Abstract: A composite exhibiting a thermoelectric effect is provided. The composite comprises a metal sulphosalt, an electrically conductive polymer, and fibres. A method of making a composite material is also provided, comprising mixing the components. The three components work together to provide a low-cost thermoelectric composite that utilises readily available materials. A friction material and a thermoelectric device comprising the composite of the invention are also discussed. Preferably a copper sulphosalt is used, such as tetrahedrite. Preferably man-made vitreous fibres and a binder are used.
