Found this gem a little while ago. MC10 is a company making wearable monitoring devices and is very sports optimization focused. One is a head trauma impact sensor cap thing and the other is like a wearable tattoo(bio stamp) that monitors things in the body
"Bio skin" goes on like a temp tattooo but no adhesives. Supposed to work like a geckos feet

The "Reebok Checklight" head impact sensor cap for all sports that deal with hits to the head. Boxing, football, hockey, etc
