Rechargeable Washable BlueTooth Shoe Insoles

Howse about a simple 4 pressure sensor per insole which makes up a 8 way directional movement? With calibration for the difference in pressure between sitting and standing, for use either way at the check of a box? Transmission via bluetooth and powered by litium ion usb rechargeable batteries (like the little packs in the bluetooth ear pieces).
Insoles would be trimmable to size and washable (but not dryable). Just gimme 15% :lol: put little cell phone vibrators in the arches for haptic feedback...that would $%&# people up :twisted:
