(PhysOrg.com) -- With the goal to enable small electronic devices to harvest their own energy, researchers have designed a device that can convert light and thermal energy into electricity. When exposed to visible light and/or heat (infrared) radiation, the 20-mm-long carbon-nanotube-film-based cantilever bends back and forth repeatedly, as long as the light and/or heat remains on. This is the first time that such cyclic bending behavior, which the scientists call "self-reciprocation," has been observed in this kind of system.
