The particular case of energy harvesting on road pavements is a very recent area of research, with different technologies having been developed for this purpose. However, none of them have presented high conversion efficiency rates nor technical or economic viability. Looking at other renewable energy technologies, the inclusion of not only electrical but also in some cases mechanical energy storage units has led to an increase in global efficiency and, consequently, economic viability. This paper deals with the technical study of the integration of mechanical energy storage systems in a road pavement energy harvesting hydraulic device with mechanical actuation in order to evaluate the impact on global efficiency. The main goal is to quantify the efficiency of the energy storage and the overall efficiency of the system, including the harvesting, transmission, and conversion efficiency rate, comparing it to scenarios where no storage system is used. Finally, the conclusions on the performance of each system are presented.<\/jats:p>","DOI":"10.1063\/1.4999513","type":"journal-article","created":{"date-parts":[[2017,8,21]],"date-time":"2017-08-21T12:28:11Z","timestamp":1503318491000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":4,"title":["Integration of a mechanical energy storage system in a road pavement energy harvesting hydraulic device with mechanical actuation"],"prefix":"10.1063","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5044-7407","authenticated-orcid":false,"given":"Francisco","family":"Duarte","sequence":"first","affiliation":[{"name":"Pavement Mechanics Laboratory, Research Center for Territory, Transports and Environment, Department of Civil Engineering, University of Coimbra 1 , Rua Lu\u00eds Reis Santos, 3030-788 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1681-0759","authenticated-orcid":false,"given":"Adelino","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Pavement Mechanics Laboratory, Research Center for Territory, Transports and Environment, Department of Civil Engineering, University of Coimbra 1 , Rua Lu\u00eds Reis Santos, 3030-788 Coimbra, Portugal"}]},{"given":"Paulo","family":"Fael","sequence":"additional","affiliation":[{"name":"Department of Electromechanical Engineering, University of Beira Interior 2 , Cal\u00e7ada Fonte do Lameiro, 6200-001 Covilh\u00e3, Portugal"}]}],"member":"317","published-online":{"date-parts":[[2017,8,21]]},"reference":[{"volume-title":"A Review on Energy Harvesting From Roads","year":"2012","key":"2023063015263723900_c1"},{"key":"2023063015263723900_c2","doi-asserted-by":"crossref","DOI":"10.1201\/b10778","volume-title":"Large Energy Storage Systems Handbook","author":"Barnes","year":"2011"},{"edition":"4th ed.","volume-title":"Electric Machines Fundamentals","year":"2004","key":"2023063015263723900_c4"},{"issue":"3","key":"2023063015263723900_c5","doi-asserted-by":"publisher","first-page":"291","DOI":"10.1016\/j.pnsc.2008.07.014","article-title":"Progress in electrical energy storage system: A critical review","volume":"19","year":"2009","journal-title":"Prog.
