Figure 1: Illustrative schematic and electrical properties of MFSOTE devices.

(a–h) Schematic illustration of temperature–pressure (T–P) sensing mechanism: (a,b) pristine. (c,d) a temperature gradient (ΔT) is applied across a MFSOTE device. (e,f) a pressure is loaded. (g,h) loading of a coupled temperature and pressure stimuli. Graph (i,j) show the measured I–V curves of a MFSOTE device taken at various ΔT (i) and different loading pressure (j). The time delay (i,j) between the contact and the measurement of the electrical signal is 10 s.
