The impact indicator is a perfect example of a new market opportunity and not just for contact sports. How about a discount on car insurance if you wear an impact monitor while driving. The possibilities are mind scrambling..
Although the market may not be quite ready for some of these devices, there is a great deal of opportunity to be seized by companies looking into wearables. I especially think, given the importance of safety concerns--especially for children and young athletes---that the brain-sensing headband and the wearable locator and phone for kids could be onto something. The headband addresses head trauma and other types of injury which are increasingly on peopole's minds these days and there is always a concern for the possibility of children going missing.
