Abstract: | In this work, a sponge structure triboelectric nanogenerator (TENG) named as porous conductive polymer (PCP)‐TENG, is demonstrated. The measured volume charge density of PCP‐TENG is reached to 60 mC m?3 by utilizing wide inner surface of the sponge structure as contact surface. Moreover, the PCP‐TENG generates a continuous sinusoidal‐like alternative current. Notably, the PCP‐TENG can effectively harvest vibrational mechanical energy from various directions and amplitudes. With these characteristics, the PCP‐TENG can be implemented in a wide variety of settings, such as inside of a tire. It is confirmed that the PCP‐TENG generates electrical power for operating a commercial light‐emitting diode and a humidity sensor even under small deformation of the tire. |
