Spiders use adhesive, stretchable, and translucent webs to hunt their prey. However, spiders have struggled to maintain stable capture capability because the strong adhesion force of the web inevitably causes to contamination. To overcome these challenges, spiders have evolved their own unique strategies, which utilize web themselves to sense prey and clean contaminants. Here, we present ionic spiderwebs (ISWs) to emulate the outstanding hunting strategies used by spiders, including capturing, sensing, and cleaning, with a pair of threads that were controlled by a single input control based on electrostatics. An ISW completed a consecutive mission consisting of cleaning contamination on itself, sensing an approaching target, capturing targets and releasing them. The ISWs show the importance of learning from nature and pushing the boundary of soft robotics in attempts to possess multi-functions in a single platform. |
