A　new　thermal　insulation　microactuator　for　Braille　display　using　a　phase　change　material　(PCM)　composite　with　induction　heating　is　proposed.　The　PCM　composite　is　prepared　by　fully　mixing　paraffin　with　multi-walled　carbon　nanotubes　(MWCNTs),　which　is　mainly　used　as　both　electrically　and　thermally　conductive　enhancer.　As　a　result　of　that,　the　PCM　composite　is　conductive　and　a　wireless　induction　heating　can　be　realized　with　the　paraffin　composite,　which　avoids　the　connection　of　wires　from　the　inner　chamber　with　a　relatively　simple　fabrication　process.　In　order　to　prevent　the　penetration　of　the　paraffin　from　the　elastic　film,　a　solvent-resistant　TPU　diaphragm　is　adopted　to　seal　the　PCM　chamber.　In　addition,　thermal　insulation　between　the　higher　temperature　of　PCM　and　the　finger　contact　is　designed　by　adding　the　PDMS　diaphragm　with　PDMS　pins.　When　the　input　power　is　1.29W　at　AC　frequency　of　1kHz,　the　actuation　height　of　the　Braille　dot　reaches　259　mu　m　within　7s.　The　microactuator　for　Braille　display　presented　in　this　paper　has　the　advantages　of　short　response　time,　thermal　isolation,　simple　fabrication,　small　size　and　low　cost.
