smartdumbbell / dumbbell


Smartdumbbell is a dumb-bell that converts kinetic energy into electricity through exercise.
Inside the dumb-bell is an energy converter and an energy storage. Through the up and down motion, the kinetic energy gets absorbed by the transducer and converted into electrical energy. After storing up some energy, the battery supplies the displays with electricity. The display provides the user with visual feedback during training. It could, for example, count the number of lift-ups or measure the training time.
