Product Definition and Technology Overview
Surface Acoustic Wave Sensors operate by generating and detecting acoustic waves that propagate along the surface of a piezoelectric substrate, typically quartz or lithium niobate. Variations in physical parameters—such as pressure, temperature, torque, or chemical composition—affect the wave properties, which are then converted into measurable electrical signals.
SAW sensors are passive and wireless, powered entirely by external radio-frequency (RF) signals, making them uniquely suitable for monitoring components in motion or in inaccessible locations. This design eliminates the need for onboard power sources, reduces maintenance, and minimizes wiring complexity. Applications range from tire pressure and torque monitoring in automotive systems to vibration and environmental sensing in industrial machinery.
These sensors are also highly resilient in harsh operating conditions, including high temperatures, mechanical vibrations, and chemically aggressive environments, outperforming traditional wired or active sensors. Their small size, high sensitivity, and long operational lifespan make them ideal for adoption in emerging technologies such as autonomous vehicles, electric vehicles (EVs), and industrial IoT ecosystems.
