Heat generating knee pad

    The heating knee pad will store the energy generated during exercise and release it as heat to help soothe muscles once the workout is complete.
    Made of 'electro-thermal isolation yarn', the concept device will absorb the heat generated by the body during exercise. A coil and magnet electricity generator will store the heat, and then release it into the pad after the workout-creating a soothing warmth. The knee pad's energy storing feature can be switched off or on, and the built-in rechargeable lithium battery will store the energy generated by the coil to produce heat at a later time.
