Organosilica materials made from monomers including at least a source of silica that is reactive to polymerize, optionally in combination with at least one additional cyclic monomer. Methods for making such organosilica materials are also described herein.

A method for producing a silicone-based adhesive is disclosed. The method comprises: (1) applying a silicone composition (I) to one surface of a peelable substrate, and then forming a silicone layer (I) by curing or drying the silicone composition (I); and (2) applying a silicone composition (II) to a surface of the silicone layer (I), and then forming the silicone-based adhesive by curing the silicone composition (II). The silicone composition (I) contains a silicone resin. The silicone composition (II) either does not contain the silicone resin or if contained, its content amount is lower than that in the silicone composition (I). The method is useful for producing a silicone-based adhesive with low peel resistance from a peelable substrate even with a low modulus.

Soft-matter technologies are essential for emerging applications in wearable computing, human-machine interaction, and soft robotics. However, as these technologies gain adoption in society and interact with unstructured environments, material and structure damage becomes inevitable. A robotic material that mimics soft tissues found in biological systems may be used to identify, compute, and respond to damage. This material includes liquid metal droplets dispersed in soft elastomers that rupture when damaged to create electrically conductive pathways that are identified with a soft active-matrix grid. These technologies may be used to autonomously identify damage, calculate severity, and respond to prevent failure within robotic systems.
