It seems like I report on this same story at least four times a year, but at least this time they talk a little bit more about the technology. As reported in Technology Review (okay, actually it’s from a piece by Ada Brunstein in the latest issue of the Atlantic (“The Little Black Piezoelectric Dress“)). From the story:
According to the designer Amanda Parkes, among the most important functions of technologically enhanced designer wear are power generation and storage. Parkes designed the Piezing, a dress that uses piezoelectric discs and film to harness the body’s movement for electrical power, which is stored in a battery near the belly button. (Piezoelectric materials use vibrations from movement to generate electricity.) The battery can then be used to charge a favorite device. Elena Corchero’s exquisite parasols and fans are adorned with intricate embroidery. But solar cells, conductive thread, and batteries give her old-school style a modern twist: Corchero’s Light Gown is a sexy nightie that turns into a night-light when hung on its charger-hook.
