Bringing triboelectric nanogenerators into classrooms

Triboelectric nanogenerators (TENGs), which capture and convert mechanical movement into electricity, have manifold potential applications. This emerging technology may one day power smartphones, wearable medical devices, environmental monitoring equipment, and other small electronic devices. On a larger scale, they could even be embedded into roadways to convert mechanical energy from passing vehicles into electrical power. TENGs have already been shown to function as microphones and loudspeakers, demonstrating their versatility.

However, these cutting-edge devices are more accessible than they may seem. In an effort to encourage physics teachers to include TENGs in their classrooms and curriculums, Christopher Chiaverina introduced these devices and provided step-by-step instructions about how to easily build them with common household supplies: paper, aluminum foil, transparent packing tape, and two wire leads.
