홈페이지논문 초록 (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.
