer elastomer. A high molecular polymer elastomer comprises one of styrene block copolymer, thermoplastic polyurethane, polyolefin elastomer, polystyrene elastomer, polyamide elastomer and silicone rubber. USE - Wearable device for detecting three-dimensional pulse information. ADVANTAGE - The device has a main body and a wrist belt that is connected with a main body, where preset area of a wearing surface of the wrist belt is provided with multiple pressure sensors that are arranged in an array, and thus enables to accurately and comprehensively express a traditional pulse condition characteristic. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a wearable device for detecting three-dimensional pulse information. 1Main body 2Wrist band 3Pressure sensors
