Newly designed BioShirt, for marathon runners and running professionals, will assist runners in evaluating stats, and preventing overexertion. Korean scientists have developed “computing ware” with a monitoring system that weighs only 20 grams including the battery.
People wearing the BioShirt will be able to monitor their temperatures, heart rates and speeds while running on a real-time basis using a wristwatch-type miniature computer enabled by Bluetooth
