Friedrich Reinitzer, an Austrian chemist, discovered liquid crystals in 1888. However, it was George Friedel, a French mineralogist, who later developed the first liquid crystal thermometer in 1889.

A thermometer is not adequate in this situation.


Is there any thermometer which changes its colour due to temperature change?

Yes,its called as "liquid crystal thermometer".


How do you use Liquid Crystal Thermometer for measuring temperature?

Liquid crystal thermometers utilize liquid crystals that change color based on temperature. Simply place the thermometer strip on the object you wish to measure the temperature of, and the liquid crystals will change color to indicate the temperature. Consult the packaging for a color guide to interpret the temperature reading accurately.

The liquid crystal display (LCD) was invented by George H. Heilmeier, a physicist working for RCA, in 1968. His work laid the foundation for the development of LCD technology that we use in many electronic devices today.


Who invented the water thermometre?

The water thermometer, or the thermoscope, was invented by Galileo Galilei. It was based on the idea that the density of a liquid changes with the temperature.


Different kinds of thermometer and their uses?

Different types of thermometer and their uses 1. liquid-in-glass thermometer: weather recording and laboratory uses. (Temperature sensor: laboratory uses.<--this may not count as one of the thermometers XD ) 2. infra-red thermometer: measuring body temperature. 3. rotary thermometer: measuring the temperature of ovens and freezers. 4. resistance thermometer: measuring temperatures from -200 degree C to 1000 degree C, e.g. engines and ovens, etc. 5. thermistor thermometer: measuring the temperature of human body and electrical appliances. 6. liquid crystal thermometer: measuring the temperature of human body and fish tanks. ( the color of liquid crystal changes with temperature.)

Who invented liquid crystal diode?

The term "liquid crystal diode" was invented by patent lawyers in late 1970's for the emerging liquid crystal display technology to rhyme with the then dominant light emitting diode display technology. The term is misleading as the liquid crystal cell is not a diode in the ordinary meaning of the word. Since then the incorrect term has been adopted to patents (over 600 patents describing liquid crystal cells as diodes) and scientific literature in addition to its misuse in lay-articles in internet.
