WASHINGTON, DC —
It's not a "Star Trek" tricorder, but by hooking a variety of gadgets onto a smartphone you could almost get a complete physical without the paper gown or even a visit to the doctor's office.
Blood pressure? Just plug the arm cuff into the phone for a quick reading.
Heart OK? Put your fingers in the right spot, and the squiggly rhythm of an EKG appears on the phone's screen.
Plug in a few more devices and you could have photos of your eardrum (Look, no infection!) and the back of your eye, listen to your heartbeat, chart your lung function, even get a sonogram.
If this sounds like a little too much DIY medical care, well, the idea isn't to self-diagnose with Dr. iPhone. But companies are rapidly developingminiature medical devices that tap the power of the ubiquitous smartphone in hopes of changing how people monitor their own health.
