The MOX is a smart activity monitoring platform. The compact and unobtrusive MOX device can be worn on several places of the subject’s body (waist, lower back, pockets, thigh, bra etc) to measure accurately the level of physical activity and/or posture movement during daily living activities. The small, lightweight device can analyse the measured movement signals and transmit them wirelessly to a user interface.

Changes in health and care

Healthcare is changing: increasing costs and a changing population require a shift in the organisation of our healthcare systems. It is increasingly becoming important that the entire chain around health and care is optimally organized. The focus shifts from treatment in a care center to prevention outside the care institute. In case people do become ill, added value is achieved by providing care in the home situation. Researchers, care providers and companies have numerous ideas on how to improve healthcare. Modern technology offers the opportunities to realize these ideas. An important role can be attributed to monitoring technology, which measures relevant body- and behavior parameters on which new care and research applications can be based.

Open products, open technology

Every care or research application poses specific requirements to the technology that is being used. Especially research related to chronic diseases, such as diabetes, obesities, heart failure and pulmonary diseases, requires highly accurate instruments to determine the physical state of subjects during trials. An important parameter to determine the physical state of the subject is measuring the level of physical activity during daily living. In such applications it is of value that the raw data is accessible for analysis or processing with customer specific algorithms. Maastricht Instruments delivers open products that researchers and care providers can embed optimally in their applications. The available technology platform can be efficiently tailored for companies that want to market an OEM or brand-specific product. The MOX technology has been developed in close cooperation with the Department of Movement Science of Maastricht UMC+, one of the leading research groups in the field of Human Movement Sciences. This partnership provides a unique opportunity for companies and care organisations.

MOX activity monitoring technology

The MOX is a smart activity monitoring platform. The compact and unobtrusive MOX device can be worn on several places of the subject’s body (waist, lower back, pockets, thigh, bra etc) to measure accurately the level of physical activity and/or posture movement during daily living activities. The small, lightweight device can analyse the measured signals and transmit them wirelessly to a user interface.

Mox activity monitor benefits

  • Raw data accessible.
  • High comfort.
  • Applicable for all ages and various conditions.
  • Store data in-device or transmit data real-time.

Unique treatment and research

The technology can be delivered in small quantities, which makes it an ideal tool for biomedical research. The technology can be integrated in a compact form factor, which enables researchers to gather data in real-life circumstances. The comfortable design has a positive effect on compliance levels in care applications. Furthermore, the technology is optimally suited to monitor persons in their home environment during longer periods of time. The unique combination of functionalities provides a solid base for realizing new applications in health, care and research. The platform can be tailored to your specific needs with custom analysis software or hardware specifications.

Application of MOX technology

The MOX technology is developed specifically for use in care- and research applications. The system can be utilized to measure relevant body movements of a person during activities of daily living. The measurements can be transformed with algorithms to meaningful information for use in an app on a smartphone or tablet. A care provider can monitor the persons through an e-health portal. Maastricht Instruments offers a number of suitable digital platforms for this part of the application also. For use in research applications, the system can be connected to IDEEQ; the data visualization and analysis software program of Maastricht Instruments. The software contains functionality to readout the device and visualize, record and process the measured signals. As well offline as real-time analyses can be executed on the measured signals. The gathered data can be exported for processing in conventional software packages like Matlab or Excel.

Technology available as OEM and white label product

The MOX activity monitoring platform is a modular system for measuring movement. The system accurately measures the level of physical activity and posture movement of subjects by means of measuring the time varying 3D-accelerations. All raw data is stored on the internal memory for analysis afterwards. Algorithm output can be transmitted in real-time to a host system through Bluetooth™ technology. The data can be analyzed offline using the proprietary validated algorithms of Maastricht Instruments and or Maastricht UMC+ or using your own developed algorithms. The user interface module serves as a link to interaction elements. A compact battery powers the entire system. Several versions of the technology are currently available; a Bluetooth and Bluetooth Smart Activity Monitor suitable for connection to a smartphone and a USB Activity Monitor equipped with LED indicators. The technology is also available as OEM activity monitor electronics or as whitelabel activity monitoring device. The platform can be tailored to optimally match specific application requirements. Examples of current research applications are: physical activity monitoring of patients, eHealth, ADL monitoring, daily activity monitoring, posture monitoring, fall-risk assessment of elderly and stumble & fall detection.
