Market Trends of US Acoustic Sensors Industry
This section covers the major market trends shaping the US Acoustic Sensors Market according to our research experts:
Pressure Sensors to Drive the Market Growth
- The pressure sensor is an instrument consisting of a pressure-sensitive element to determine the actual pressure applied to the sensor (using different working principles) and some components to convert this information into an output signal. These sensors have witnessed significant growth due to the increasing applications across various industries, such as oil and gas, aerospace, automotive, healthcare, consumer goods, industrial, etc.
- The growing adoption of surface acoustic wave pressure sensors for permanent sound monitoring systems in the oil and gas industry has replaced the quartz crystals, and fiber optics which dominated the market for downhole pressure gauges, is expected to drive the market in the forecast period.
- These pressure sensors can be used in a car tire pressure monitoring system. This kind of sensor takes advantage of the fact that a SAW can be used wirelessly and without a battery. With a one-port SAW resonator and antenna, the Tire Pressure Monitoring System (TMPS) can be stimulated by signals of different frequencies and then received back from the SAW.
- In the past few years, exclusive cross-country and off-road cars have been witnessed installing innovative tire pressure control systems. For instance, the G63 AMG 6X6 from the Mercedes enables the driver to check and vary the tire pressure of both the front and rear axles separately. Reportedly, the system takes less than 20 seconds to raise the tire pressure from 0.5 bar to 1.8 bar.
- Furthermore, the NHTSA has mandated the use of TPMS (tire pressure monitoring system) since 2002. Hence, the US automotive sector has been leading the market studied, owing to a robust automotive sector.

Consumer Electronics holds the highest market share
- There is a significant surge in acoustic sensors and other related equipment sales due to the increasing smartphone sales and the increasing adoption of emerging RF technologies in consumer electronics, expanding the scope of the market studied.
- The growing production of LTE, 4G & 5G devices, especially 5G smartphones, also creates a massive growth opportunity for the SAW technology provider. RF filters are becoming standard components in these devices as they isolate radio signals from the different spectrum bands used by various smartphones to receive and transmit information. New advanced SAW filters offer a higher performance solution than competing for BAW filters in the sub-2.7 GHz frequency range, hence having higher growth opportunities with the emergence of 5G technology.
- For instance, in February 2020, US-based Qualcomm Technologies Inc. announced the Qualcomm ultraSAW filter technology, another groundbreaking innovation in its wireless technology portfolio mainly targeting 5G/4G Mobile Devices. According to the company, RF filters isolate radio signals from the different spectrum bands, and by achieving as much as 1 dB improvement in insertion loss, Qualcomm ultraSAW filters offer a higher performance solution than competing filters in the sub-2.7 GHz frequency range.
- Many researchers are also exploring the scope of the SAW MEMS microphone that can also be used as a wireless passive accelerometer and pressure sensor. The global MEMS microphone market will be expected to cross USD 1.67 billion by 2024.
