Abstract

A method of manufacturing an electrical device comprises the steps of providing a substrate, providing an electrical component on the substrate, providing a first electrical contact on the substrate that is electrically connected to the electrical component, and providing an electrochemical cell on or integrating the substrate for providing electrical energy to said electrical component. The electrochemical cell comprises at least one electrochemical layer comprising a cured or dried ink and a first electrode contact electrically connected to said at least one electrochemical layer. The method further includes the step of securing the electrochemical cell to the substrate through an electrically conductive connection that provides both a structural connection and an electrical connection between the first electrical contact and the first electrode contact.
