Acoustic Sensors - Market Share Analysis, Industry Trends & Statistics, Growth Forecasts (2026 - 2031)
Market Report I 2026-02-09 I 161 Pages I Mordor Intelligence
Acoustic Sensors Market Analysis
Acoustic sensor market size in 2026 is estimated at USD 1.96 billion, growing from 2025 value of USD 1.8 billion with 2031 projections showing USD 3.01 billion, growing at 8.93% CAGR over 2026-2031. The expansion is fueled by soaring high-frequency filtering demand for 5G and Wi-Fi 7, electrification in transportation, rapid industrial Internet of Things (IIoT) adoption, and continuing miniaturization initiatives. Telecommunications infrastructure upgrades are propelling bulk acoustic wave (BAW) filter sales, while surface acoustic wave (SAW) devices sustain growth in sub-3 GHz applications. Electric vehicles (EVs) and advanced driver assistance systems (ADAS) require battery-free wireless sensing to cut harness weight and withstand strong electromagnetic interference. IIoT users now favor edge-enabled acoustic sensors for predictive maintenance, and printed piezoelectric films promise ultra-low-cost deployments across structural health and medical disposables. Competitive dynamics reflect semiconductor majors entering the space, intensifying innovation cycles but exposing the supply chain to piezoelectric substrate shortages and geopolitical risks.
Global Acoustic Sensors Market Trends and Insights
Rapid 5G and Wi-Fi 7 Infrastructure Driving High-Frequency Filter Demand
Telecommunications providers upgrading to 5G and Wi-Fi 7 need filters operating above 3 GHz, a range where electronic alternatives falter. SAW and especially BAW devices deliver the required steep roll-off and low insertion loss. Murata's 2024 capacity expansion directly aligns with smartphone orders targeting the 6 GHz Wi-Fi 7 band.
Automotive Electrification Accelerating Wireless Sensing Adoption
EV platforms favor lightweight, battery-free sensors that harvest vibration or RF energy. Continental's 2024 launch of wireless acoustic tire-pressure units illustrates reliability under high electromagnetic interference while meeting ISO 26262 functional-safety demands.
Temperature Drift and Harsh-Environment Packaging Limitations
Quartz-based devices drift 20-50 ppm / C, forcing costly compensation or hermetic sealing. Aerospace designs spanning -55 C to +125 C may cost 300-500% more than commercial units, and vibration stresses accelerate recalibration needs.
Other drivers and restraints analyzed in the detailed report include:

Segment Analysis
The acoustic sensor market size attributed to wired devices reached USD 1.19 billion in 2025. Wired formats remain favored for reliable power and data in process industries. However, wireless solutions, valued at USD 0.61 billion, are growing faster due to retrofit economics and EV demand. Wireless solutions' 10.74% CAGR reflects energy-harvesting breakthroughs that extend maintenance intervals. Standardization under IEC 61508 and redundant RF protocols improves acceptance in mission-critical systems.
Installers in wind energy report service-life gains exceeding 10 years from Sensata's battery-free nodes. Lower cabling costs and accelerated deployment offset initial device premiums, positioning wireless deployments as a primary growth vector in the acoustic sensor market.
SAW devices contributed USD 1.24 billion, equal to 69.10% acoustic sensor market share in 2025, favored for sub-3 GHz applications and mature, economical quartz processing. Yet ascending frequencies in telecom open USD 0.56 billion BAW opportunities with performance advantages above 3 GHz. TDK's USD 100 million Japanese line targets Wi-Fi 7 and 5G handsets, validating BAW's double-digit expansion.
While SAW maintains broad adoption across industrial and consumer segments, physics-based frequency ceilings ensure BAW's sustained outperformance wherever high-band requirements dominate.
The Acoustic Sensor Market Report is Segmented by Type (Wired, Wireless), Wave Type (Surface Acoustic Wave, Bulk Acoustic Wave), Sensing Parameter (Temperature, Pressure, Torque, Humidity, Mass, Viscosity), Application (Automotive, Aerospace and Defense, Consumer Electronics, Healthcare, Industrial, Environmental Monitoring, Other Applications), and Geography. The Market Forecasts are Provided in Terms of Value (USD).
Geography Analysis
Asia-Pacific provided USD 0.67 billion, commanding 37.20% 2025 revenue and pacing at 9.81% CAGR. China's fab expansions and Japan's materials leadership buttress regional advantages. South Korea's rapid 5G roll-out and EV exports further enlarge the regional acoustic sensor market size.
North America followed with USD 0.51 billion, sustained by IIoT retrofits and stringent aerospace reliability requirements. Federal programs funding hypersonic vehicle monitoring accelerate defense uptake. Europe delivered USD 0.43 billion, benefiting from EV mandates and infrastructure monitoring regulations emphasizing sustainability and worker safety.
Middle East and Africa and South America remain nascent yet attract pilot deployments for oil-and-gas, mining, and smart-city projects where wireless battery-free nodes suit remote or hazardous locales.
