This Korean Times article says “amateur marathoners sometimes fail to pace themselves during the long, 42.195-kilometer course. This is very dangerous and can even lead to a runner’s death. To reduce the risk, a team of Korean scientists has developed wearable computing ware, called BioShirt, which warns runners who try to exceed their limits. The team, led by Kim Seung-hwan at the state-backed Electronics and Telecommunications Research Institute, yesterday unveiled BioShirt at the ongoing National Sports Festival. Several sprinters tested the BioShirt suits, which measure their heartbeats, temperature and running speeds at the 87th annual event in North Kyongsang Province.
“BioShirt is a mobile physical data monitoring device. We are staging field tests with sprinters to check whether or not the system works,” Kim said. “After checking this system’s viability via the pilot run, we plan to commercialize it late next year. Our immediate target is the nation’s millions of amateur marathoners,” Kim said”.
