Abstract
A flexible triboelectric nanogenerator (TENG) has attracted much attention due to its environmentally friendly, practical, and cost-producing advantages. Flexible electrodes are required to fabricate a fully flexible TENG device. Electrical properties of porous polydimethylsiloxane (PDMS) sponge-based flexible TENGs with two types of flexible electrodes including copper and carbon nanotube (CNT)-PDMS were compared. Output voltages and maximum power densities of the PDMS sponge-based flexible TENGs with the copper and CNT-PDMS electrodes were compared. The voltage and the power density of the PDMS sponge-based flexible TENG with the CNT-PDMS electrodes were shown to be improved compared to the copper electrodes. The output voltage and the maximum power density of the PDMS sponge-based flexible TENG with the CNT-PDMS electrodes increased 4 times and 7 times, respectively, compared to the PDMS sponge-based flexible TENG with the copper electrodes because electrical conductivity is higher and electricity more stably flows in CNTs than in copper.
