Some polymers can expand and contract — acting like artificial muscles — but only when stimulated by high voltages. Researchers in ACS Applied Materials & Interfaces report a series of thin, elastic films that respond to lower electrical charges, representing a step toward artificial muscles.

Resilient bug-sized robots keep flying even after wing damage
Inspired by the hardiness of bumblebees, MIT researchers have developed repair techniques that enable a bug-sized aerial robot to sustain severe damage to the actuators, or artificial muscles, that power its wings — but to still fly effectively.
NAU mechanical engineers develop new high-performance artificial muscle technology
The study, led by professors Michael Shafer and Heidi Feigenbaum, demonstrates that ‘cavatappi’ artificial muscles, which are based on the shape of Italian pasta, exhibit specific work and power metrics 10 and five times higher than human skeletal muscles, respectively, and up to about 45 percent efficiency.
