摘要： A method of formulating and using pastes, inks or adhesives made of electrically conductive and magnetically polarizable materials bound by a polymeric matrix includes depositing a paste, ink or adhesive at a low temperature, and using the paste, ink or adhesive as an electrically and magnetically and thermally active component, either in a wet or dried state. The polymer matrix provides the deposited product with mechanical properties, which integrate with the electrical and magnetic functions expressed by the other materials in the product. The product can be deposited both on a flexible and a rigid substrate, and can be used directly on the substrate, or in a form released from the substrate. The deposited product may be used as an electromagnetic and thermal component and device, such as an electromagnetic welder, electromagnetic heater, multifunctional material and coating passivating a static electric charge, magnetoresistive sensor, electromechanical relay, or electromechanical actuator.
