Charge your Cellphone by dancing
What do you do if you’re stuck in a field at a pop festival but there’s trouble ahead because your cellphone’s battery is about to run out? Thanks to Dance Charge, it is enough to charge your cellphone.
A generator capable of converting mechanical to electrical energy and after several weeks of head scratching GotWind achieved a generating efficiency of 85% and a generator (Dance charge) small enough in size to be mounted on an armband.
The electrical energy generated is rectified from a bipolar current impulse (AC) to direct current (DC) to charge a rechargeable battery. A high efficiency booster circuit is then used to achieve the constant current power supply to charge a mobile phone, or any other portable electronic device for that matter.
The armband was manufactured from Neoprene with Velcro fixing straps.
The core design principles of generator could also be adopted for generating charge whilst performing other activities such as jogging, or even walking and be leg or waist mounted. GotWind currently researching into other varioations of the product and gaining higher charge efficiencies.
