A foot-based wearable system disposed proximate to the dorsalis pedis artery can detect cardiac and muscular activities. Utilizing flexible iontronic sensing (FITS) technology, a sensing array detects both cardiovascular functions, such as heart rate, ECG, and respiration and motion artifact signals with a spatial reference to muscular activities based on the orientation of the array. Individual tendon responses are analyzed and correlated to different pedal gestures, from which multi-channel signals can be used to distinguish different activities. Wearable articles of the invention include a platform to simultaneously analyze both vital signals and body activities from the cardiac waveforms and muscular responses in a natural and unnoticeable fashion. The data-collecting wearable system provides a means to assess personalized health and daily activities on a continuous basis.
