A Novel and Inexpensive Approach for Force Sensing Based on FSR Piezocapacitance Aimed at Hysteresis Error Reduction
Figure 4
Simulation of (a) current density (J) versus stress (σ) at loading forces (blue) and at unloading forces (green). (b) Resistance per unit area (RA) versus stress (σ) for the same situations. Equation (12) was considered for both simulations carried out with MATLAB R2014. Sensor invariant parameters presented in [31] were considered. They are stated in Table 1.
