The　technique　of　electrical　impedance　tomography　(EIT)　has　been　recognized　as　a　promising　method　to　design　tactile　sensors　with　continuous　sensing　capability　over　a　large　area.　The　mechanism　of　electrical　impedance　tomography　allows　reconstructing　tactile　information　within　the　sensing　area　based　on　measurements　made　only　at　the　boundary.　However,　spatial　performance　of　EIT-based　tactile　sensors　has　demonstrated　location　dependency,　which　severely　affects　correct　interpretation　of　tactile　stimuli.　Here,　we　analyzed　the　effect　of　hyperparameter　on　the　spatial　performance,　in　terms　of　amplitude,　size,　position　error,　and　shape　deformation　in　the　reconstructed　images.　To　obtain　uniform　sensitivity　throughout　the　entire　sensing　area,　we　developed　an　intensity　scaling　method　to　correct　reconstructed　amplitudes　based　on　simulation　studies.　A　diagonal　scaling　matrix　was　developed　for　a　symmetric　circular　sensing　area,　and　the　scaling　value　were　constructed　according　to　the　radial　positions　of　the　finite　elements.　The　correction　method　was　further　evaluated　on　a　compliant　EIT-based　touch　sensor　made　of　polymer　filled　composites　with　underlying　paddings.　We　found　that　the　developed　method　effectively　produced　a　more　uniform　sensitivity　distribution,　and　improved　spatial　profiles　of　shape　deformation.　The　findings　shown　here　help　better　interpret　the　strength　information　of　tactile　stimuli　located　at　different　positions　of　large　area　EIT-based　sensors.
