▎ 摘　　要

NOVELTY - The sensor has a base (1) which is provided with a hanging hole (2). A graphene nanometer wall is laid under the base. The graphene nanowall is connected to a polymer force sensitive film (3). The bottom of the polymer force sensitive film is connected with a pressure-sensitive bump (4). The pressure-sensitive bumps are arranged corresponding to the positions of the hanging holes. The graphene nanowalls are periodically provided with patterned strips (5). The graphene nanowall patterned layer is provided with a micron or nano-fold structure. USE - Pulse wave sensor of ambulatory blood pressure monitoring wearable device (claimed). ADVANTAGE - The radial artery pulse wave is effectively captured. The interference signal is shielded and pulse wave feature value is accurately extracted. The extraction precision of the wrist pulse wave is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method of manufacturing a pulse wave sensor; (2) an ambulatory blood pressure monitoring wearable device; and (3) an ambulatory blood pressure monitoring method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the pulse wave sensor of ambulatory blood pressure monitoring wearable device.
