Thermistors are devices used to measure temperature by responding to changes in heat. While thermistors themselves are simple, the materials used to manufacture them are anything but. To understand the materials used in the manufacture of thermistors, it's important to understand the basics of the device itself.
A thermistor is a type of temperature-sensing device composed of a semiconductor material that has been designed to change in electrical resistance as its temperature changes. The materials used to manufacture thermistors are chosen for their ability to change resistance in response to temperature. In general, thermistors are composed of two different types of materials: semiconductor materials and insulating materials.
The most common materials used in the manufacture of thermistors are semiconductor materials like silicon, germanium, and nickel. These materials are chosen for their ability to change their electrical resistance in response to changes in temperature. The electrical resistance of these semiconductor materials increases with increasing temperature, so they are often used in thermistors that measure higher temperatures.
Another type of semiconductor material used in thermistors is a metal oxide material, such as titanium dioxide. These materials exhibit a decrease in electrical resistance with increasing temperature, so they are more suitable for thermistors that measure lower temperatures.
Insulating materials such as glass, ceramic, and plastic are also used in the manufacture of thermistors. These materials are used to provide insulation between the semiconductor material and the environment, helping to protect the thermistor from damage. These materials also help to provide structural support and stability to the thermistor.
