Sensistor is a resistor whose resistance changes with temperature.
The resistance increases exponentially with temperature,U.A.Bakshi, A.P.Godse, Semiconductor Devices & Circuits, Technical Publications Pune, India, 2008, , page 295 that is the temperature coefficient is positive (e.g. 0.7% per degree Celsius).Proceedings of the Institute of Radio Engineers, Volume 48, Issues 10-12, page 1889
Sensistors are used in electronic circuits for compensation of temperature influence or as sensors of temperature for other circuits.
Sensistors are made by using very heavily doped semiconductors so that their operation is similar to PTC-type thermistors. However, very heavily doped semiconductor behaves more like a metalDharma Raj Cheruku, Battula Tirumala Krishna, Electronic Devices and Circuits, 2nd edition, 2008, Delhi, India, and the resistance change is more gradual than it is the case for other PTC thermistors.
