The SenseWear® Armband

Activity and Life Style Monitoring

The versatile, extensively validated, multi-sensory activity and life style monitor

The SenseWear® body monitoring system offers amazingly detailed information about the test person's life style, about his/her physical activity, rest and sleep times, energy expenditure; all this information being comfortably gathered under “free living” conditions, recorded and analyzed. By continuous sensory tracking of the wearer’s thermogenesis, not only activity, but also inactivity, particularly relevant to our modern life style, can be collected, analyzed, and exactly related to energy levels such as Resting Metabolic Rate (RMR).

The Monitoring System comprises the SenseWear® MF Armband, an extensively validated medical product, comfortably worn on the upper arm. Continuously acquiring a stream of high-resolution physiological data over a period of up to 28 days, the multi-sensory armband records, averages, and stores the data in its internal memory. As an essential part of the Monitoring System, the SenseWear® software, which can be installed on practically any PC or notebook under MS Windows®, analyzes the recorded information, and organizes the results into graphs and reports. Over any selected period of time, the wearer’s energy expenditure (calories burned), physical activity level (PAL), duration and level of physical activity, number of steps, distance, rest and sleep times and other lifestyle related parameters can be documented.

The slim design of the SenseWear Armband and its low weight of only 45 grams including the elastic strap, warrant uncompromising “wearability” under most “free living” conditions. Discreetly worn under clothing on the upper arm, the monitor can also analyze rest and sleep by evaluating thermogenesis, the heat generated and dissipated from the body, a unique feature other activity monitors cannot offer. These specifications lead to an excellent wearer compliance with per day recording times of typically 95%, assuring robust data consistency and safety. Proven in a broad range of applications, structured programs, and scientific studies, the Armband is applied by clinicians, researchers, personal trainers, dieticians, weight management consultants, research institutions, practices, hospitals, as well as fitness and wellness facilities worldwide.

Excellent “wearability” and wearer compliance

The typical wear and recording times of up to 23 hours ensure higher statistical safety.

Manipulation excluded

Skin sensors detect on-body and off-body times with certainty. Not turning on or off required.

Reliable detection of low activity, rest, and sleep

Multi-sensory approach and evaluation of thermo-genesis ensure unprecedented accuracy at all levels of energy expenditure.

Data scaling

All parameters are scaled to commonly used physical dimensions.

Artificial intelligence

Evaluation algorithms are based on artificial intelligence (machine learning, neural networks) trained on reference modalities, e.g. indirect calorimetry or doubly labeled water, as well as on annotated data attained under free living conditions by tens of thousands of individuals (data mining).


The wearable monitor contains four physiological sensors able to identify the full range of physical activities and inactivity, making it the ideal tool in a multitude of applications.

Affordable yet highly accurate

Calorimeters may be precise, but are demanding instruments not suitable for long-term recording. Actigraphs, pedometers, and accelerometers may be less expensive, but often less accurate or even not applicable. The SenseWear® armband though is both, affordable and accurate.


The slim ergonomic form factor of the SenseWear® armband does not interfere with daily activities, may it be work, leisure, exercise, rest or even sleep. The monitor can be worn under clothing, for any duration from 20 minutes to 28 days, practically unfelt by the wearer and unnoticed by his environment.

Activity monitoring can’t be made easier

The armband features a veritable simple application: Just slide the low profile armband over the upper arm. That’s it. Upon sensing skin contact, the armband starts recording automatically and turns off automatically when taken off.

SenseWear® Armband Containing Four Physiological Sensors:

  • Skin temperature
    senses the body surface temperature
  • Galvanic skin reaction (GSR)
    senses the skin impedance (stress, perspiration)
  • Heat flux
    senses the amount of heat dissipated from the body
  • Accelerometry in three axes
    senses movement and body position

Advanced Algorithms Allow Access to a Host of Life Style Parameters

  • Total energy expenditure (kcal)
  • Active energy expenditure (kcal)
  • Resting energy expenditure (RMR) (kcal)
  • Physical Activity Level (PAL)
  • Metabolic Equivalent Units (METS)
  • Number of steps
  • Total Distance (m)
  • Physical Activity Duration (h:m)
  • Lying down time (h:m)
  • Sleep time, Sleep Efficiency

Attain New Insights into Activity Patterns and Life Style of Test Persons

With the SenseWear® software, data recorded on the SenseWear Armband can easily be transfered to your PC. Sophisticated software technology based on artificial intelligence analyzes and documents results that you can annotate and share with your peers, clients, or patients.

Generating graphs and reports

SenseWear® Professional facilitates the thorough evaluation of your patient’s or test person’s life style, physical activity, rest and sleep patterns, allowing you new insights based on evidence rather than estimation by cumbersome and error prone diaries or logs. Solid physiological data, with no need to assume or extrapolate, allow robust statistics, essentially contributing to your scientific work.

The applications of the Body Monitoring System are numerous and broad. Already thousands of structured professional, clinical, and research programs and several hundred studies benefited from implementing the SenseWear® Armband. Our reference list comprises internationally renowned institutions with applications in every imaginable area of medicine, sports science, rehabilitation, and research.
You too can profit from an affordable, accurate, wearable method of monitoring physical activity and lifestyle minute by minute, outside the confines of a lab or physician’s office. The SenseWear® system has proven to be indispensable in any program that needs to track, monitor, and analyze energy expenditure, lifestyle, quality of life, activity patterns, stress levels, resting behavior, sleep efficiency or other important life style related data.

Regular exercise and physical activity continue to be a key factor in preventing serious medical conditions like obesity, cardiovascular disease, diabetes, and other chronic illnesses. The SenseWear® Armband bridges the gap between professional recommendations of a physician or trainer, and the ability of the patient or client to understand, self-monitor, and ultimately adhere to necessary life style changes, documented black on white in a concise and easy-to-understand format. Scientific studies indicate that the use of the Armband in structured programs can lead to more physical activity and considerably higher weight loss than in controls1.
