Figure 7. Miniature piezoelectric tactile sensors for catheters. (A) A tactile sensor based on a PVDF film (left part) and its output voltage with respect to applied load (right plot)[64]. (B) A pressure sensor based on PVDF-TrFE copolymer film (left part) and its output voltage with respect to applied pressure (right plot)[13]. PVDF: Polyvinylidene fluoride.
