Mercury (the red liquid) is used in many older thermometers because it is the only metal which is liquid at room temperature and expands uniformly as the temperature increase. Thus, as the temperature rises and falls the mercury rises and falls inside of the thermometer and gives us a reading as to what temperature it is.
Most electronic thermometers used are called thermo-resistors. These types of thermometers use semiconductors that act as temperature sensitive resistors. The colder it is, the less conductive the semiconductor is. A computer measures the conductivity of the metal and determines the temperature based on the resistance of the semiconductor.
