- Patch is made from super-thin but ultra-strong graphene and gold
- It soaks up sweat and analysis its contents to ascertain blood sugar levels
- If they rise too high, tiny needles release the diabetes drug metformin
- Is hoped the patch could be designed to release insulin, replacing jabs
A patch that measures sugar in a diabetic’s sweat could spell an end to painful insulin injections and finger prick tests.
Scientists have created an electronic-packed wristband that soaks up perspiration and analyses its contents.
The patch is also studded with tiny drug-filled needles, and if sugar levels are judged to be too high, these inject the diabetes medicine metformin.
The wristband, which is made graphene, a super-thin but ultra-strong material, and gold, accurately read the blood sugar levels of two healthy men.
