Embodiment 2
[0040] Example 2 A method for detecting pressure, temperature and humidity
[0041] This embodiment adopts Embodiment 1 to realize, including the following steps carried out in sequence:
[0042] 1. Apply a DC current signal / DC voltage signal / square wave signal between positive and negative phases to the third electrode and the sixth electrode respectively, and apply an AC current signal / AC voltage signal to both ends of the third electrode and the sixth electrode;
[0043]2. When the pressure on the outer surface of the artificial skin corresponding to the first electrode / second electrode / fourth electrode / fifth electrode changes, charges are generated on the surface of the piezoelectric material layer, and when the artificial skin corresponding to the third electrode / sixth electrode When the temperature of the outer surface of the skin changes, the resistivity of the third electrode / sixth electrode changes, thereby causing the resistance value of the third electrode / sixth ele...
Embodiment 3
[0045] Embodiment 3 A method for adjusting temperature
[0046] This embodiment adopts Embodiment 1 to realize, comprising the following steps:
[0047] (1) applying a DC voltage signal across the first electrode and the second electrode, and applying a DC voltage signal across the fourth electrode and the fifth electrode;
[0048] (2) Adjust the voltage values at both ends of the first electrode and the second electrode, and charge accumulation occurs in the corresponding N-polarized semiconductor material layer 1 and P-polarized semiconductor material layer 2, which in turn causes the temperature value of the third electrode to change. Corresponding changes; adjust the voltage values across the fourth electrode and the fifth electrode, and charge accumulation occurs in the corresponding N-polarized semiconductor material layer 1 and P-polarized semiconductor material layer 2, thereby causing the temperature value of the sixth electrode Changes accordingly.
