Construction of Biomass-Based Sensors and Their Application in Human Health Monitoring
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.
