Hate needles? Google's smartwatch will analyse your blood prick-free

Google has filed a patent application for its new smartwatch that is able to draw blood from the user's wrist for testing and analysis without the dreaded prick. The blood is drawn through a painless procedure involving micro-particles and does not require needles.

Google has been involved in several projects that are aimed at fighting diabetes and other severe ailments. Since blood testing and analysis is a regular process, Google's new smartwatch aims to remove the pain factor by replacing needles with a new technology.

The new blood-sucking technology involves a micro-particle being shot into the wearer's skin through a high pressure gas barrel and a tiny amount of blood sucked back into a low pressure barrel. The blood thus drawn can be used for several tests, analysis and diagnostics.

If you are a diabetes patient, this new technology will let you go through regular blood testing without having to go for injections, thus saving you from pain and letting you walk the extra mile to get yourself treated quicker and more effectively.

Google has also built a new smart contact lens which can analyse sugar levels from data collected from tear fluid in the wearer's eye. The smart lens contains micro sensors and computer processing chip sets for this purpose.

Google's erstwhile research and development unit for health science projects is now under the aegis of its parent-unit Alphabet. Life Science, a health care start-up under Alphabet, is partnering with Novartis to perfect the smart contact lens for commercial use.

“Our dream is to use the latest technology in the miniaturisation of electronics to help improve the quality of life for millions of people. We are very excited to work with Novartis to make this dream come true," said Google's co-founder Serget Brin whehn the deal was struck.

The lens could also be used to help improve poor eyesight and even work to counteract the effects of cataracts.
