High-Tech Health Care.

The article focuses on wireless devices that can keep track of, diagnose and monitor our health. Picture a medical device that's used to link wirelessly to a cell phone that can communicate a person's blood pressure, blood sugar level or heart rate. Another idea is to use a "disposable wireless sensor" or "smart wireless Band-Aids" that can be used to measure such physiological information as skin temperature and blood oxygen levels, and communicate it to a cell phone. The market for wireless technology for medical uses in the United States was about $300 million as of 2003, with a compounded annual growth rate of 18 percent.
