Abstract
Provided is a self-powered pressure sensor which may show excellent pressure sensitivity by significantly improving transfer efficiency of charges generated by triboelectrification, the sensor including: a first electrode; a first triboelectrification unit positioned on the first electrode; a second triboelectrification unit including a pattern on which a microstructure is repeatedly positioned, the microstructure being reversibly in contact with or separated from the first triboelectrification unit by a physical external force, and having at least one surface in contact with the first triboelectrification unit to induce a change in a contact area; and a second electrode positioned inside the second triboelectrification unit and conformally positioned on a surface of the microstructure, wherein the first electrode and the second electrode are geometrically asymmetric to each other.
