Tactile　sensor　as　core　component　of　robotic　haptics　enables　intelligent　perception　of　external　environment　for　smart　robot.　However,　it　is　a　critical　challenge　to　realize　simultaneously　high-sensitivity　pressure　sensing　and　high-resolution　tactile　imaging　of　tactile　sensor.　Herein,　a　hierarchical　hybrid　tactile　sensor　array　(HTSA),　which　is　fabricated　by　vertically　integrating　top　arrayed　TENG　layer　and　bottom　arrayed　capacitive　pressure　sensor　layer,　is　developed　to　achieve　simultaneous　pressure　sensing　and　tactile　imaging　for　tactile　pattern　recognition.　The　capacitive　pressure　sensor　array　(8　x　8)　can　realize　pressure　sensing　with　a　sensitivity　of　238.73　kPa(-1).　Meanwhile,　the　TENG-based　tactile　sensing　array　enables　high-resolution　tactile　imaging　of　handwritten　Chinese　characters.　More　importantly,　the　HTSA-based　tactile　pattern　recognition　system　(H-TPRS)　is　developed　to　achieve　accurate　user　signature　authentication.　Based　on　handwriting　behavior　characteristics,　an　accuracy　of　97.3%　of　tactile　pattern　recognition　is　achieved　in　identifying　the　different-user　handwriting　identical　letters　under　assistance　of　convolutional　neural　network.　Consequently,　the　H-TPRS　can　achieve　high-sensitivity　pressure　sensing　and　high-resolution　tactile　imaging　of　Chinese　characters　for　user　authentication,　which　demonstrates　potential　application　in　the　field　of　intelligent　tactile　perception.
