Sensitive components are important components of sensors that are sensitive to certain physical, chemical, and biological information and turn it into special electronic components of electrical information.
A special electronic component that is sensitive to physical, chemical, and biological information and transforms it into electrical information. This component is usually made from some sensitive effect of the material. Sensitive components can be named according to the physical amount of input, such as thermal (see thermistor), photosensitivity, (electric) pressure (pressure) force sensitivity, magnetic sensitivity, gas sensitivity, wet sensitive elements. The use of sensitive components in electronic devices to perceive external information can achieve or exceed the function of human sensory organs. Sensitive components are the core components of the sensor. With the rapid development of electronic computers and information technology, sensitive components are becoming more and more important.
