From: Stretchable Dual-Capacitor Multi-Sensor for Touch-Curvature-Pressure-Strain Sensing
Pressure, strain, and touch sensing data for dual-capacitor sensor. Schematic views showing the operation principles of dual-capacitor sensor for (a) pressure, (b) strain, and (c) touch sensing. The upper (ΔC 2) and lower (ΔC 1) capacitance changes as functions of applied (d) pressure, (e) strain, and (f) repeated finger touch motions.
