Triboelectric nanogenerators based on 3D porous structures for energy harvesting applications |
| 초록 |
We present a simple and cost-effective strategy to fabricate a vertical contact-separation mode of 3D porous material based triboelectric nanogenerator (TENG). It can be used to harvest energy from the friction in a repetitive vertical force. The unit component of TENG is consist of thin Al foil electrodes integrated with microstructured 3D foams such as Ni, Cu, and polyurethane (PU). They provide an advantageous tribo-surfaces specifically to increase the friction area to contact surfaces of the counter elastomer (i.e., polydimethylsiloxane, PDMS). The periodic contact/separation-induced triboelectric power generation from a single unit of the 3D porous structure-based TENG was up to 0.74 mW/m2 under a mild condition. Moreover, we applied our TENGs to micro-scale devices to prove the potential applications of our approach, 48 LEDs and capacitors operating. |
