会议名称：2019 Materials Research Society Spring Meeting & Exhibit

会议时间：22-26 April 2019

会议地点：Phoenix, USA

会议简介：The Materials Research Society (MRS) was established in 1973 by a visionary group of scientists who shared the belief that their professional interests were broader in scope than existing single-discipline societies and that a new interdisciplinary organization was needed. Today MRS is a growing, vibrant member -driven organization of over 14,000 materials researchers from academia, industry, and government, and a recognized leader in the advancement of interdisciplinary materials research. Headquartered in Warrendale, Pennsylvania (USA), MRS membership now spans over 80 countries. The MRS Spring Meeting attracts nearly 5,000 attendees. For more information on the Materials Research Society, please check the MRS Web site at www.mrs.org. We look forward to working with you at the 2019 Spring Meeting and trust it will prove to be a scientifically stimulating experience.

Title: Friction Force Effect on the Electrical Output Performance of Sliding-mode Triboelectric Nanogenerator

Abstract: As a revolutionary energy harvesting technology, triboelecric nanogenerator (TENG) has attracted the worldwide attention for its distinguished properties and wide application as self-powered sensors since it was invented. A common challenge for sliding-mode TENG was surface friction induced materials abrasion and electrical output performance degradation in mechanical energy harvesting under long-term continuous work. Clarify the effect of friction force on the electrical output performance of sliding-mode TENG not only can improve its output performance but also provide a guideline in the structure design of TENG. In this work, a series of experiments were designed and conducted to reveal the effects of the friction force on the electrical output performance of three kinds of sliding-mode TENG, namely, metal-dielectric, semiconductor-dielectric and dielectric-dielectric. The results showed that the short-circuit output current and the open-circuit voltage of the metal-dielectric sliding-mode TENG increased with the increase of sliding friction force. More importantly, we found that with an excitation induced by friction force the short-circuit output current of the metal-dielectric sliding-mode TENG showed an inverse tendency compared with the short-circuit output current under a changeless friction force. In addition, it was found that a wave friction force has great benefit in enhancing the electrical output performance of metal-dielectric sliding-mode TENG. These findings not only reveal the effect of friction force on the electrical output performance of sliding-mode TENG but also provide a guideline for designing and optimizing the structure of TENG to efficiently harvesting mechanical energy.
