For chief technology officers at medical imaging device manufacturers, product managers at point-of-care ultrasound companies, and investors in wearable health technology, a persistent engineering challenge remains: traditional piezoelectric ceramic-based ultrasound transducers (PZT) are bulky, power-hungry, expensive to manufacture, and difficult to integrate with CMOS electronics. These limitations hinder the development of portable, low-cost, and wearable ultrasound devices. Micromachined ultrasound transducers (MUTs) directly resolve this challenge through MEMS (microelectromechanical systems) technology, creating micrometer-scale structures that achieve electroacoustic signal conversion with smaller size, lower power consumption, easier CMOS integration, and mass production scalability. According to the latest industry benchmark, the global market for Micromachined Ultrasound Transducer was valued at USD 226 million in 2024 and is forecast to reach a readjusted size of USD 319 million by 2031, growing at a compound annual growth rate (CAGR) of 5.1% during the forecast period 2025-2031. This steady growth reflects increasing adoption of MUTs in medical imaging (particularly handheld and point-of-care ultrasound), emerging wearable ultrasound patches, and industrial non-destructive testing applications.

1. Product Definition: MEMS-Based Electroacoustic Transducers for Ultrasound
A micromachined ultrasound transducer (MUT) is an ultrasound transducer manufactured using microelectromechanical systems (MEMS) technology. It achieves electroacoustic signal conversion through micrometer-scale intricate structures (typically membrane-based) and is a core component of next-generation medical ultrasound systems, wearable patches, and industrial sensors. Compared to traditional transducers using rigid piezoelectric ceramics (PZT), MUTs offer four key advantages: (1) smaller size – enabling handheld and catheter-based devices; (2) lower power consumption – extending battery life for portable systems; (3) easier integration with CMOS electronic devices – enabling “ultrasound-on-a-chip” architectures; (4) mass production using semiconductor manufacturing processes – reducing per-unit cost.
Two primary technology categories (segment by type – QYResearch classification):
- Piezoelectric Micromachined Ultrasound Transducer (PMUT) – Uses a thin piezoelectric film (e.g., aluminum nitride AlN, lead zirconate titanate PZT, or potassium sodium niobate KNN) deposited on a silicon membrane. When voltage is applied, the film deforms, causing the membrane to vibrate and generate ultrasound. PMUTs offer high output pressure, good receive sensitivity, and simpler drive electronics (no high DC bias voltage). They are well-suited for therapeutic ultrasound and high-frequency imaging (>20 MHz). Key players: Philips (PMUT technology), Hitachi.
- Capacitive Micromachined Ultrasound Transducer (CMUT) – Uses a capacitive cell structure: a suspended conductive membrane over a fixed electrode, separated by a vacuum gap. A DC bias voltage collapses the membrane toward the fixed electrode; an AC signal then causes membrane vibration. CMUTs offer ultra-wide bandwidth (100-150%, vs. 50-70% for PMUTs and PZT), excellent receive sensitivity, and compatibility with standard CMOS processes. They require higher DC bias voltages (20-200V) and more complex drive electronics. CMUTs are expected to capture more significant market share in the future due to their ultra-high bandwidth, which enables high-resolution imaging and harmonic imaging modes. Key players: Butterfly Network (CMUT-based whole-body ultrasound-on-chip), Kolo Medical, Exo Imaging (CMUT-based handheld devices).
End-user segments (segment by application):
- Medical Imaging – Largest segment (~90-95% of revenue). Includes handheld ultrasound devices, point-of-care systems, intracardiac echocardiography (ICE) catheters, intravascular ultrasound (IVUS), and endoscopic ultrasound (EUS).
- Other – Industrial non-destructive testing (NDT), environmental water monitoring, wearable patches for remote patient monitoring, and emerging applications.
2. Industry Development Trends: Wearable MUTs, CMOS Integration, and Emerging Applications
Based on analysis of corporate annual reports (Butterfly Network, Philips, Exo Imaging), industry news from Q4 2025 to Q2 2026, and medical device trends, four dominant trends shape the micromachined ultrasound transducer sector:
2.1 Wearable Ultrasound Patches and Continuous Monitoring
Especially with breakthroughs in flexible MUT technology, micromachined ultrasound transducers (MUTs) are expected to give rise to wearable ultrasound imaging devices and smart skin patches for long-term continuous monitoring, providing strong support for telemedicine and personalized health management. Unlike conventional rigid probes, flexible MUTs can conform to skin curvature (abdomen, chest, neck, arm), enabling continuous monitoring of deep tissue parameters: (1) cardiac function – continuous left ventricular volume assessment, ejection fraction trending; (2) blood pressure and central aortic pressure waveform – via artery cross-sectional area measurement; (3) bladder volume – for spinal cord injury or elderly patients with voiding dysfunction; (4) muscle activity – for rehabilitation monitoring. Over the past six months, several academic groups (UC San Diego, Caltech) and startups have demonstrated wearable CMUT patches with wireless power and data transmission. However, commercialization faces challenges: battery life, data processing (real-time image reconstruction on low-power processors), and regulatory approval for continuous monitoring devices.
