Piezoelectric Plate 28mm

The 28mm Piezoelectric Plate is a compact, lightweight, and highly efficient electronic component designed to convert electrical energy into mechanical vibrations and mechanical pressure into electrical signals using the piezoelectric effect. With a standard diameter of 28mm, this versatile component is widely used in sound generation, vibration sensing, impact detection, and frequency-based electronic applications. Its reliable performance, low power consumption, and fast response make it an essential component for a wide range of electronic, industrial, educational, and DIY projects.

The piezoelectric plate consists of a thin ceramic piezoelectric element bonded to a durable metal disc. When an alternating electrical voltage is applied, the ceramic material rapidly expands and contracts, causing the metal disc to vibrate and produce audible sound. Conversely, when the plate experiences mechanical pressure, vibration, or impact, it generates a small electrical voltage that can be detected by electronic circuits. This dual functionality allows the same component to be used as both a sound-producing device and a vibration or touch sensor.

The 28mm piezoelectric plate offers excellent sensitivity, stable frequency response, and reliable operation over extended periods. Its low power requirements make it ideal for battery-operated devices, portable electronics, and energy-efficient systems. The lightweight and thin construction allows easy integration into compact electronic products without adding significant weight or occupying much space.

The component is commonly used in electronic buzzers, alarm systems, doorbells, timers, musical instruments, vibration sensors, knock detection circuits, touch-sensitive switches, security systems, ultrasonic experiments, and educational electronics projects. It is also suitable for Arduino, ESP32, Raspberry Pi, robotics, IoT devices, embedded systems, and microcontroller-based projects where sound generation or vibration sensing is required.

The exposed metal surface provides convenient electrical connections, making the plate easy to solder and integrate into printed circuit boards (PCBs), prototype boards, or custom electronic assemblies. Its durable construction ensures long operational life with consistent performance under normal operating conditions.

The 28mm Piezoelectric Plate is widely used in schools, engineering laboratories, electronics workshops, research projects, prototype development, and repair applications. It is an excellent choice for students, hobbyists, technicians, and professional engineers who require a dependable component for audio output, sensing, and experimental applications.

Whether used to generate alert sounds, detect mechanical movement, build interactive electronic projects, or develop innovative sensor-based systems, the 28mm Piezoelectric Plate delivers reliable performance, fast response, and excellent versatility, making it an indispensable component in modern electronics.
