Wearable technologies are revolutionizing health care, but design limitations in adhesive-based personal monitors have kept them from meeting their full potential.

A new University of Arizona study, published in Nature Communications, describes a longer-lasting, 3D-printed, adhesive-free wearable capable of providing a more comprehensive picture of a user’s physiological state.

The device, which measures water vapor and skin emissions of gases, continuously tracks and logs physiological data associated with dehydration, metabolic shifts and stress levels.
