Researchers have created a nanostructured gel that can act as a synthetic muscle. The material reacts to chemical changes in its environment by expanding or contracting.
The gel consists of a polyacid matrix containing nanoscopic hydrophobic domains. The material is formed by self-assembly from a triblock copolymer.
Testing the synthetic muscle by using it to bend a soft cantilever revealed that it produced a power per unit mass… read more
