Several companies in China are now commercializing graphene-based heating elements, embedded in wearable and other devices. Many such devices are now available, shipping globally via retailers such as Amazon and others.

Graphene is an excellent thermal conductor, and using it for heating devices is somewhat surprising. The producers of these devices explain that graphene is strong, thin and flexible, and it provides "pure far infrared radiation" and is also safer and moreenvironmentally friendly compared to other alternatives. Whether this is actually so is an open question.
