▎ 摘　　要

NOVELTY - The device has a sensitive unit structure layer provided with a base body. A cavity (10) is formed in the base body for containing liquid medicine. A nozzle diffusion valve (11) is fixed with the cavity. The base body is provided with multiple convex structures that are pressed to extrude the liquid medicine in the cavity. Surfaces of the semi-spherical convex structures (13) are provided with a conductive film layer (15). An inter-digital electrode layer (20) is electrically connected with a control device. An inter-digital electrode is connected with the conductive film layer. A flexible film layer (30) is formed on the inter-digital electrode layer. USE - Medicine injection sensing and executing function featured wearable device. ADVANTAGE - The device is simple in structure and convenient to use, and integrates sensing and executing functions into one element by electromechanical liquid coupling, realizes miniaturization and portability of a flexible wearable device main body for health monitoring, improves sensing performance and real-time in-situ intelligent response capability, utilizes skin-similar micro-channel storage liquid as external pressure, and presses the convex structure, so that volume of the cavity structure is changed for realizing real time in situ intelligent response of external stimulus and intelligent injection medicine function.
