Application case of conductive coating in ceramic electronic devices

1. Ceramic capacitors

Ceramic capacitors are a common type of ceramic electronic device used for storing and releasing charges. In traditional ceramic capacitors, due to the non-conductive nature of ceramic materials, metal electrodes need to be added to achieve current conduction. However, usingConductive coating adhesiveIt can simplify the manufacturing process, reduce materials and costs, while achieving the conductivity of ceramic capacitors.

2. Ceramic piezoelectric sensor

Ceramic piezoelectric sensors are devices that can convert mechanical energy into electrical energy and vice versa. Traditional ceramic piezoelectric sensors typically use metal electrodes connected to ceramic materials to achieve charge conduction. However, metal electrodes may cause thermal expansion mismatch between electrodes and ceramic materials, leading to a decrease in device performance. The use of conductive coating can avoid this problem and improve the stability and reliability of the device.

3. Ceramic pressure sensor

Ceramic pressure sensor is a device that can measure the pressure of an object and convert it into an electrical signal. In traditional ceramic pressure sensors, metal wires or wires need to be connected to the ceramic material to achieve current conduction. However, the connection between metal and ceramic may be affected by external environmental factors such as temperature and humidity, leading to unstable sensor operation. By using conductive coating, the thermal expansion mismatch between metal and ceramic can be reduced, improving the performance and reliability of the sensor.
