This is inspiring. The cost can be brought down through use of soft and/or lightweight materials. For example, the use of textile based actuators. Good examples in link below:
You know what I am wondering, the accelerometers in phones are super small, cheap and there are some sensor systems that incorporate a ton of other sensors (whatever happened to Google's smart jacket they were making with Levis)
Anyway, it would be very interesting to have a textile with a fabric of accelerometers woven into the fabric... Solar panels on the thighs and what not to power the sensors... with a compression-heel in a shoe / boot to ad more power with every step.
Anyone know how much power an accelerometer takes and if you can wire a matrix of them together to a set of controllers that all they do is capture the telemetry from the sensors?

These things are not for the near term so really impressed by this story.
