During　social　interactions,　people　can　obtain　a　great　deal　of　important　information　from　their　tactile　senses　to　improve　their　relationship　with　their　surroundings.　The　development　of　similar　capabilities　in　robots　will　contribute　to　the　success　of　intuitive　human-robot　interaction　in　the　future.　In　this　paper,　a　tactile　sensing　method　based　on　the　principle　of　electrical　impedance　tomography　(EIT)　is　introduced,　which　with　the　help　of　EIT　technology　and　combined　with　the　flexible　piezoresistive　material　Velostat,　thin,　lightweight,　stretchable,　and　flexible　skin　can　be　designed　for　robots,　and　at　the　same　time,　information　about　the　touch　position,　duration,　and　intensity　can　be　acquired,　and　the　image　reconstruction　is　carried　out　using　a　dual　finite　element　model,　and　the　experimental　results　show　that　based　on　the　flexible　The　experimental　results　show　that　the　EIT　tactile　sensing　technology　based　on　the　flexible　material　Velostat　can　be　applied　to　robotic　flexible　skin　applications.　©　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.　2024.
