Sensor-generators, beepers, piezoelectric ceramic chips, and ultrasonic sensors are electronic components based on the principle of the piezoelectric effect and are widely used in various types of sensors and energy harvesting systems. Sensor generators generate voltage signals through external forces and can be used in low-power sensors and self-powered devices. Buzzer wafers, on the other hand, can produce sound through electrical signal-driven vibration and are commonly used in alarms, beeps, and other scenarios. Piezoelectric ceramic sheets utilize the piezoelectric effect of ceramic materials to convert mechanical energy into electrical energy or reverse operation and are commonly used in vibration monitoring, medical ultrasound, and other fields. Ultrasonic sensing chip is mainly used in ultrasonic sensors, through the emission and reception of ultrasonic signals to achieve object detection, distance measurement, and other functions. Single-sided power generating sheet refers to the sheet structure with piezoelectric material on one side only, which is suitable for energy harvesting and sensing applications.

Piezoelectric ceramic power generator Piezoelectric ceramic power generation efficiency is generally about 10%. The main factors affecting the power generation efficiency of piezoelectric ceramics include the physical properties of the material itself, the vibration frequency, and the external circuit. By means of connecting multiple components in series and optimizing the vibration method, the power generation efficiency of piezoelectric ceramics can be improved, thus realizing sustainable power generation.
Piezoelectric ceramics, as a special electronic material, has the ability to convert mechanical energy into electrical energy or electrical energy into mechanical energy. This unique property makes piezoelectric ceramics have a wide range of applications in the fields of sensors, actuators, and energy harvesters. As an important indicator of the performance of piezoelectric ceramics, the electrical energy conversion efficiency has a decisive influence on its performance in practical applications.
