ABSTRACT
Temperature is a fundamental physical property in both scientic and industrial elds. It is one of the primary physical quantities that is routinely measured to derive other thermodynamic quantities such as heat, energy, or specic heat capacity (the ratio of the amount of heat, measured in calories, required to raise the temperature of 1 g of a substance by 1°C to the amount of heat required to raise the temperature of a similar mass of a reference material, usually water, by the same amount); thermodynamics is the science that deals with the relationships and conversions between heat and other forms of energy, most notably mechanical work. Temperature sensing is therefore a vital requirement in many parts of industry including aerospace (comprises the atmosphere of the Earth and surrounding space, typically referring to industry concerned with vehicles moving through air and space), nuclear, mechanical, chemical, and medical technologies. If these sensors are small in size, they can be readily embedded in the systems without intrusion.
