The NCSU scientists were particularly inspired by a 2013 paper by Korean researchers. And one of its remarkable attributes is that it works perfectly well underwater.” “We have created a device that can turn this type of mechanical motion into electricity. "Mechanical energy-such as the kinetic energy of wind, waves, body movement and vibrations from motors-is abundant," said co-author Michael Dickey, a chemical and bimolecular engineer at NCSU. The team thinks the new NCSU device holds promise for powering wearable devices, charging them spontaneously with no need for an external power source. It produces small amounts of electricity comparable to other energy-harvesting technologies, and it can also operate in water as well as air, according to the team's recent paper published in the journal Advanced Materials. Scientists at North Carolina State University have developed a flexible, stretchy energy-harvesting device solely out of biocompatible soft materials: liquid metal and soft polymers known as hydrogels.
