A sensing pad includes a first sensing layer, a second sensing layer and a spacer layer. Examples of such peptides include NH2-KWKSFIKKLTTAVKKVLTTGLPALIS-COOH and NH2-KWKSFIKKLTSAAKKVVTTAKPLISS-COOH. The adhesive maintains an intimate, positive contact with both metal surfaces ensuring adequate bonding performance and maximized bonding surface area during a defined heat or bake cycle.
