“We currently have tiny computers in our pockets and on our wrists, and in the future we might have them in our bloodstreams. At a tech conference last week, Jawbone CEO Hosain Rahman said his company is looking into developing ingestible health sensors that could go deeper — literally — than Jawbone’s Up line of fitness and sleep trackers. You’d swallow the sensor, and it would collect and analyze your data.
Rahman suggested there could be shorter-term sensors that you swallow and later “pass,” and others that would stick around in your blood to keep tabs on things like circulation or blood-alcohol content. Maybe such an ingestible could communicate with your car, rendering it useless if you attempt to drive while over the legal limit.”.
