Apple patent application details electromagnetic induction system for future Apple hardware

“Just as the auto industry is racing to find the perfect electric engine, the tech sector is in a similar race to find a better battery or a new energy source to extend the life of portable devices,” Jack Purcher reports for Patently Apple. “Being that Apple is the leading mobile devices company in the world today, they know all too well how important a breakthrough in this field may be. In today’s patent we see that Apple is exploring ways of building a miniature electromagnetic induction system right into future portable devices as a means of extending battery life.”

Purcher reports, “Apple’s patent is all about systems for harnessing power through electromagnetic induction utilizing printed coils. A system could include one or more moveable magnets adjacent to printed coils on a circuit. For example, a system could include one or more magnets that are operative to move alongside a circuit board that includes printed coils. The one or more magnets may move, for example, when a user shakes the system or when the user walks or runs while holding the device. The movement of the one or more magnets may create an electromotive force (e.g., a voltage) across the printed coils, and this force may be used to generate electric power.”

    1. Uh, not quite. Self-winding phones use weights in conjunction with the flywheel effect to mechanically tension springs to wind a watch. What is being described here is entirely different.

      Lose $200, go directly to Jail.

  1. Would need to be very sensitive so you wouldn’t have to actively “shake” the device. If it works for watches, then why not iPhones? There would, of course be a much higher generation of voltage needed.

  2. I was rather hoping, from the headline, that they were referring to some kind of contactless charging system. MagSafe, as good as it is, is still flawed in several ways (notably the connection point of the charging wire to the “brick”); of course, it’s not something that Apple could patent, so I understand that they’re not particularly interested in putting money into making things easier for their customers.

    (Funny – there used to be a computer company with a fruit-shaped, multi-color logo, which dedicated itself to this… I wonder where they went?)
