A triboelectric generator is disclosed. The triboelectric generator according to an embodiment of the present disclosure includes a flexible electrode part comprising a first and a second dielectric layer, and at least one metal layer; and a fixed electrode part spaced apart from both sides of the flexible electrode part, and comprising a first and a second electrode connected to each other, wherein the flexible electrode part generates triboelectrification based on contact and non-contact by a fluid flow, and an electric charge moves through the metal layer, thereby effectively moving electric charges generated by triboelectrification, and increasing the friction frequency to enhance power generation efficiency.

The present invention provides a method of manufacturing a hydrogen sensor and a hydrogen sensor manufactured thereby. Specifically, the method according to the present invention includes a step of forming a self-assembled single layer on a stamp substrate provided with nanoline-patterned uneven parts; a step of depositing a metal thin film layer on the self-assembled single layer; a step of disposing the stamp substrate on a flexible sensor substrate so that a polymer layer formed on the sensor substrate and the metal thin film layer deposited on the uneven parts are brought into contact with each other; a step of transferring a metal nanoribbon array having nanogaps to the sensor substrate by performing pressure and heat treatment on the stamp substrate and removing the stamp substrate; and a step of forming first and second electrodes on both ends of the transferred metal nanoribbon array.
