Abstract | What if "every breath you take, every move you make" (Sting 1983) could be harnessed to produce renewable energy? Triboelectric nanogenerators (TENGs) are state-of-the-art devices researchers are studying to do just that--convert kinetic energy into electrical energy at the source (Saurabh Rathore 2018). This type of electrical energy is called triboelectricity, commonly experienced as static electricity, and is produced when two materials, such as a rubber balloon and human hair, come into contact, exchanging and separating charges, producing a voltage. TENGs create triboelectricity through the use of two materials, one that develops a positive charge and one that develops a negative charge. Triboelectricity is produced when the materials within the TENG are repeatedly brought into contact and separated. Typically, the kinetic energy from movement like walking or dancing is dissipated as heat and sound (Corrales, Chartier, and Devanathan 2005), but TENGs convert this kinetic energy into useful electricity that can power small electronics such as cell phones. This article details how students can build a simple, state-of-the-art, renewable energy device; experiment with circuits; and explore how scientists and engineers exploit surface-area-to-volume ratios to achieve desired results.
