Introduction

The presented invention allows for generating electricity during the practice of different sports, such as mountaineering, skiing or hiking. The electric current produced by the energy harvester device integrated within the stem of poles can be directly exploited in order to recharge a small battery and therefore power a radio beacon transmitter, which is very often used by rescuers in case of an avalanche.

Technical features

The presented invention relates to a ski or a hiking pole equipped with a radio beacon transmitter that is self-supplied by a magnetic-inductive energy harvester. The proposed device comprises a stem, a handle, a shoe, a fixed magnet and a movable one which is placed inside the sliding guide within the tubular cavity, two symmetrical windings made ​​of copper wire, an electronic card that is needed to rectify the current produced, a capacitor and a battery.

Possible Applications

  • Generating electricity during the practice of different sports, such as mountaineering, skiing or hiking;
  • The electric current produced by the energy harvester device integrated within the stem of poles can be directly exploited in order to recharge a small battery and therefore power a radio beacon transmitter.

Advantages

  • When subjected to vibration, the proposed device exploits the force of gravity and the vertical position of the pole to generate an electric tension inside the windings and therefore recharge a battery;
  • efficacy and input-to-output ratio of higher generation with respect to the remaining solutions which are currently available on the market.
