©　2015,　Huazhong　University　of　Science　and　Technology.　All　right　reserved.Dielectric　elastomer-based　soft　machines　have　been　widely　applied　to　soft　robots,　energy　harvesters,　flexible　electronics,　etc.　Conventional　dielectric　elastomer　devices　are　actuated　by　non-transparent　carbon　paste　electrodes　or　electronic　conductors　made　of　hard　materials.　Instead,　the　stretchable　and　transparent　ionic　conductors,　with　two　soft　materials　combined,　open　the　door　to　a　unique　way　in　the　realization　of　soft　machines.　In　this　review,　the　recent　progress　on　dielectric　elastomer-based　soft　machines　actuated　by　ionic　conductors　is　summarized;　several　future　research　topics　and　perspectives　with　respect　to　this　area　are　also　suggested.
