Skin Temperature Monitoring

Posted on

New - Integrated IR sensor

Add skin temperature readings to the wide range of high quality signals captured by the Move 4 and EcgMove 4.

The IR sensor allows researchers to:

  • analyse individual circadian phases in the daily routine
  • monitor the increase of skin temperature fluctuation in sleep research
  • as a trigger for subjective data acquisition(questionnaires using Interactive Ambulatory Assessment)

    • Recommendations for skin temperatur monitoring



    IR Move 4

    New features that will amaze you in January 2024

    Posted on

    New sensor integrations and data transmissions.

    Customer requests and technical improvements are continuously taken up by movisens and incorporated into our products.

    • Accurately measure skin temperature! The Move 4 and EcgMove 4 are now available asstandard IR (infrared) versions. This enables the continuous acquisition of skin temperature in addition to the wide array of signals recorded.
    • View data in real time! Live-streaming of EDA data now possible with ourEdaMove 4.

    How does our heart behave under water?

    Cuore e Subacquea

    We're excited to support Giuseppe Di Tursi from Politecnico di Milano in his explorative research study "CUORE E SUBACQUEA" on cardiac physiology during immersion with our ECG sensors. This is the first study of its kind focused on assessing the feasibility to monitor the Electrocardiogram and Seismocardiogram (i.e. the measurement of chest’s vibrations induced by cardiac mechanical activity) during a diving session.
    The main goal and the innovation of this investigation stands in evaluating and quantifying the spontaneous adaptation of myocardial mechanics to the underwater environment.

    We're very excited about the upcoming results of this study and look forward to the further cooperation with Politecnico di Milano.

    ISAPA Move 4 Starter Set Winner

    As part of our ISAPA Break Session event, movisens held a Raffle to win a Move 4 Starter Set. Out of numerous participants we chose Merja Rantakokko from JAMK University in Finland as the winner!
    Congratulations!
    We wish Merja a lot of success with our Move 4 for her upcoming research work and look forward to reporting on her results in the near future.

    The meaning of Move 4 as Inertial measurement units (IMUs)

    Posted on

    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 newly published paper (How We Found Our IMU: Guidelines to IMU Selection and a Comparison of Seven IMUs for Pervasive Healthcare Applications) shows that also in gait analysis the sensor Move 4 of movisens supplies outstanding results!

    Validating Accelerometers for the Assessment of Body Position and Sedentary Behavior

    Posted on

    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.
