Once I reached further into the dusty recesses of my brain, I remembered that I always had independent measures of displacement to go along with time-vs-strain measures. > and accelerometers would be great.

Nick Now it's getting tricky - though a sufficiently sensitive pressure measuring fabric could suffice and Bernoulli can help us deduce the local velocity.
