Stretchable Hybrid Material Harnesses Friction Energy

Stretchable Hybrid Material Harnesses Friction Energy
Jun-06-17
An innovative new hybrid material able to harvest static electricity and provide tactile sensing could open the door to self-powered soft robots.

The new material, from the Georgia Institute of Technology, is an evolution of the team’s previous TENGs (triboelectric nanogenerators) technology. The new devices, called STENGs (skin-like triboelectric nanogenerators), are much more flexible than their predecessors. The STENGs harvest electricity from friction like TENGs, but do so by using an ionic hydrogel as the electrode and an elastomer as the electrification layer. This allows the material to be stretched up to 300 percent its length, while also being highly transparent and resistant to high temperatures.
