Soft fabric sensors and exosuits for running

Soft Fabric Sensors from Wyss Institute on Vimeo could be used to detect small movements in real time. Therefore we will see such fabric sensors for human articulation detection, exoskeletons and soft robotics.

Well, the power supply cable is okay while running on a treadmill, but how big must be battery pack to use the exosuit for 10 kilometer race?
