The　trend　of　mobile　Internet　requires　portable　and　wearable　devices　as　bio-device　interfaces.　Electric　field　control　of　magnetism　is　a　promising　approach　to　achieve　compact,　light-weight,　and　energy-efficient　wearable　devices.　Within　a　flexible　sandwich　heterostructure,　perpendicular　magnetic　anisotropy　switching　was　achieved　via　low-voltage　gating　control　of　an　ionic　gel　in　mica/Ta/(Pt/Co)(x)/Pt/ionic　gel/Pt,　where　(Pt/Co)(x)　acted　as　a　functional　layer.　By　conducting　in　situ　VSM,　EPR,　and　MOKE　measurements,　a　1098　Oe　magnetic　anisotropy　field　change　was　determined　at　the　bending　state　with　tensile　strain,　corresponding　to　a　magnetic　anisotropy　energy　change　of　3.16　x　10(5)　J/m(3)　and　a　giant　voltage　tunability　coefficient　of　0.79　X　10(5)　J/m(3).V.　The　low　voltage　and　strain　dual　control　of　magnetism　on　mica　substrates　enables　tunable　flexible　spintronic　devices　with　an　increased　degree　of　manipulation.
