Publication number: 20160294305Abstract: A triboelectric energy harvester comprises an electrode, a non-conductor, a first conductor, and a second conductor. The non-conductor is disposed on the electrode. The first conductor is disposed on the non-conductor. The second conductor frictionally contacts the first conductor. The frictional contact between the first and second conductors creates triboelectric energy.Type: ApplicationFiled: April 4, 2016Publication date: October 6, 2016Applicant: RESEARCH & BUSINESS FOUNDATION SUNGKYUNKWAN UNIVER SITYInventors: Sang Woo KIM, Sung Soo KWAK, Sang Hyun KIM, Seong Su KIM, Tae Yun KIM, Tae Ho KIM, Wan Chul SEUNG, Han Jun RYU, Hong Joon YOON, Jeong-Hwan LEE, Ju-Hyuck LEE
