What is a piezo transducer?

Piezoelectric transducer is a sensor made of piezoelectric effect produced by certain dielectrics. The so-called piezoelectric effect refers to the phenomenon that certain dielectrics undergo deformation, including bending and stretching deformation, due to the polarization of internal charges when they are deformed by external forces in a certain direction. The most common materials used in piezoelectric transducer are various types of piezoelectric ceramics belonging to piezoelectric polycrystals and quartz crystals.

How to check piezo element?

Piezoelectricity was first discovered in 1880 by Jacques and Pierre Curie. While experimenting with a variety of crystals, they discovered that applying mechanical pressure to specific piezo element like quartz released an electrical charge. It wasn’t until World War I when piezoelectric element was used for practical applications in sonar. Today, piezoelectric element is used everywhere that asking Google for directions to a new restaurant uses piezoelectric element in the microphone. However, if the piezo element does not make sound, how can we check whether piezo element is good or not?

How to solder piezo element?

Piezoelectric element refers to the use of piezoelectric technology in the transducer, indicator or as an independent device to produce audible devices. Piezoelectric element is a very sensitive device, its response time is only sub millisecond, which is much shorter than the blink time. When welding pins to piezoelectric elements, great care must be taken to prevent damage to the device.
