Block Diagram of experimental characterization. The source of force in this experiment is a double acting cylinder controlled by the represented pneumatic circuit (1). The cylinder is fixed to a mechanical setup (2) where the silicone structure (3) is placed. The two variables; force acquired by the force sensor (4) and change in bioimpedance acquired in the form of change of output frequency of SRCO circuit (5), undergo two signal conditioning circuits (6) before being acquired by the data acquisition circuit (7).
