To help solve these problems, we demonstrated two types of artificial muscles that convert the chemical energy of high — energy - density fuels to mechanical energy. (science.sciencemag.org)
By exploiting this continuous action, researchers believe the polymer film could either act as artificial muscles, or be used to generate electricity to power small devices. (treehugger.com)
One common approach to making artificial muscles uses materials called shape memory alloys, such as a mixture of nickel and titanium. (sciencemag.org)
