Photostriction is strongly dependent on the the history of sample preparation, grain size and remanent polarization. Using PLZT(3/52/48) ceramics, a photodriven relay has been fabricated as a trial photostrictive actuator. This relay consists of an optomechanical bimorph-type actuator and a snap action switch. The relay response has been analyzed on the basis of the photostrictive material characteristics and the shape of the bimorph.","PeriodicalId":302681,"journal":{"name":"Sixth IEEE International Symposium on Applications of Ferroelectrics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122129805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
