If artificial intelligence in healthcare brings to mind visions of robot surgeons, BioIntelliSense's stick-on sensor is bound to be a disappointment. Just three inches wide by one inch tall, this plastic and metal double hexagon was cleared last month by the United States Food and Drug Administration for remote monitoring of vital signs with medical-grade accuracy.

Doctors at UCHealth, which runs 12 Colorado hospitals, say the device will let them send patients home earlier while still monitoring their respiratory rate, resting heart rate, skin temperature and even body position.
