The current invention discloses a treatment device having a heat source, a power source, a heat applicator and a lighting mechanism. The power source includes at least one nanotech battery, ensuring superior properties such as prolonged electricity production and prompt recharging. The heat applicator includes a heat conductive layer made from nanofibers, providing highly efficient heat distribution to the targeted regions. The lighting mechanism employs light emitting nano fibers to treat targeted regions. The power source provides energy to the heat and light source, which generates heat and light so that the applicator may distribute to an injury site or wound bed of a user. The current device may also be used for cooling, instead of heating applications. In addition to the medical utilizations, the current device may also play a central role in other apparatus that require thermal control capabilities.
