Hydrogel for application in soft robotics

A soft connection mechanism, unlike existing rigid mechanisms. Simple assembly, requiring no screws or other anchoring elements; contact alone allows assembly. It withstands high loads, unlike other similar contact-based adhesion mechanisms such as those based on magnets. It does not require external power like heat-activated or electro-adhesive adhesives. It is reversible, unlike most glues. Disassembly is done with just water, without the need for complicated procedures like most existing ones. The material is also recyclable and reusable.
