The feasibility of energy harvesting from mouse click motions is experimentally and theoretically assessed. The \ufb01ngers wear a glove with a pocket for including the piezoelectric material. We model the energy harvesting system through the inverse kinematic framework of parallel joints in a \ufb01nger and the electromechanical coupling equations of the piezoelectric material. The model is validated through energy harvesting experiments in the robot and human \ufb01ngers with the systematically varying load resistance. We \ufb01nd that energy harvesting is maximized at the matched load resistance to the impedance of the piezoelectric material, and the harvested energy level is tens of nJ.<\/jats:p>","DOI":"10.3390\/s16071045","type":"journal-article","created":{"date-parts":[[2016,7,6]],"date-time":"2016-07-06T09:55:55Z","timestamp":1467798955000},"page":"1045","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["Flexible Piezoelectric Energy Harvesting from Mouse Click Motions"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0239-2469","authenticated-orcid":false,"given":"Youngsu","family":"Cha","sequence":"first","affiliation":[{"name":"Center for Robotics Research, Korea Institute of Science and Technology, Seoul 02792, Korea"}]},{"given":"Jin","family":"Hong","sequence":"additional","affiliation":[{"name":"Center for Robotics Research, Korea Institute of Science and Technology, Seoul 02792, Korea"},{"name":"School of Mechanical Engineering, Korea University, Seoul 02841, Korea"}]},{"given":"Jaemin","family":"Lee","sequence":"additional","affiliation":[{"name":"Center for Robotics Research, Korea Institute of Science and Technology, Seoul 02792, Korea"}]},{"given":"Jung-Min","family":"Park","sequence":"additional","affiliation":[{"name":"Center for Robotics Research, Korea Institute of Science and Technology, Seoul 02792, Korea"}]},{"given":"Keehoon","family":"Kim","sequence":"additional","affiliation":[{"name":"Center for Robotics Research, Korea Institute of Science and Technology, Seoul 02792, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2016,7,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11957","DOI":"10.3390\/s140711957","article-title":"Wearable electronics and smart textiles: A critical review","volume":"14","author":"Stoppa","year":"2014","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"5310","DOI":"10.1002\/adma.201400633","article-title":"Fiber-based wearable electronics: A review of materials, fabrication, devices, and applications","volume":"26","author":"Zeng","year":"2014","journal-title":"Adv.
