Holmes had then just spent the summer working in a lab at the Genome Institute in Singapore, a post she had been able to fill thanks to having learned Mandarin in her spare hours as a Houston teenager. Upon returning to Palo Alto, she showed Robertson a patent application she had just written. As a freshman, Holmes had taken Robertson’s seminar on advanced drug-delivery devices–things like patches, pills, and even a contact-lens-like film that secreted glaucoma medication–but now she had invented one the likes of which Robertson had never conceived. It was a wearable patch that, in addition to administering a drug, would monitor variables in the patient’s blood to see if the therapy was having the desired effect, and adjust the dosage accordingly.

“I remember her saying, ‘And we could put a cellphone chip on it, and it could telemeter out to the doctor or the patient what was going on,’ ” Robertson recounts. “And I kind of kicked myself. I’d consulted in this area for 30 years, but I’d never said, here we make all these gizmos that measure, and all these systems that deliver, but I never brought the two together.”
