From Design to Applications of Stimuli-Responsive Hydrogel Strain Sensors

Abstract

Development and fabrication of stimuli-responsive polymers into hydrogel strain sensors with high sensitivity and specificity to subtle changes in environmental stimuli have open the door for exploring the opportunities from fundamental materials design principles to emerging applications of electronic skins, health monitors, and human-machine interfaces. This review mainly summarizes recent progress, particularly over the past 5 years, on hydrogel strain sensors from different aspects, including materials designs, gelation/fabrication methods, stimuli-responsive principles, sensing performance, and some typical or interesting examples of these hydrogel sensors. Finally, current challenges and future perspectives of hydrogen strain sensors are also discussed to stimulate the more and better research in this emerging field.
