Thermistors, which are fabricated from semiconductor materials as well as metallic compositions, serve as fundamental components in temperature sensor systems.

# Bimetallic Sheet Temperature Sensing Technology The manufacturing process of bimetallic sheets involves the bonding of two distinct metal sheets that possess significantly different thermal expansion coefficients. This composite material structure forms the fundamental basis for temperature-sensitive applications across various industrial and household domains. The specific configuration designates the upper metal layer to maintain a higher thermal expansion coefficient in comparison to the lower metal layer positioned beneath it. This deliberate material selection and layering arrangement creates the foundation for the thermomechanical response mechanism that follows.
(2) Working principle of electric iron
A bimetallic sheet temperature sensor is installed inside the electric iron as a fundamental component of the thermal management system. Under normal operating temperature conditions, the upper and lower contacts remain in direct contact with each other, establishing a complete electrical circuit. However, when the ambient temperature or the heating element temperature changes during iron operation, the bimetallic sheet undergoes a bending motion. This bending occurs due to the inherently different thermal expansion coefficients present between the upper metal layer and the lower metal layer that comprise the bimetallic sheet structure.

Temperature sensitive ferrite represents a specialized category of magnetic materials that exhibit ferromagnetic properties under ambient conditions. At room temperature, these ferrite-based materials demonstrate strong magnetic attraction and can be readily picked up or held by conventional magnets.

When the switch is pressed by hand, the permanent magnet and the temperature sensing magnet attract each other through their opposing magnetic poles. The mechanical interaction between these two magnetic components creates a holding force.

When the rice reaches its fully cooked state through the application of heat and moisture absorption mechanisms, a significant physical transformation occurs within the cooking vessel. The water that was initially added to facilitate the cooking process becomes progressively absorbed by the rice grains themselves, which causes the moisture level inside the pot to decrease substantially.
