In-body sensors could warn doctors

ABC News, May 20, 2008

In the next 10 to 20 years, the technology that allows us to use wireless headsets to chat on our cell phones could provide doctors with vital signs, according to a United Kingdom report. The report found that humans could one day have "in-body networks," a series of sensors implanted in a patient's body to let doctors monitor the body remotely. The report also predicted the creation of "on-body monitors," wearable devices that would send vital information via Bluetooth or Wi-Fi to a portable monitor such as a watch or a cell phone. The technologies are being researched in United Kingdom universities.
