A new sweat meter which helps in quickly spotting low blood glucose levels has been developed by researchers at University of Oslo and the National Hospital of Norway.
This non-invasive method is beneficial in averting potential hypoglycemia. Extremely low blood sugar levels can even be life threatening, and in that sense the sweat sensors can immediately alert the user of low blood sugar levels so that urgent medical attention is sought before it gets too late.
Often, diabetics may not receive any warning signs of falling blood sugar levels. This can cause the victims to suddenly lose consciousness.
The sweat meter uses alternating current and transmits negligible electrical current via the outer part of the skin, into the sweat glands and further onto the skin surface again. As sweat contains salts and waters it is a good conductor of electricity.
When the blood sugar is low, the sweat meter is designed to send a warning about crashing blood sugar levels to a mobile phone so that immediate help can be provided.
