Acoustic wave devices

Acoustic wave devices use sound waves that travel along or inside a material to perform functions like filtering signals or sensing physical changes. These devices generate high-frequency sound waves—called acoustic waves—using tiny components, and as these waves move through the device, they can be affected by touch, pressure, temperature, or chemical changes. This allows the device to detect or process information, making them crucial in smartphones, sensors, and communication systems. Essentially, they harness the properties of sound at very high frequencies to enable precise and fast signal manipulation or measurement.
