Apple also has hired Ravi Narasimhan, who was VP of R&D for Vital Connects.That company developed a disposable health monitor that can be used for three days monitoring a person's ECG, temperature, and movement. After three days, you simply toss the monitor. It doesn't take a Mensa member to figure out how Apple can use capabilities like that for the iWatch. The disposable monitor could end up being sold at Verizon this year using Big Red's mHealth brand.
Americans familiar and comfortable with technology are getting older, and as they age, using the same technology they grew up with to monitor their health seems like a sure thing business wise. That means we could see many health related sensors for the Apple iPhone, Apple iPad and the Apple iWatch.
Speaking of the timepiece, Apple has been rumored to be running into problems manufacturing the product, which is still expected to launch some time in the second half of this year.
