As one of the energy harvesting, triboelectric nanogenerator (TENG) has been developed due to low fabrication cost and high performance. However, it is known that there is a limit to the practical use of the technology due to the low output current compared to the output voltage. In order to solve the problem, here, we present a dual-mode TENG with hierarchically designed wrinkle patterns composed of poly(dimethylsiloxane) (PDMS) and silver electrode layers. Compared with TENG devices with a single operation mode, our device can be applied to dual operation mode that uses vertical contact-separation mode and contact-sliding mode, exhibiting a high output voltage and current. To gain high power density, a wrinkle pattern was prepared through ultraviolet(UV)/ozone surface treatment. Our dual mode TENG is a promising approach in the development of stretchable TENG for the potential applications including wearable devices and stretchable electronics.
