Google wants your blood

Such a clickbait way to say that Google is developing a way to draw blood needle free.

Probably the title needs to be changed to "Google has filed a patent for a 'needle-free blood draw'".

Sounds kind of like the old vaccine airguns, but deliberately taking a sample instead of accidentally: https://en.m.wikipedia.org/wiki/Jet_injector

Could this be like the hypo spray in Star Trek? Assuming it can work in reverse.
