Market Overview
The global actigraphy sensors and PSG devices market was valued at USD 1.15 billion in 2019 and is expected to grow at a CAGR of 5.1% during the forecast period.
Sleep disorders, including obstructive sleep apnea, insomnia, circadian rhythm disorders, and movement-related sleep conditions, are becoming major public health concerns worldwide. Actigraphy sensors—worn on the wrist or body—provide non-invasive monitoring of sleep and activity patterns, while PSG devices remain the clinical standard for detailed sleep assessment. Advances in battery life, miniaturized sensors, cloud-based analytics, and AI-driven scoring have enabled hybrid diagnostic models that combine ambulatory PSG with actigraphy for screening, treatment monitoring, and long-term follow-up.
Market Scope
- Device Types – Wrist actigraphy devices, ambulatory/home PSG kits (portable recorders and sensors), and in-lab PSG systems.
- End Users – Hospitals, sleep centers, home healthcare providers, and research institutions.
- Applications – Diagnostic screening, long-term sleep monitoring, treatment adherence tracking, and clinical research.
- Technology Stacks – Sensor hardware, signal processing and AI algorithms, cloud analytics, and EHR integration.
Market Opportunities
- Ambulatory and Hybrid Diagnostics – Combining portable PSG systems with actigraphy allows rapid scaling of diagnostics with high-quality clinical data.
- AI and Analytics Solutions – Regulatory-cleared algorithms converting raw sensor data into actionable sleep metrics can be bundled as analytics services.
- Integration with Chronic-Care Programs – Embedding long-term sleep monitoring into treatment pathways for cardiovascular, neurodegenerative, and mental health conditions creates recurring revenue opportunities.
- Emerging Markets – Fast-growing regions are adopting cost-effective portable PSG and actigraphy solutions for home-based sleep monitoring.
Regional Analysis
- North America – The largest market, driven by well-established sleep-medicine infrastructure, favorable reimbursement, and high adoption of both clinical PSG and actigraphy devices.
- Europe – Strong clinical adoption in Western Europe with growing ambulatory programs in Central and Eastern Europe. Regulatory support for medical wearables encourages growth.
- Asia-Pacific – The fastest-growing region due to expanding healthcare infrastructure, rising awareness of sleep disorders, and increased adoption of mobile health solutions.
- Latin America & MEA – Opportunities exist primarily in private clinics and urban hospitals. Telehealth expansion supports growth in these regions.
