Abstract Scope |
Robust adhesives that strongly bond while also controllably releasing in wet or underwater environments are required in diverse fields including bio-medical applications, wearable electronics, and soft robotics. Nature can provide inspiration for these challenging adhesion scenarios. For example, the octopus utilizes controllable adhesives with intricately embedded sensors and control schemes to grasp and release underwater objects. Here, we couple switchable, octopus-inspired adhesives with embedded sensing, processing, and control for robust underwater manipulation. Adhesion strength is switched over 1000× from the ON to OFF state in <50 ms over many cycles with an actively controlled membrane. Systematic design of adhesive geometry enables adhesion to nonideal surfaces with low preload and independent control of adhesive strength and toughness for strong and reliable attachment with easy release. These capabilities are demonstrated with a wearable glove where an array of adhesives and sensors creates a biomimetic adhesive skin to manipulate diverse underwater objects. |
