Flexible　sensors　have　attracted　extensive　attention　because　of　their　promising　applications　in　the　fields　of　health　monitoring,　intelligent　robots,　and　electronic　skin,　etc.　During　the　COVID-19　epidemic,　noncontact　control　of　public　equipment　such　as　elevators,　game　consoles,　and　doors　has　become　particularly　important,　as　it　can　effectively　reduce　the　risk　of　cross-infection.　In　this　work,　a　noncontact　flexible　temperature　sensor　is　prepared　via　a　simple　dip-drying　progress,　in　which　poly(3,4-ethylenedioxythiophene):poly(4-styrene　sulfonate)　(PEDOT:PSS)　and　printer　paper　served　as　the　sensing　material　and　the　flexible　substrate,　respectively.　We　combined　the　highly　sensitive　temperature-responsive　property　of　PEDOT:PSS　with　the　good　hygroscopicity　of　printer　paper.　The　prepared　sensor　shows　high　sensitivity　and　good　stability　in　noncontact　sensing　mode　within　the　temperature　range　of　20-50　degrees　C.　To　prove　the　practicability　of　the　noncontact　temperature　sensor,　a　3　x　2　sensing　array　is　prepared　as　a　noncontact　human-machine　interface　to　realize　the　interaction　between　player　and　＂Pound-A-Mole　game＂　and　a　Bluetooth　car.　These　two　demos　show　the　sensor　＇　s　ability　to　perceive　nearby　temperature　changes,　verifying　its　application　potential　as　a　noncontact　human-machine　interaction　interface.
