Medical Thermometer - The Ever Evolving Device to Measure Body Temperature The first Medical Thermometer to measure body temperature was invented by Francesco Sagredo in 1592, though it was not very accurate. In 1886, Thomas Clifford Allbutt invented the clinical thermometer which was filled with mercury and became the standard tool for physicians to measure body temperature for over 100 years. Traditional glass mercury thermometers served their purpose well but had some drawbacks like being fragile and containing mercury which is a toxic metal. In late 1980s and early 1990s, digital thermometers were developed which eliminated these issues. Digital thermometers use thermistors - semiconductor devices whose resistance varies with temperature.
