Acoustic Sensors Market Analysis by Mordor Intelligence
The acoustic sensor market size stands at USD 1.8 billion in 2025 and is projected to reach USD 2.77 billion by 2030, advancing at a 9.01% CAGR. 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.
