Figure 15. (A) Schematics of human skin and the interlocked multimodal sensor used for pressure and temperature sensing because of its structural advantages; (B) schematic illustration of the 3 × 3 device used to detect different objects with various temperatures and pressures: (i) 2 kPa at ΔT (temperature change) -30 °C, (ii) 1 kPa at room temperature, (iii) 2 kPa at ΔT 30 °C, (iv) 1kPa at ΔT -30 °C, and (v), (vi) 2 kPa at room temperature; (C) detected temperature; and (D) pressure profiles of objects i-vi by using the sensor array^[128].