2.2 CMOS Integration Driving “Ultrasound-on-a-Chip”
CMUTs’ compatibility with standard CMOS processes (they can be fabricated on the same wafer as drive electronics) enables “ultrasound-on-a-chip”: a single integrated circuit containing thousands of transducer elements, beamforming electronics, and analog-to-digital converters. Butterfly Network (Butterfly iQ, iQ+) pioneered this approach, creating a handheld, whole-body ultrasound probe (curvilinear, linear, phased array on one chip) that connects to a smartphone, priced at USD 2,000-4,000 (vs. USD 10,000-50,000 for traditional cart-based systems). Butterfly has shipped over 100,000 probes globally, with applications in emergency medicine, primary care, obstetrics, and low-resource settings. Exo Imaging (Exo Iris) uses CMUT technology for a comparable handheld device, emphasizing image quality and artificial intelligence (AI) assistance.
2.3 High-Frequency and High-Resolution Imaging
MEMS fabrication enables transducers with much higher center frequencies (20-100 MHz) than PZT-based devices (2-15 MHz). High-frequency MUTs are enabling: (1) intravascular ultrasound (IVUS) – 40-60 MHz probes for coronary artery plaque characterization; (2) intracardiac echocardiography (ICE) – 10-20 MHz catheters for electrophysiology procedures; (3) ophthalmic ultrasound – 20-50 MHz for detailed anterior segment imaging; (4) dermatology – 50-100 MHz for skin cancer margin assessment. As MUT fabrication yields improve and costs decline, these high-frequency applications will grow faster than the overall market.
2.4 Emerging Applications in Industrial and Environmental Monitoring
Beyond medical imaging, MUTs are expanding into industrial non-destructive testing (NDT) and environmental water monitoring. In NDT, MUT arrays can be conformably attached to pipes, tanks, and structures for corrosion monitoring and crack detection. In water monitoring, MUT-based sensors detect suspended particles, bubbles, and flow rates. While currently a small segment (<5% of MUT market), these non-medical applications are growing at 8-10% CAGR and diversify revenue away from healthcare cyclicality.
Industry Layering Perspective: CMUT vs. PMUT Comparison
- CMUT – Advantages: ultra-wide bandwidth (100-150%), excellent receive sensitivity, CMOS compatible, scalable to large 2D arrays. Disadvantages: requires high DC bias (20-200V), complex drive electronics, potential for stiction (membrane sticking to substrate). Best suited for high-resolution diagnostic imaging (whole-body, cardiology, obstetrics, vascular). Market share (revenue) ~55-60%, faster growing (6-7% CAGR).
- PMUT – Advantages: simpler drive electronics (no high DC bias), higher output pressure for therapy, lower operating voltage. Disadvantages: narrower bandwidth (50-70%), lower receive sensitivity, less CMOS compatible. Best suited for therapeutic ultrasound (focused ultrasound, drug delivery), high-frequency applications, and where CMOS integration is less critical. Market share ~40-45%, steady growth (4-5% CAGR).

4. Exclusive Expert Insights and Recent Developments (Q4 2025 – Q2 2026)
Insight #1 – Butterfly Network’s Path to Profitability
Butterfly Network, after a SPAC merger in 2021 and subsequent stock decline, has focused on cost reduction and subscription revenue (hardware low-margin, software/cloud recurring revenue). In 2025, Butterfly’s annual report showed revenue of USD 80-90 million (estimated), with positive adjusted EBITDA for the first time. The company’s strategy: sell hardware at near-cost (USD 2,000-3,000 for Butterfly iQ+, USD 4,000-5,000 for higher-tier), generate recurring revenue from cloud storage, AI analysis (Auto B-line counter, EF quantification), and enterprise subscriptions. For investors, this model (razor-blade in software) is promising but requires scale. Over the past six months, Butterfly announced partnerships with several US hospital systems and deployed devices in low-resource settings (Africa, India) via philanthropy and NGO funding.
