Researchers have developed a series of thin, elastic films made from bottlebrush polymers that can act as artificial muscles, as reported in. These materials can potentially be used in soft robotic implants and artificial organs. Unlike current bottlebrush polymer films that require dangerously high voltages above 4,000 V, these new films respond to substantially lower electrical charges, as low as 800 V.
Whether wriggling your toes or lifting groceries, muscles in your body smoothly expand and contract. Some polymers can do the same thing — acting like artificial muscles — but only when stimulated by dangerously high voltages. Now, researchers inreport a series of thin, elastic films that respond to substantially lower electrical charges. The materials represent a step toward artificial muscles that could someday operate safely in medical devices.
The researchers synthesized a suite of bottlebrush polymers by reacting norbornene-grafted polydimethylsiloxane macromonomers and cross-linking the products by ultraviolet light. A 60-µm-thick material was the most electroactive, expanding more than previously reported elastomers, with an operating voltage of 1,000 V. And a circular actuator made out of that material expanded and contracted more than 10,000 times before degrading.
