University of Texas professor Shalini Prasad has developed an adhesive sensor that measures diabetes-associated compounds in small amounts of sweat.

Blood glucose levels, cortisol and interleukin-6 are detected in perspiration for one week with full signal integrity.  The device uses ambient sweat, created by the body with out stimulation.

The sensor can be placed anywhere on the skin and takes customized readings up to once an hour.  Data is sent to a user’s phone.

Prasad estimates that the sensors would cost 7 cents each if produced in bulk, making the technology truly accessible.
