The present disclosure is directed to a heating mechanism including stretchable heating tape and a rechargeable electrical power source. The stretchable heating tape can be worn to provide heat and pressure relief on different parts of a user's body anisotropically. On one side of such stretchable tape lies a single-layer fabric in which non-stretchable heating wire is at least partially weaved with knitted stretchable yams to make a stretchable fabric that can stretch up to 100%. On the other side of the stretchable tape lies an adhesive material that provides tension at various levels of stretch up to 100% and can sustain multiple hours on direct skin applications. Such stretchable fabric can have a connector coming from one end or both ends which provides a path for power through an inter-connecting cable between the stretchable tape and a controller which includes the power source and its control circuitry.
