Google, not content with slurping all your personal details, now wants to suck your blood.
Well, kind of. And in a nice way: the company has filed a patent in the US for a system that extracts blood without using a needle.
Essentially, the device uses pressurised gas and a micro-particle to pierce the skin then suck a tiny amount of blood from your finger into a “negative pressure barrel”, with the filing suggesting the device could be used for testing blood sugar.
Sounds a little squeamish? Well don’t worry: Google says the device will only take a “micro-emergence of blood”, which sounds OK to us.
