This　paper　presents　a　new　microactuator　using　a　phase　change　material　(PCM)　composite　with　induction　heating.　The　PCM　composite　is　consisting　of　paraffin　wax,　expanded　graphite　and　nickel　particle,　which　was　used　as　an　electrical　conductive　phase　change　material　with　improved　magnetic　permeability.　Expanded　graphite　was　used　as　an　electrical　conductive　porous　matrix　absorbed　with　paraffin　wax　and　nickel　particle.　This　work　relies　on　induction　heating　generated　in　the　PCM　composite　with　eddy　current,　rather　than　using　external　resistive　heater.　Experiments　show　that　about　140　mu　m　actuation　height　was　realized　in　5　s　with　the　input　power　of　1.42　W　at　excitation　frequency　of　1　kHz.　Since　an　induction　heating　method　is　adopted　with　electrical　conductive　PCM　composite,　which　means　the　new　microactuator　has　no　wire　or　electrodes　to　connect　with　the　conductive　PCM　composite.　The　new　PCM-composite-based　microactuator　has　some　advantages,　such　as　ease　of　fabrication,　small-sized,　low　cost,　and　eases　of　integration　into　Micro-Electro-Mechanical　Systems　(MEMS).　(C)　2018　Elsevier　B.V.　All　rights　reserved.
