A wearable that tests blood glucose without needles

Whenever I think of wearable technology these days, I don’t get quite as excited as I do thinking about smartphones. I guess it’s because wearable technology isn’t as versatile as actual smartphones and most of them are actually used with smartphones to do certain tasks. While smarthones are very versatile,that doesn’t mean wearables aren’t appealing. It just means they really have to find a strong niche to fill.

One area where wearables are being applied quite heavily is Health and their future in that niche seems pretty promising. They have become quite handy tools for people who like to track data of their running sessions. With my recent blood pressure problems, it would be nice to have a wristband that could check my blood pressure and pulse rate whenever I need to. But the health applications of wearables have an interesting future because they are going further than doing just these simple tasks.

One good example of this is the recent patent filed by Google (now called Alphabet) describing a system for drawing blood without the use of a needle. The needle-less concept isn’t new since it dates back to the days of Star Trek and has had working prototypes since a few years ago. This system could be used either on a hand held device or a wearable. Having a wearable that can do this sort of thing is pretty new and exciting.

The system uses a micro-particle moving at high velocity due to a surge of gas to puncture the skin. Once the blood comes out, it is sucked up into a barrel like a vacuum. Just like other similar technology that doesn’t use needles, it’s supposed to be quick and painless.

This technology would be very useful for diabetics, since they often need to draw blood to test their blood glucose. This technology not only offers a quick and painless way to do it but also a way to do it on the go. Perhaps this could even test your blood glucose automatically on a regular basis, alerting you if the levels have gone too high or too low so you could take immediate action. Of course this system could possibly be used to test blood for other things, making this technology a big asset for more accessible health care around the world.

The next step would be a wearable that actually administer medication or insulin when you need it. It’s things like this that make monitoring the advancements in technology exciting.
