This patch could test blood sugar and deliver insulin without using any needlesany Living with diabetes and squeamish about needles? You’ll love this new invention from a doctor in South Korea.

Currently, many diabetics face the ordeal of multiple daily finger pricks in order to test blood-sugar levels and administer insulin as needed. To try and eliminate this painful hassle, Professor Kim Dae-hyeong of Seoul National University has developed a wearable, see-through patch that can detect sugar levels and deliver medication, as needed, to the wearer.  

Here’s how it works: sensors in the patch collect information on temperature, pH and blood sugar levels, relaying that information to an app. The app then makes calculations and, if the patients needs it, sends a message to the patch to deliver medication through the use of its painless microneedles.

If all this sounds too good to be true, that’s because it is: Kim expects his patch won’t be available to the public for another five years. Still, it’s always exciting to see new developments in the field of diabetic health management—especially ones that could get rid of those nasty needles!
