The Cardioleaf electronic module snaps onto the shirt with 4 standard snaps. Simply turn off the device, un-snap the unit and throw the shirt in the wash. My FIT shirt shown in the video survived 3 washings.
It's not a product.... YET. Very cool, and I can see tons of market potential for this. Say the technology was integrated into Nike or Addidas sportswear... they could easily market this as a must have for athletes to track and monitor their own fitness, etc.
The only question is... how do you wash it without killing the sensors??
