The device integrates a thin Shape Memory Polymer (SMP) membrane with a matrix of compliant carbon-silicone composite heaters, a 4-layer flexible PCB and a flexible fluidic chamber. The actuator yield is 99 %, the taxel pitch is 4 mm and the average displacement is 275 μm with a 225 mN holding force, allowing easy discrimination using the sense of fine touch. One line can be reconfigured and latched in 2.5 s; the entire array can be refreshed in under 1 min 30 s with our current drive circuit. The bistable nature of SMPs enables selective and independent actuator motion by judiciously synchronizing their local Joule heating with a global external pressure supply.","PeriodicalId":174774,"journal":{"name":"2017 19th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131954154","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}
