To build the device, I created four electromagnetic generators, each consisting of a copper coil and a moving magnet inside it. To make each coil, I wrapped copper wire approximately 1, 000 times around a tube, creating a coil capable of generating electrical energy when crossed by the movement of the magnet. The four coils were integrated into the sleeves of a T-shirt, two on each arm, to take advantage of the natural movements of the body during dancing and physical activity. https://drive.google.com/file/d/1lImamN3XoDZmCgDjRbyJP7tDHaXYQlnk/view?usp=drive_link

As the user moves, the magnets slide inside the tubes, passing through the coils and generating electricity through the principle of electromagnetic induction. To connect the different modules, the wires from each coil run along the arms and are integrated into the garment until they reach the back of the shirt.
On the back of the garment, I placed a breadboard containing the electronic circuit and a rechargeable battery, which collect and store the energy produced by the four generators. The electricity generated by the coils is directed to the circuit and then stored in the battery.
This distributed system transforms body movement into electrical energy while remaining fully wearable and integrated into the clothing. The decision to place the generators in the sleeves came from the intention of utilizing one of the most active parts of the body during a musical experience, making energy generation a direct consequence of physical participation.

During the development of the prototype, I carried out several iterations to test the number of coil turns, the dimensions of the components, the positioning of the generators, and the routing of the wires within the garment. Through these tests, I progressively improved the reliability of the system and its integration into the wearable, seeking a balance between technical functionality, comfort, and freedom of movement. The final result is a device that makes the relationship between body movement and energy tangible and visible, transforming the body itself into a source of energy production.
