Scientists have developed a self powered paper based wearable sensor that could allow diabetics to measure glucose levels from sweat during exercise.
Today’s most wide-spread methods for glucose self testing involve monitoring glucose levels in blood. Conventional measurements are ,however ,not suitable for preventing ‘hypoglycemia, during exercise.

Researchers have now developed and demonstrated a self powered wearable and disposable patch that allows for non-invasive monitoring of glucose in human sweat!
This wearable single use bio-sensor integrates a vertically stacked paper based glucose/oxygen enzymatic fuel cell into a standard band-aid adhesive patch.
