Google has filed for a patent for a wearable smartwatch or a handheld device that is capable of extracting small blood samples from its users without using a needle to prick the patient’s skin.

Smartwatches are becoming increasingly popular as tools for monitoring heart rate, exercise and stress levels, and now Google is planning to develop a much more sophisticated type of smartwatch…one that draws blood. Google has filed a patent for a “needle-free blood draw” system that could be built into a wearable attached to someone’s wrist, or a hand-held device.


The patent filing describes its technology to use a micro particle that is blown into the patient’s skin using a high pressure gas barrel after which a tiny amount of blood sample is again sucked back from the patient into a low pressured barrel. This makes the process quicker and less messy than using a needle, or even a blood glucose meter, which administers a “pin prick” to the finger. Google suggests that the device could even entirely replace the glucose testers that are currently used by diabetics. The patent said, “Such an application might be used to draw a small amount of blood, for example, for a glucose test.”

Google, now Alphabet, filed the patent back on May 28th, 2014, and it was approved on December 3rd, 2015.
