Research of flexible sensor based on nanomaterial

A flexible sensor is a sensor made of flexible materials, generally composed of three layers: base layer, sensing layer, and packaging layer, can be widely used in medical electronics, biological monitoring, wearable electronics and other fields. Compared with traditional electronic devices, flexible electronics have cheap substrates and can be attached to curved surfaces to achieve sensing functions, which attract researchers in different fields. In recent years, the development of nanotechnology and polymer materials has greatly promoted the innovation of flexible electronics. This paper focuses on the application of nanotechnology in flexible sensing. Through horizontal induction and analysis of nanotechnologies in polymer -based sensors, hydrogel sensors, self-powered sensors and other sensors, suggestions for continuous detection and clinical treatment of sensors are put forward vertically. Achieving the structure and intrinsic flexibility of the flexible sensor substrate, deposition of the micro-circuit onto the substrate, encapsulation without breaking the ductility condition, maximizing its conductive, thermal and mechanical response, self-powered, degradability and other properties that meet human needs are all the focus of the flexible electronics discussion. In this paper, the structure, response and drug delivery of the flexible sensor will be analyzed and discussed from the Angle of material.
