Patent attributes
In one example, an apparatus. includes a shoe having a sole with at least a portion of foam replaced with a composite polymeric foam, at least one probe disposed in the composite polymeric foam, a voltage detector coupled to the probe that detects voltage data generated by the composite polymeric foam, and a transformation module that converts voltage data generated by the composite polymeric foam in response to deformation events into GRF, acceleration, or pressure data. In another example, a method includes receiving voltage data produced by composite polymeric foam, the composite polymeric foam providing support and padding in the sole of a shoe, converting the voltage data to force data, comparing the force data to a profile, and transmitting, when the force data fails to fall within a threshold of the profile, a feedback signal to a physical feedback device, the feedback signal indicating a difference with the profile.
