Semiconductor ceramic arm:

Ceramic arm Semiconductor ceramics refer to electronic ceramics that have semiconductor crystal grains and semiconducting grain boundaries through semiconductorization measures, thereby showing strong interface barriers and other semiconductor characteristics. Its electrical conductivity changes significantly due to changes in external conditions (temperature, light, electric field, atmosphere, temperature, etc.), so it can convert physical changes in the external environment into electrical signals to make sensitive components for various purposes. The ceramic arm is made of alumina ceramic material by Huamin Ceramics. The semiconductor ceramic arm can provide a good arm clamping solution for industrial robots. It has the excellent characteristics of light weight, wear resistance and corrosion resistance.

Ceramic Encyclopedia:

At present, semiconductor ceramics can be divided into photosensitive ceramics, heat-sensitive ceramics, pressure-sensitive ceramics, humidity-sensitive ceramics, and gas-sensitive ceramics. In real life, the core component of the alcohol tester that we often see is the gas sensor; the fire alarm installed on the ceiling of the building not only contains the gas sensor, but also contains other components such as thermal sensors. Once there is a lot of smoke in the building, the fire alarm can detect it immediately.
