Pervasive healthcare is among the most prominent fields of research with an increasing demand for IMUs.
Inertial measurement units (IMUs) are electronic devices that typically consist of a 3-axis accelerometer (which measures linear acceleration) and a 3-axis gyroscope (which measures angular velocity).
Typically, IMUs are used to track movement patterns or recognize activities of the user like gait analisis.
The respiration signal provides important information about mental and physical stress.
To assist a researcher’s project, we integrated a respiration sensor into our Move 4 which records the participants breathing rate via a chest strap and transmits this information directly via Bluetooth interface to the researcher's software.

The article "OREBA: A Dataset for Objectively Recognizing Eating Behaviour and Associated Intake“ (Rouast et al., 2020) shows a comprehensive multi-sensor recording of communal intake occasions for researchers interested in automatic detection of intake gestures.
Modern multi-sensors like the Move 4 provide researchers the ability to collect objectively a large dataset regarding the accelerometry and gyroscope-data. That is very important for automatic detection of intake gestures that is a key element of autonomic dietary monitoring. Read more and klick the article above.
As part of movisens' 10th anniversary, the best student project is being awarded a prize for the student and the supervisor. You can now register for this competition with your student project. Every successfully completed student project can take part in the competition. This also applies to former students who have successfully completed a student project together with movisens in the past 10 years.
There is growing evidence that sedentary behavior is a risk factor for mental health. Activity sensors play an important role in the investigation of sedentary behavior.
But how exactly do they measure sedentary activity, and where is the best place to measure it?
The following table gives a short overview of the validity of different activity sensors. Further information can be found in the article: Validating Accelerometers for the Assessment of Body Position and Sedentary Behavior.

Our mobile sensing webinar is now available free of charge to all interested parties. More helpful information about mobile sensing and movisens' applications can be found on our mobile sensing solutions page.
Ambulatory Assessment and Mobile Monitoring are the expertise of movisens. In order to support scientific work in these areas, movisens has been supporting student projects over the last 10 years by providing free loans of sensors and software.
Once again a study idea has been successfully carried out by an innovative project!
Students of the University of Lund examined the influence of integrated lighting systems in the office in relation to well-being and health.

If your research revolves around physical activity, we’ll show you how our activity sensors accurately record physical activity in everyday life.
Move 4 und LightMove 4 - Perfect tools for capturing physical activity
The activity sensor Move 4 from movisens allows a continuous, objective recording of physical activity for up to 4 weeks.
From the measurement parameters (3-axis acceleration, rotation rate and barometric pressure) we can calculate a multitude of categories and output parameters such as Physical Activity (PA), Sedentary Behaviour, Sleep, Energy Expenditure and Physical Activity Metrics.
The integrated pressure sensor improves both activity classification and the accuracy of energy expenditure estimation. For example, we can distinguish between normal walking and stair climbing.
A further advantage presented by the LightMove 4 model is an integrated light sensor. The data recorded by the light sensor allows the detection of the type of ambient light and also helps detect the intention to sleep.
The movisens team provides development expertise for researcher specific questions. We’re always happy to discuss your research project and see if we can tailor a solution for you.
Given repeated requests, we’ve integrated an IR Temperature sensor in our activity sensor Move 4 and our ECG and activity sensor EcgMove 4. This researcher specific customisation allows a continuous recording of the participant’s skin temperature.
movisensXS provides researchers easy access to the Mobile Sensing features of smartphones. The additional insights derived through Mobile Sensing add context to questionnaire data, and can help determine optimal times for interventions. This is useful for researchers of Interactive Ambulatory Assessment.
