Material, type and size:
Thermistors are bulk semiconductor devices and as such can be manufactured in a variety of forms. More common ones include discs, beads and rods. Sizes do vary from 1mm beads to discs a few centimeters in diameter and thickness.
There are different types of thermistors, most of which respond differently to changes in temperature. Thermistors are not linear and their response curves vary from type to type. Some thermistors have a nearly linear temperature-resistance relationship, others have a sharp change in slope (sensitivity) at a specific characteristic temperature.

Working principle of temperature sensor
Using the NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
