New paper on octopus-inspired adhesives with switchable attachment to challenging underwater surfaces.

It works on soft and rigid objects that are flat, rough, and even curved (think rocks, shells, and delicate gel beads)!

See it in Advanced Science

粘着テープにコの字型の切れ込みをたくさん入れると、一方の端からはものすごく剥がしにくくなる（もう一方から剥がすと普通に剥がれる）

粘着力が60倍もあがるのだそうだ

New paper on Electrically Conductive Liquid Metal Composite Adhesives.

This SofT integrated composite with tacK through liquid metal (STICK-LM) adhesive can reversibly bond soft electronics and robotics.

Metamaterial adhesives use non-linear cut architectures to control reverse crack propagation to tune adhesion. This mechanism works in a wide range of materials, substrates, and conditions. Cut features must be designed around a characteristic length.

[Michael Bartlett @SMSLaboratory]

We can specifically place the non-linear cuts to tune adhesion strength at any film location. A digital fabrication framework enables this and rapidly customizes adhesive characteristics with deterministic control.

[Michael Bartlett @SMSLaboratory]

We leverage both material and geometric mechanisms to span a spectrum of unique adhesives properties, from strong and extremely reversible to extremely strong with reversibility, including adhesives with strength/energy over 3000 N/m (J/m^2) that are also reusable and directional

New paper introducing metamaterial adhesives that achieve strong yet releasable adhesion.

Programmed cuts force cracks to propagate BACKWARDS for enhanced adhesion, while allowing normal, forward crack growth for easy release.

Congratulations to our group member Dohgyu for receiving this exciting award for his adhesion work!

[Michael Bartlett @SMSLaboratory]

Big thanks to @MarwaEldiwiny for the great discussion on shape morphing materials on the Soft Robotics Podcast! So much fun talking with you!

"Nature already has some great solutions, so our team looked to the natural world for ideas. The octopus became an obvious choice for inspiration," researcher Michael Bartlett said. 🐙
