Bio-Shirt

The BioShirt is composed of two parts: a specially designed shirt and a monitoring system that weighs about just 20 grams including a battery. The battery life is roughly three and a half hours but it will be prolonged to approximately five hours, the average running time of recreational marathoners. People wearing BioShirt will be able to know their temperatures, heart rates and speeds while running on a real-time basis using a wristwatch-type miniature computer enabled by Bluetooth. When any of the three data types hits a ceiling configured in advance, a warning sign will let marathoners know it is time to stop running and take a rest.
