Sensistor is a temperature dependent device whose resistance is dependent on temperature. It exhibits direct variation with respect to change in temperature & hence usually applicable for bias compensation.
Its functionality is exactly opposite to that of thermistor which exhibits negative temperature coefficient of resistivity.
As the resistance of sensistor increases due to increase in temperature, it is also said to have the property of positive temperature coefficient of resistivity.
