My idea is to create a new Wearable T-shirt 2.0 to track performances of athletes and non athletes and give performance datas to a software related with an app. Plus the platform can give you the possibility to choose a trainer in your area and start a program with him or virtually or phisically supported by your t-shirt. I am doing the prototype and i have just made a market research and thought about how to merchandise this with also new technologies like bitcoins and also how to put it of crowdfunding. Join me this could be a great product. in the next 3 years the wearables market will grow exponentially and people are more open minded to buy IoT products now.
