Head skis using vibration energy harvesting for a better edge grip

Posted By: Zeke Piestrup on October 7, 2009 5:15 pm

It’s about as green as energy can get.  It’s called vibration energy harvesting (VEH) and its principles are being used in Head skis.  Vibrations in the skis generate voltage, called the piezo effect.  The voltage is captured and then sent back through the fiber composite in the ski to dampen the vibrations.

Jerry Ruddle, executive vice president and general manager of Advanced Ceramics explained in an article for Product Design & Devolpment that “an increase in the width of today’s skis has caused higher torsional forces, which creates twisting in the skis, decreasing the controllable edge. AVC helps to quiet the torsional forces with the dampening effect, recycling the energy back to the structure to produce the perfect edge grip.

Crazy, awesome science in action.
