Abstract
The disclosure relates to a temperature sensitive system. The system includes a powder, a detector, a first electrode, a second electrode and an actuator. The powder, the detector, the first electrode, the second electrode and the actuator are connected to form a loop circuit. The actuator can deform in response to temperature change so that the circuit to be on or off. The detector is connected to the actuator in parallel or in series and configured to show the current change of the loop circuit to the user. The actuator includes a carbon nanotube layer and a vanadium dioxide layer (VO2) layer stacked with each other. Because the drastic, reversible phase transition of VO2, the actuator has giant deformation amplitude and fast response and the temperature sensitive system has high sensitivity.
