Google has taken over your screens, and now the company plans to get in your bloodstream. Andrew Conrad, a molecular biologist, has been working with Google X to build an ingestible nanoparticle pills that floats in the bloodstream and emits signals if something is wrong. The alert is transmitted to a wristband device. It will "do a continous measurement of key biological markers through non-invasive devices," says Conrad. "And we would do that by miniaturizing electronics." Google X Life Sciences consists of more than 100 researchers investigating the connection between health and technology.
