Athletes who use heart rate monitors know the exquisite pleasure of wearing a chest strap to pick up heart rate and other electrical signals. This invention out of Korea should eliminate the need for that sort of thing.
It’s the BioShirt, and it has sensors in it. The special monitoring system sends all sorts of information to a Bluetooth wristwatch computer, including heart rate, body temperature, and run speed. The battery life averages at 3.5 hours right now, which is sufficient for most runners, excluding the slower marathoners. Ultra runners should probably look elsewhere, since the battery length is expected to top out at 5 hours.
The company also points out that the BioShirt can be used as a normal monitoring system for non-runners and especially for hospital patients.
