Design and Basic Consideration of Electromagnetic Heating Yarns with Foucault Currents for Smart Functional Fabrics

The area of smart and functional materials, in particular fabrics with electric heating, attracts the attention of researchers. The energy harvesters that convert ambient motion to electricity have greatly developed recently. The paper suggests an eddy current microscale mechanism for direct conversion from ambient motion to heat. The proposed mechanism can be used within fabrics for heating and drying moisture. The principles of eddy current heating and possible design of yarns are described. A fundamental estimation of available thermal energy has been obtained from the general basic consideration.
