預計到 2026 年,聲波感測器市場規模將達到 19.6 億美元,高於 2025 年的 18 億美元。
預計到 2031 年將達到 30.1 億美元,2026 年至 2031 年的複合年成長率為 8.93%。

這一成長主要受以下因素驅動:5G 和 Wi-Fi 7 對高頻濾波器的強勁需求、交通運輸的電氣化、工業物聯網 (IIoT) 的快速普及以及小型化進程的持續推進。通訊基礎設施的升級推動了體聲波 (BAW) 濾波器的銷售,而表面聲波 (SAW) 裝置在 3 GHz 以下頻段的應用領域也保持著成長勢頭。電動車 (EV) 和高級駕駛輔助系統 (ADAS) 需要無電池無線感測技術,以減輕線束重量並抵抗強烈電磁干擾。 IIoT 使用者目前傾向於使用邊緣聲波感測器進行預測性維護,而可印刷壓電薄膜則實現了結構健康監測和醫療拋棄式產品領域的超低成本部署。在競爭格局方面,大型半導體公司的進入正在加速創新週期,而壓電基板供不應求和地緣政治風險在供應鏈中也日益凸顯。
隨著通訊業者升級到 5G 和 Wi-Fi 7,他們需要工作頻率高於 3 頻寬 的濾波器,而電子濾波器在該頻段的性能已接近極限。表面聲波 (SAW)頻寬,尤其是體聲波 (BAW) 裝置,能夠提供所需的陡峭滾降特性和低插入損耗。村田製作所 2024 年的產能擴張計畫與支援 6 GHz 頻段 Wi-Fi 7 的智慧型手機訂單直接相關。
電動車平台傾向於採用輕量化、無電池的感測器,這些感測器能夠採集振動或射頻能量。大陸集團將於2024年推出的無線聲學胎壓監測裝置,不僅符合ISO 26262功能安全標準,在高電磁干擾環境下也展現可靠性。
石英元件的溫度漂移為 20 至 50 ppm/°C,需要高成本的補償電路或氣密封裝,對於航太設計而言,-55°C 至 +125°C 的溫度範圍內,其成本可能比商用元件高成本%,而且振動應力會增加重新校準的需求。
預計到2025年,聲波感測器市場規模將達到11.9億美元。在製程工業中,由於可靠的電源供應和資料傳輸,有線方案仍然是首選。然而,價值6.1億美元的無線解決方案預計將成長更快,這主要得益於維修的經濟效益和電動車的需求。無線解決方案10.74%的複合年成長率反映了能源採集技術的進步,這些技術延長了維護週期。基於IEC 61508的標準化和冗餘射頻通訊協定正在推動其在關鍵任務系統中的應用。
風能產業的安裝商報告稱,森薩塔的無電池節點使用壽命延長了10年以上。無線部署被認為是聲波感測器市場的主要成長動力,因為佈線成本的降低和部署速度的加快可以抵消設備初始價格較高的問題。
預計到2025年,聲表面波(SAW)裝置的市場規模將達到12.4億美元(聲波感測器市場佔有率為69.10%),在3GHz以下頻段應用領域佔據主導地位,並得益於成熟且經濟的石英加工技術。然而,隨著通訊領域頻率的不斷提升,體聲波(BAW)裝置在3GHz以上頻段展現出卓越的性能優勢,從而帶來了5.6億美元的市場機會。 TDK在日本投資1億美元用於BAW元件,目標市場為Wi-Fi 7和5G設備,這將推動BAW元件實現兩位數的成長。
雖然 SAW 在工業和消費領域得到了廣泛應用,但基於物理原理的上限頻率限制確保了 BAW 在高頻寬需求領域繼續佔據主導地位。
預計到2025年,亞太地區將創造6.7億美元的市場規模,佔全球總營收的37.20%,複合年成長率(CAGR)為9.81%。中國不斷擴大的製造地和日本卓越的材料技術鞏固了該地區的市場主導地位。韓國5G的快速部署和電動車出口將進一步擴大該地區的聲波感測器市場規模。
北美緊追在後,投入5.1億美元,主要得益於工業IoT改裝和航太領域嚴格的可靠性要求。聯邦政府資助的高超音速飛行器監測計畫正在加速國防領域的應用。歐洲投入4.3億美元,受惠於電動車強制令以及強調永續性和工人安全的基建監測法規。
雖然中東、非洲和南美洲仍在發展中,但在石油和天然氣、採礦和智慧計劃中,無線、無電池節點非常適合偏遠和危險的地點,試點部署正在進行中。
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.
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.
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.
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.
