Acid-Detecting Biomedical Transmitter Available

SEWilco writes: "This Medtronic press release announces a wireless stomach monitor. Actually, it's fastened internally ( and is less unpleasant than the older testing method) just above the stomach to detect acid getting to the wrong place. Results are sent to an external device, later uploaded for analysis. It's not as elaborate as the swallowable camera we've discussed, but this has been commercially introduced so there will be people walking around with these...for the few days that they last. It's available in the trendy translucent case design, but by prescription only. I suspect the over-the-counter market is rather small."
