Abstract
We are living in a sensor world. Sensors are used in the house, office, car, and other areas detecting our presence by turning lights on, adjusting room temperature, detecting fires, and many other tasks. Today sensor has become a “buzz word”, without which it is hard to imagine living. They play a vital role in all sectors including housing, industry, aviation, medicine, and automobiles to name a few. Sensors can be manufactured with many types of materials. However, sensors made of ceramics have significance and have advantages when compared to those made from other materials. This mini review examines ceramic sensors and their applications in various sectors including the materials used to build them and their functioning in different areas. The paper precisely reports ceramic sensors and their applications in industry, including the medical, automotive, and aviation sectors.
Highlights
Ceramics are solid materials that comprise inorganic compounds of metal or metalloids and nonmetals with covalent or ionic bonds
It is important to use and develop high-gastightness wireless pressure sensors that are fabricated with a silicon carbonitride (SiCN) ceramic material with large sensing distance (Yu et al, 2020)
Earlier work on high temperature insulation layers have reported the use of an Al2O3 thin film, which is deposited on metals, enhancing the capabilities of temperature insulation (Duan et al, 2017), but this thin film is removed when the temperature cycling test is finished, because of the thermal stress mismatch between the ceramic thin film and the metal (Sheng et al, 2013) giving rise to unrepeatable results not required for sensors