Insight #2 – Flexible CMUT for Wearable Monitoring
Researchers at UC San Diego (January 2026) published a wearable CMUT patch (2 cm × 2 cm, 1 mm thick, 10 MHz center frequency) that adheres to the chest and continuously monitors cardiac function (left ventricular ejection fraction, LVEF). The patch connects to a smartphone via Bluetooth, runs on battery for 4 hours, and uses AI to auto-segment cardiac chambers. While not yet commercialized, the demonstration indicates that wearable MUTs for continuous home monitoring of heart failure patients could be commercially available within 2-3 years. This would represent a significant expansion of the MUT market beyond episodic imaging.
Insight #3 – China’s Domestic MUT Development
China’s medical ultrasound market is dominated by Mindray, Siemens Healthineers, GE Healthcare, Philips. However, domestic MUT startups (not listed in QYResearch top players) are developing lower-cost alternatives to Butterfly’s CMUT. Several have received NMPA approval for handheld devices priced at USD 800-1,500 (30-50% below Butterfly). International MUT manufacturers are responding by establishing China-based manufacturing to reduce costs and qualify for domestic procurement preferences.
Typical User Case (Q1 2026 – Rural Health Clinic, India):
A rural primary health clinic in India, without on-site radiologist or ultrasound technician, purchased a Butterfly iQ+ handheld ultrasound probe (CMUT-based). A nurse with 2 hours of training performed obstetric scans on 50 pregnant women over 3 months. The probe’s AI guidance (Auto B-line, fetal biometry) provided diagnostic-quality images; images were uploaded to cloud and interpreted by a remote radiologist (200 km away) within 4 hours. Previously, patients had to travel 200 km for any ultrasound (cost USD 50 + travel). The clinic’s per-scan cost: USD 5 (device amortization + cloud fee). The state health department is considering scaling the program to 500 clinics.
5. Technical Challenges and Future Pathways
Despite growth, technical challenges persist for micromachined ultrasound transducer adoption:
- Acoustic material performance – The upstream industrial chain includes the research and supply of acoustic functional materials such as special piezoelectric ceramics (for PMUTs), silicon-based materials, and flexible polymer materials (for flexible MUTs). The performance of these materials directly determines final transducer sensitivity, bandwidth, and output pressure. PMUTs using AlN have lower piezoelectric coefficients (d33, d31) than bulk PZT, limiting transmit output power. Research into higher-performance thin-film piezoelectrics (scandium-doped AlN, PZT, KNN) continues.
- Flexible MUT manufacturing yield – The midstream segment involves the design, manufacturing, and packaging of MUT devices. The reliable manufacturing process of flexible MUTs is a key challenge that needs to be overcome. Flexible MUTs require MEMS fabrication on polymer substrates (polyimide) or transfer printing of pre-fabricated devices onto flexible carriers. Both approaches have lower yields (<70% vs. >90% for rigid silicon MUTs) and higher costs. Until yields improve, flexible MUTs will remain expensive and limited to high-value applications.
- CMOS integration complexity – While CMUTs are CMOS compatible, monolithic integration (fabricating CMUT and electronics on same wafer) requires process modifications to protect electronics during MEMS release etch (e.g., HF vapor release). Hybrid integration (bonding CMUT wafer to electronics wafer) is easier but increases parasitic capacitance and reduces signal-to-noise ratio. Butterfly uses a custom CMOS process co-designed with its foundry partner; replication by competitors requires significant engineering investment.
Future Direction: The micromachined ultrasound transducer market will continue its 5%+ CAGR through 2031, driven by: (1) handheld and point-of-care ultrasound adoption (cost, portability, AI guidance), (2) wearable MUTs for continuous monitoring (chronic disease management, post-discharge monitoring), (3) high-frequency applications (IVUS, ICE, dermatology, ophthalmology), (4) industrial NDT and environmental monitoring expansion. Key strategic imperatives for suppliers: (1) invest in flexible MUT manufacturing processes and yield improvement, (2) develop higher-performance piezoelectric materials (ScAlN, PZT thin films), (3) pursue vertical integration (MEMS fab + electronics design + system integration) to control cost and performance, (4) expand into wearable and NDT markets beyond medical imaging. For medical device manufacturers and healthcare systems, MUT technology enables a shift from centralized (radiology department, cart-based) to decentralized (primary care, clinic, home) ultrasound, improving access and reducing costs.
