At the recent mHealth Summit near Washington, D.C., Fool analysts Rex Moore and Max Macaluso chatted with Robert McCray of the Wireless-Life Sciences Alliance. In this video, Rob explains Johnson & Johnson's efforts.

Max Macaluso: Let's start off with Johnson & Johnson, which is one of the best-known and probably biggest health care companies out there. It has a pretty robust pharmaceutical division, a medical device division, and also consumer health -- Band-Aids and Tylenol.

What are they doing with wireless technology?

Robert McCray: I can't speak to it completely, because as you know, J&J is over 250 separate companies; each one with their general manager and their business requirements.

What they have done and announced as a lead project is in therapeutic compliance. This is a B2B2C model, designed to use health care applications -- digital health -- to increase the compliance of patients with their therapeutic regimens, because that's a big problem in health care, and it's a big business opportunity for pharmaceutical companies.

It's the fact that about a third of our pharmaceuticals that are prescribed are never used. They're never purchased, they're never used -- so there's a missing revenue opportunity, and people don't get better if they don't take these therapeutics.
