With　the　development　of　the　economy　and　science,　information　technology　has　become　increasingly　integrated　into　modern　life,　making　information　encryption　crucial.　The　molecular　arrangement　of　cholesteric　liquid　crystals　(CLCs)　exhibits　a　unique　helical　structure,　which　provides　excellent　bistability.　This　molecular　arrangement　can　be　changed　under　the　action　of　an　electric　field,　consequently　changing　the　transmittance　of　light.　The　triboelectric　nanogenerator　(TENG)　is　a　novel　energy-harvesting　system　that　can　convert　mechanical　energy　into　electrical　energy　to　power　small　devices.　In　this　research,　the　optical　properties　of　a　CLC　and　the　energy　independence　of　a　TENG　were　utilized　to　support　an　information　encryption　system　for　data　security,　and　in　this　paper,　a　feather-based,　horizontal,　sliding　TENG　that　offers　a　voltage　range　adjustable　between　30　and　300　V　to　facilitate　switching　between　the　planar　and　the　focal　cone　textures　of　CLCs　is　proposed.　Moreover,　when　a　self-powered　CLC　was　combined　with　a　convolutional　neural　network,　the　accuracy　of　message　transmission　reached　more　than　98　%;　thus,　a　message　encryption　transmission　system　with　good　portability　and　low　cost　was　realized.　©　2024
