An electrical resistor whose resistivity is sensitive to temperature. This allows for accurate measurement of temperature by measuring the resistance across the thermistor. Thermistors are more accurate at lower temperatures, -50 C to 250 C. Thermocouples are more common at higher temperatures.
In additive manufacturing, thermistors are used for lower temperature applications where they are still accurate but cost less than thermocouples. Most hobby and maker fused deposition modeling systems use a thermistor to measure and control the nozzle temperature.
