Imagine having a tool that allows you to grip and lift objects with precision, regardless of their shape or surface. This is exactly what researchers at Virginia Tech set out to achieve in their latest project.
The team, led by soft materials engineer Michael Bartlett, developed a groundbreaking adhesive technology inspired by the suction cups of an octopus. By combining a curved rubber stalk with a silicone-based adhesive membrane, they were able to create a versatile and controlled suction system.
Through a series of experiments, Bartlett and his colleagues demonstrated the adhesive’s ability to grip rough and complex objects like shells and rocks. They even successfully assembled underwater stone towers known as cairns, a task usually performed by hand.
According to physicist Andrew Croll from North Dakota State University, “Switchable adhesives are the holy grail of adhesion technologies.” The team’s innovative suction technology offers a level of control and stability that surpasses existing adhesives.

Looking ahead, Bartlett envisions a wide range of applications for their adhesive technology. From underwater welding to surgical procedures, the possibilities are endless. This tool could revolutionize assistive devices, allowing users to manipulate objects with ease, regardless of their shape or moisture levels.
While the technology may still need some refinements in terms of size and durability, it holds tremendous potential for everyday use. With further development, this innovative adhesive could become a staple in every household’s toolbox.
