Harvesting Electricity: Triboelectric Generators Capture Wasted Power

Image shows how power is generated by sliding two materials together and then creating a gap between them. This effect could be used to produce power for portable electronic devices. (Credit: Inertia Films)

Growing up in the Chinese countryside, Zhong Lin (Z.L.) Wang aspired to follow in his father’s footsteps at a local factory.

Researchers develop world’s thinnest electric generator

Researchers from the Georgia Institute of Technology and Columbia Engineering have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2). Shown is a sample of the material that could be the basis for unique electric generator and mechanosensation devices that are optically transparent, very light, and extremely bendable and stretchable.

Two-Stage Power Management System Boosts Energy-Harvesting Efficiency

Triboelectric nanogenerators use a combination of the triboelectric effect and electrostatic induction to generate small amounts of electrical power from mechanical motions such as rotation, sliding or vibration. (Credit: Zhong Lin Wang Laboratory)
