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　C.　To　prove　the　practicability　of　the　noncontact　temperature　sensor,　a　3　×　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.　©　2021　by　the　authors.　Licensee　MDPI,　Basel,　Switzerland.
