The working principle of piezoelectric ceramic chips is based on the piezoelectric effect. When external pressure is applied, the chip undergoes deformation, which leads to a redistribution of internal charges and generates voltage. This voltage can be measured and utilized, for example, in medical ultrasound imaging, piezoelectric ceramic chips are used to generate high-frequency sound waves. After encountering human tissue, the sound waves reflect back and are received by the chips. By measuring the reflected sound waves, structural information inside the human body can be obtained. In sound sensors, piezoelectric ceramic chips are used to convert sound into electrical signals, thereby achieving sound detection and amplification.

In addition to its applications in the fields of medicine and sound sensors, piezoelectric ceramic chips also play important roles in many other fields. For example, in automotive safety systems, piezoelectric ceramic chips are used to detect collision events and trigger the deployment of airbags. In environmental monitoring, piezoelectric ceramic chips are used to measure parameters such as pressure, temperature, and gas concentration. In the aerospace field, piezoelectric ceramic chips are used to manufacture high-precision inertial sensors such as accelerometers and gyroscopes.
