Conductive Hydrogel-based Flexible Electronic System:Innovative Experimental Design in Flexible Electronics
Conductive hydrogels amalgamate characteristics of both biomedical materials and conductive materials,finding applications in medical rehabilitation,motion monitoring,and human-machine interaction among others.To enhance the innovative awareness and experimental skills of undergraduate students majoring in flexible electronics,this experiment designs a conductive hydrogel crosslinked by nanogel materials.By exploring the initiator concentration and cross-linking mechanisms during the polymerization of co-polymeric hydrogels,the impact of material structural components on the durability and sensing performance of hydrogel-based flexible electronic devices were elucidated.Through taking part in this novel experimental design,undergraduates majored in flexible electronics can acquire key points on polymer emulsion polymerization,hydrogel synthesis,stress-strain sensing property characterization,gaining a deeper understanding of the influence of cross-linking agent structural design on material functionality.Additionally,this experiment developed a hydrogel based flexible and wearable sensing system based on hydrogel flexible electronic sensors.By integrating a smart glove capable of controlling a small car's movement and a hydrogel controller for computer game control,we tightly merge cutting-edge research with undergraduate experimental teaching tasks.This integration is beneficial in stimulating the research interest and innovative exploration spirit among undergraduates majoring in flexible electronics,materials,and electronic information.
