For diabetics, pricking the finger or forearm to check blood glucose levels day after day can be painful, annoying and inconvenient. This gadget – the Photonic Glucose Sensor – was designed by Alain Poirier to make life a little easier and less painful for people with diabetes.

The PGS would work with a two-piece system consisting of an armband and a strap-on sensor. Near-infrared light technology would measure the wearer’s blood glucose levels every five minutes to ensure that the blood sugar stays within acceptable levels all day.

The device is rechargeable and can run for up to 30 hours on a single charge. That means that even if you go out dancing after work, you won’t have to worry about rushing home to test your blood or recharge your device. You will, however, still have to content with wearing two bulky pieces of plastic on your body all day, every day.
