The answer to all your medical problems may just be in your sweat. Scientists at Northwestern University have developed a tiny, flexible skin patch that has the capability of detecting diseases.

Human sweat contains many of the same bio-markers that are found in our blood. The skin patch technology finally capitalizes on this as it analyzes our body, without the pricking of a needle. The patch is simply placed on users and analyzes their sweat in order to produce some telling results. The skin patch can alert the user to drink more water, consume more electrolytes, or detect a bio-marker for cystic fibrosis.

Scientists hope that the patch can be used to diagnose other diseases in the future. If the technology advances, the simple patch can reduce the need for invasive blood tests, making visits to the doctor's office more pleasant and approachable.
