The acoustic wave sensors market has been forecast to increase at a compound annual growth rate (CAGR) of 20.2% over the next five years, increasing from a valuation of $256.0 million in 2012, to hit a market value of $721.13 million by 2018.
In terms of volume, the unit shipment for acoustic wave sensors was 848.81 million units in 2012 and is expected to reach 2,985.40 million units by 2018, at an estimated CAGR of 24.8% from 2013 to 2018.
Acoustic wave sensors are so named because their detection mechanism is a mechanical, or acoustic, wave. As the acoustic wave propagates through or on the surface of the material, any changes to the characteristics of the propagation path affect the velocity and/or amplitude of the wave.
Changes in velocity can be monitored by measuring the frequency or phase characteristics of the sensor and can then be correlated to the corresponding physical quantity being measured.
Acoustic wave sensors are extremely versatile devices that are just beginning to realize their commercial potential. They are competitively priced, inherently rugged, very sensitive, and intrinsically reliable, and can be interrogated passively and wirelessly.
Wireless sensors are beneficial when monitoring parameters on moving objects, such as tire pressure on cars or torque on shafts. Sensors that require no operating power are highly desirable for remote monitoring of chemical vapours, moisture, and temperature.
Acoustic wave sensors are expected to show good growth across different application segments in the coming years due to their competitive advantages over other technologies.
As of now, temperature, pressure, torque, and viscosity sensors are the only ones to have reached complete commercialisation but a healthy growth has been predicted for other sensors as well in future, as more applications of acoustic wave sensors get realised in the years to come.
