Google recently filed a patent application that provides details about a device for diabetics that would be able to draw blood and monitor blood sugar levels without the use of a needle.

While there are several painless systems in place for diabetics that use skin sensors or saliva to measure glucose, Google's patent for a blood-drawing wearable imagines that pressurized gas can be used to pierce the skin and procure only a "micro-emergence" of blood.

The concept has definite appeal for diabetic patients who are required to check their glucose levels at multiple points in the day. But looking beyond those with diabetes, the wearable may also prove to be of use for measuring other aspects of an individual's health, such as levels of hormones, protein or enzymes.
