Box for use as smart card for energy recovery in clothing e.g. shoe soles, has capacitors placed between bottom part and lid, where capacity of capacitors is varied such that electric power is obtained from work and stored in buffer memory

摘要

The box has an edge part maintaining altitude while recovering energy. Multiple capacitors are placed between bottom part (5) and a lid (6), where capacity of the capacitors is varied such that electric power is obtained from mechanical work and stored in a buffer memory. A spring element i.e. resilient perforated plate (7), is arranged in a box body. Droplets (3) are deformed by applying force (8), where return force is produced by the resilient perforated plate, and the bottom part and the droplets are passed into holes. An independent claim is also included for a method for creating a box.
