thumb|Example of electronic circuit with the sensistor '''Rs'''
'''Sensistor''' is a resistor whose resistance changes with temperature.
The resistance increases exponentially with temperature,<ref>U.A.Bakshi, A.P.Godse, ''Semiconductor Devices & Circuits'', Technical Publications Pune, India, 2008, {{ISBN|978-81-8431-298-0}}, page 295</ref> that is the temperature coefficient is positive (e.g. 0.7% per degree Celsius).<ref>Proceedings of the Institute of Radio Engineers, Volume 48, Issues 10-12, page 1889</ref>
Sensistors are used in electronic circuits for compensation of temperature influence or as sensors of temperature for other circuits.<ref>{{Cite web |url=http://focus.ti.com/lit/ds/slus281/slus281.pdf |title=UC3704, Bridge Transducer Switch, Texas Instruments (accessed on 2010-01-14) |access-date=2010-01-14 |archive-date=2011-06-04 |archive-url=https://web.archive.org/web/20110604172908/http://focus.ti.com/lit/ds/slus281/slus281.pdf |url-status=dead }}</ref>
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 metal<ref>Dharma Raj Cheruku, Battula Tirumala Krishna, Electronic Devices and Circuits, 2nd edition, 2008, Delhi, India, {{ISBN|978-81-317-0098-3}}</ref> and the resistance change is more gradual than it is the case for other PTC thermistors.
