A Movable Electrode Triboelectric Nanogenerator Fabricated Using a Pencil Lead for Self‐Powered Locating Collision

The configurations of triboelectric nanogenerators (TENGs) are usually determined by their specific applications. The immobility of triboelectrodes limits the TENGs’ possible application in dynamic sensing. A subtle novel TENG composed of a movable pencil lead electrode is reported herein. The electricity can be extracted from the pencil lead, by touching an arch‐shaped unit, irrespective of whether the touched surface is the polymer layer or metal foil. It is found that the TENG device can deliver the maximal voltage of 2.37 V at the vibration frequency of 8 Hz. Moreover, due to the high sensitivity to collision/pressure, a sensor array system made of four TENG units is constructed to demonstrate the potential locating application. With the assistance of a self‐made testing program, the TENG array illustrates the capacity of self‐powered locating collisions that is independent of external power sources. Herein, not only TENG‐based devices’ diversity is promoted but also a new active locating route that greatly boosts the development of intelligent interaction is presented.
