Millions of people, ranging from children to professional athletes, are treated annually for sports injuries. The most severe injuries often come from playing contact sports.
To better understand the forces the body experiences during contact motions and objectively analyze tackling form, a pressure sensitive wearable made from piezoresistive fabrics was developed and tested on humans. This device was able to collect data during normal practices or games, and process sensor readouts in real time.
The shirt in action. A slow-motion tackle is performed by an experienced contact sports athlete, and the resulting forces plotted as contact is made.
Areas marked in red are the most commonly injured torso regions during activity. Blue regions mark where safe, proper contact should occur. The circled areas on the skeleton translate to the highlighted regions on the shirt.
