First Claim
Patent Images
1. A cell tester device for an electrochemical cell having a first terminal and a second terminal of opposite polarity in which the cell tester device comprises a translucent plastic layer;
- a transparent electrically conductive electrode printed on the plastic layer and adapted to make electrical contact with the first terminal of the cell;
an ionically conductive electrolyte layer disposed on the transparent electrically conductive electrode and said electrolyte containing at least one electrochromic material that undergoes a visible change in color as the result of a chemical reaction in response to an applied potential voltage; and
a conductive layer disposed over the electrolyte and adapted to make contact with the second terminal of the cell so that when the conductive means of the transparent electrically conductive electrode makes electrical contact with the first terminal of the cell and the conductive layer makes electrical contact with the second terminal of the cell, the electrochromic material will undergo a visible change that can be seen through the transparent electrically conductive electrode.
