An electrical temperature sensor (10) comprises a liquid crystalline material (12). First and second electrically conductive contacts (14), (16), having a spaced relationship therebetween, contact the liquid crystalline material (12). An electric property measuring device is electrically connected to the first and second contacts (14), (16) and is arranged to measure an electric property of the liquid crystalline material (12). The liquid crystalline material (12) has a transition temperature T at which it undergoes a phase change between polar and non-polar phases. The phase change between polar and non-polar phases causes a change in said electric property of the liquid crystalline material (12).
An electrical temperature sensor comprising:
An electrical temperature sensor comprising a plurality of temperature sensor cells, each cell according to a temperature sensor of any of the preceding claims, wherein the transition temperature T of the liquid crystalline material in at least two of the temperature sensor cells is different.
A method of temperature sensing using a liquid crystalline material having a transition temperature T at which it undergoes a phase change between polar and non-polar states, the phase change between polar and non-polar states causing a change of an electric property of the liquid crystalline material;
