摘要
随着柔性电子设备不断发展,可穿戴式柔性传感器在人体健康监测、电子皮肤、智能机器等领域表现出巨大的发展潜力.生物质材料作为一种源于生物体的可再生资源,具有价格低廉、绿色环保、亲肤透气、生物相容性好等优点,已被作为可穿戴柔性传感器的基底进行大量研究.生物质基传感器由于融合了生物质材料与传感元件的优良特性,因此可作为人体健康监测领域的理想选择.本文综述了常见柔性传感器(应变、压力、温度、生物)的结构、组成及工作原理,然后详细介绍了不同生物质基传感器的特点及其应用,所涉及的生物质材料主要包括胶原蛋白、明胶、纤维素、壳聚糖、海藻酸钠以及丝素蛋白等.之后,对生物质基传感器在人体健康监测(如物理信号、化学信号、生物电信号、热信号监测)中的应用进行了概述.最后,结合目前所面临的应用现状,指出了生物质基传感器在人体健康监测应用方面所面临的挑战及未来发展方向.
Abstract
With the continuous development of flexible electronic devices in recent years,flexible wearable sensors show great potential for development in the fields of human health monitoring,electronic skin,and intelligent machines.Biomass materials,as a kind of renewable resource derived from living organisms with excellent characteristics such as inexpensive,green and,eco-friendly,skin-friendly and breathable,and good biocompatibility,have been heavily studied as the matrix of wearable,flexible sensors.Biomass-based sensors can be ideal for use in the field of human health monitoring because they combine the excellent properties of biomass materials with sensing elements.This paper first reviews the structure,composition and working principle of common flexible sensors(strain,pressure,temperature,biological).And then,the characteristics of different biomass-based sensors and their applications are described in detail.The biomass materials involved mainly include collagen,gelatine,cellulose,chitosan,sodium alginate,and silk protein.In addition,the applications of biomass-based sensors in human health monitoring(including physical signals,chemical signals,bioelectrical signals and thermal signals monitoring)are summarised.Finally,the challenges and future directions of biomass-based sensors and their applications in the field of human health monitoring are pointed out in light of the current status of the applications they are currently facing.
