Electronic　skin　is　an　important　means　through　which　robots　can　obtain　external　information.　A　novel　flexible　tactile　sensor　capable　of　simultaneously　detecting　the　contact　position　and　force　was　proposed　in　this　paper.　The　tactile　sensor　had　a　three-layer　structure.　The　upper　layer　was　a　specially　designed　conductive　film　based　on　indium-tin　oxide　polyethylene　terephthalate　(ITO-PET),　which　could　be　used　for　detecting　contact　position.　The　intermediate　layer　was　a　piezoresistive　film　used　as　the　force-sensitive　element.　The　lower　layer　was　made　of　fully　conductive　material　such　as　aluminum　foil　and　was　used　only　for　signal　output.　In　order　to　solve　the　inconsistencies　and　nonlinearity　of　the　piezoresistive　properties　for　large　areas,　a　Radial　Basis　Function　(RBF)　neural　network　was　used.　This　includes　input,　hidden,　and　output　layers.　The　input　layer　has　three　nodes　representing　position　coordinates,　X,　Y,　and　resistor,　R.　The　output　layer　has　one　node　representing　force,　F.　A　sensor　sample　was　fabricated　and　experiments　of　contact　position　and　force　detection　were　performed　on　the　sample.　The　results　showed　that　the　principal　function　of　the　tactile　sensor　was　feasible.　The　sensor　sample　exhibited　good　consistency　and　linearity.　The　tactile　sensor　has　only　five　lead　wires　and　can　provide　the　information　support　necessary　for　safe　human-computer　interactions.
