Figure 6. Miniature supercapacitive tactile sensor for catheters. (A) A supercapacitive pressure sensor based on a solid electrolyte (left part) and its response sensing signal curve in the in-vitro test with a cuff pressure of 81.6 cmH2O (right plot)[63]. (B) An array of distributed iontronic force sensor (left part) and its capacitance responses to the force inside the extracted sheep urethra (right plot)[14].
