Growth of Automotive Industries, Low Manufacturing Cost, and its Wireless and Passive nature is driving the Acoustic Wave Sensor Market in APAC

APAC (China, Japan, and India) is the largest market for the acoustic wave sensor in terms of consumption. The main industries of APAC comprise automotive, process industries, healthcare, petrochemical, oil and gas, and consumer electronics. APAC’s market is currently riding a prosperous growth curve in terms of consumption of acoustic wave sensors for various applications. APAC, on the whole, generated revenue of $37.4 million from acoustic wave temperature sensor in 2014. On an average, there are around 7 wireless systems and up to 15 sensors used per vehicle for the measurement of temperature, pressure, and torque. Besides these, RF SAW sensors are used in vehicles as well. Consequently, growth of automotive industry will exponentially boost the market for acoustic wave sensors.

Automotive application recorded the second largest revenue in application market of acoustic wave sensor followed by industrial sector application in APAC region in 2014.

Another huge advantage of the acoustic wave sensor over the other sensors like capacitive or piezo-resistive is their wireless and passive nature. This infers that power is not separately applied to the sensor as it gets the energy from the interrogating RF pulse to excite the SAW and transmit its response. The wireless nature provides them the ability to measure parameters such as torque, pressure, and temperature on rotating components with simplicity. An added advantage is their small size and wireless nature, due to which acoustic wave sensors have a very low fabrication cost as compared to wired sensors, which amounts to approximately 15% to 20%.
