Technology Overview

Our noninvasive, objective and ambulatory monitoring devices have been used by a variety of researchers in a variety of research applications

Actigraphy (Actiwatch and PAM-RL)
Actigraphy can help you assess the sleep/wake patterns of a variety of patients with various sleep complaints. It is an objective tool to gain insight into real-world sleep/wake and daytime activity and is a complementary or adjunct to a polysomnogram or subjective paper diary.

Highlights of actigraphy technology:

  • Noninvasive – the absence of wires or uncomfortable sensor attachments help provide an effortless patient experience
  • Objective – provides an accurate representation of sleep/wake history
  • Ambulatory – real-world sleep/wake data is collected during everyday living
  • Multiple night monitoring – continuous monitoring for weeks or months allows for a better assessment of sleep/wake patterns
  • Easy to comply with – "wear it and forget it" technology fits easily and seamlessly into everyday life
  • Low daily cost – reusable devices, worn for multiple days, provide valuable data for assessment and treatment programs
  • Rugged dependability – active patients can be monitored with confidence


    • The data provided by actigraphy devices has a variety of applications in the fields of:

  • Sleep medicine and sleep disorder research
  • Circadian rhythm disorders research
  • Daytime activity research

    Accelerometry (Actical)
    Accelerometry is an objective, ambulatory monitoring method for tracking, over time, the intensity and duration of an individual's:

  • Physical activity
  • Energy expenditure
  • Heart rate
  • Step count

    • What accelerometry offers:

  • Accurate validated algorithm – correlates 98.5% to doubly-labeled water
  • Noninvasive – patients wear it and forget it
  • Multiple day and night monitoring – continuous monitoring for days or weeks allows for a better assessment of activity patterns
  • Selective data analysis – enables specific time periods to be captured and analyzed
  • Objective – provides a true and accurate representation of physical activity and energy expenditure
  • Ambulatory – real-world data is collected during everyday living and activity
  • Unobtrusive – small size and easy to use – suitable for a wide variety of applications
  • Easy to comply – device fits easily and seamlessly into everyday life
  • Continuous – worn for multiple days; provides valuable data for assessment of treatment programs

    • The data provided by accelerometers has a variety of applications in the fields of:

  • General exercise and physical activity
  • Sports medicine
  • Nutrition
  • Large epidemiological studies
  • Obesity research and weight management
  • Wellness program assessment

    Telemetry (VitalSense)
    Telemetry is a convenient method to record and track a subject's physiology - core body temperature, dermal temperature, and heart and respiration rate – all without wires and probes over time.

    What telemetric monitoring offers:

  • Unobtrusive – wireless sensors eliminate need for probes
  • Ambulatory – allows for monitoring of patients in their natural environment
  • 24/7, real-world subject monitoring
  • Data storing in nonvolatile memory

    • The data provided by telemetric monitoring has a variety of applications in the fields of:

  • Clinical trials
  • Military medicine and training
  • Pre- or post-operative outpatient monitoring
  • Healthcare telemedicine
  • Sports medicine
  • Hazardous occupations
