Biometric monitoring of footstep and heart rate using wireless inertial sensors

Conference Paper


Abstract


  • Inertial sensors are widely used for a variety of biomedical

    applications, such as human activity monitoring. We present a

    wireless biomedical monitoring network used for measuring

    footstep parameters and the heart rate of a person. The wireless

    biomedical monitoring network uses inertial sensors to record

    and monitor heart rate and consists of multiple monitoring

    nodes placed on a person, that communicate with a base node.

    The monitoring nodes placed on a person’s ankle measure the

    acceleration generated during a footstep. By analysing this

    data, we are able to determine the average footstep length and

    walking velocity to be 80cm and the average walking speed to

    be 1m/s which corresponds to results found by existing studies.

    A monitoring node placed on the right Carotid artery in the

    neck region was able to measure the vibrations generated by

    the movement of blood. Analysis of the acceleration signals

    generated by the pressure pulse showed that it was possible to

    determine the heart rate of the person. We found that a sitting

    person had a heart rate of 75 BPM, which was confirmed by an

    electrocardiogram device. Further areas of investigation

    involve improving the sensitivity of the monitoring node’s

    accelerometer sensor by using a diaphragm and also to measure

    a person’s blood pressure using inertial sensing.
