一种用于植物生长无损监测的可穿戴应变传感器
A Wearable Strain Sensor for Non-destructive Monitoring of Plant Growth
摘要
Abstract
Healthy plant growth information is a key factor determining crop quality,food security,and agricultural productivity.As an emerging monitoring tool,plant wearable sensors,with their stretchability,flexibility,high spatiotemporal resolution,and good biocompatibility,hold the potential for continuous monitoring of plant growth information.This study reports a simple and low-cost fabrication method for patterning transparent conductive materials and transferring them onto flexible substrates.Based on this method,a plant wearable sensor was fabricated by combining poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS)and polydimethylsiloxane(PDMS),enabling in situ,non-destructive,and continuous detection of plant growth.The sensor features transparency,stretchability(0％-50％),high stability(relative resistance change fluctuation＜2％over 96 h),and high biocompatibility.It can detect minute changes as small as 0.75％and remains stable after 2 000 s of stretching and releasing cycles.Based on in vivo experimental observations,this study successfully achieved real-time monitoring of the growth dynamics of watermelon(Citrullus lanatus)seedling leaves and accurately captured a cumulative increase of 3 mm in leaf length.This study provides a new method for the non-destructive monitoring of plant growth information,aiming to offer a reference for plant information acquisition.关键词
