Rejoice: measuring blood glucose no longer need to tie your finger

Diabetics must prick their fingers daily to test their blood sugar levels with an annoying blood drop. Tyra Kozlow, a British woman designer, came up with the Sense blood glucose measuring earrings, which combine a blood glucose machine with an earring, in hopes of making it acceptable to patients.

Sense is a stud-style earring that uses safe, high-frequency radio waves to read blood glucose levels in the earlobe. Users can simply turn on the pairing App on their smartphones to receive the signal and know the level of blood glucose at any Time, eliminating the need for needles and test strips, and reducing medical waste.
