The global actigraphy sensors and PSG devices market was valued at USD 1.15 billion in 2019 and is projected to expand at a CAGR of 5.1% over the forecast period. Key market drivers include the rising prevalence of insomnia, a higher incidence of sleep disturbances linked to stressful lifestyles, and growing awareness about the importance of sleep in maintaining a healthy daily routine
Actigraphy sensors, small wearable devices that track movements to assess sleep patterns, are being integrated into both clinical and consumer applications. Meanwhile, polysomnography devices, the gold standard for sleep study diagnosis, provide detailed data on sleep stages and physiological parameters such as heart rate, brain activity, and muscle tone. Together, these technologies are shaping the future of sleep diagnostics and therapeutic interventions.
Recent technological advancements in sensors and software, as well as a growing preference for home sleep monitoring systems, are expected to fuel market growth in the coming years. The shift towards more personalized and remote healthcare solutions further accelerates the adoption of these devices. Moreover, governments and healthcare organizations are prioritizing sleep disorder awareness, which contributes to the market’s expansion.

Market Segmentation:

By Product Type:

Actigraphy Sensors: These sensors use motion detection to monitor sleep activity. They are non-invasive, cost-effective, and can be worn comfortably on the wrist or ankle. The demand for actigraphy sensors is growing due to their application in both clinical settings and consumer health applications.

Polysomnography (PSG) Devices: These devices are used in sleep centers and hospitals to measure various physiological parameters during sleep. PSG devices remain the most accurate tool for diagnosing sleep disorders. They offer detailed data on brain waves, oxygen levels, heart rate, and muscle movements.

By Application:

Clinical Applications: Sleep disorders such as sleep apnea, insomnia, and restless leg syndrome require precise monitoring. PSG devices are widely used in clinical environments to diagnose these conditions, while actigraphy sensors are employed in both clinical settings and home use.

Consumer Applications: With growing awareness of the importance of sleep for overall health, consumer-grade actigraphy sensors are increasingly popular. These sensors are used in wearable devices that track sleep quality, helping users improve their sleep habits.

By End-User:

Hospitals and Sleep Centers: PSG devices are primarily used in these settings to diagnose complex sleep disorders. Hospitals remain a key market for PSG devices due to their precision and ability to collect multi-parameter data.

Home Care Settings: Actigraphy sensors are gaining popularity in home care, enabling individuals to monitor their sleep without visiting a sleep center. Home-based solutions allow patients to track their sleep patterns and share data remotely with healthcare providers.

By Region:

North America: The North American market holds a significant share due to the increasing prevalence of sleep disorders and the high adoption rate of advanced medical devices. The U.S. is a leader in both technological innovation and healthcare infrastructure, which benefits the market for PSG devices and actigraphy sensors.

Europe: Europe also exhibits strong growth, particularly in the UK, Germany, and France. Increasing healthcare awareness and the presence of major healthcare providers are fueling the demand for both PSG devices and actigraphy sensors.

Asia-Pacific: This region is expected to grow at the fastest pace due to rising disposable incomes, an aging population, and increasing awareness of sleep-related issues. Countries like Japan, China, and India are witnessing a surge in demand for home-use sleep monitoring devices.

Rest of the World: Latin America, the Middle East, and Africa are emerging markets where healthcare infrastructure is improving, thereby driving the need for sleep diagnostics devices.
