Footwear or orthotic sole with microprocessor control of a bladder with …

This invention describes a shoe or orthotic sole that can actively change its cushioning and support. It uses bladders filled with a special magnetorheological fluid that thickens or thins when an electromagnetic field is applied. A small computer in the sole controls this field, allowing the sole's properties to be adjusted on the fly.

Why it matters: Miniaturization and power efficiency of embedded electronics have advanced significantly since 2021. This makes integrating the complex control system and power source into a wearable device more feasible.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMagnetorheological fluid, custom electronics, microprocessor control
