The Spark Suit is a research project being run by the Nike Sports Research Lab. It is expected to be completed in 2012. The suit is essentially a wearable generator based on nanotechnology.
The concept of the Spark Suit is to convert the movements of the wearer into electricity using nano-ion pumps. This technology has a possible application in a hypothetical vehicle called the Nike ONE.
Due to the extra resistance caused by the electrical generator, the Spark Suit can be used to strategically impede movement. It therefore might allow people to strategically build muscle mass and improve coordination, as well as a weight loss tool.
