A Novel and Inexpensive Approach for Force Sensing Based on FSR Piezocapacitance Aimed at Hysteresis Error Reduction

Figure 8

(a) Resistance per unit area versus stress and (b) capacitance per unit area versus stress. Both graphs present considerable hysteresis due to the already-known hysteresis provided by s(σ). For (a), parameter values shown in Table 1 were considered.
