Eric Topol: The wireless future of medicine

Eric Topol says we'll soon use our smartphones to monitor our vital signs and chronic conditions. At TEDMED, he highlights several of the most important wireless devices in medicine's future -- all helping to keep more of us out of hospital beds.

Much of the new data is likely to be streamed via wireless networks to and from smart phones, from small sensors in and around the human body. See the TED talk for more info.
