Claim:
1. A sensing device, comprising: a substrate; a ferroelectric sensor ink printed onto the substrate to form a first sensor layer; at least one conductive layer formed on the first sensor layer; wherein the at least one conductive layer comprises at least one of: a conductive ink printed onto the first sensor layer to form a first conductive layer, the conductive ink comprising a polymer, Carbon, Ag, Cu and/or metal nanowires; a carbon ink printed on the first conductive layer to form a second conductive layer; and a conductive ink including a silver ink printed on the second conductive layer to form a third conductive layer; wherein the ferroelectric sensor ink comprises a pyro- and piezoelectric polymer, in particular a polymer formed by a copolymer P(VDF-TrFE) or by a relaxor ferroelectric terpolymer P(VDF-TrFE-CFE), and/or wherein the ferroelectric sensor ink is formed by a nanocomposite of inorganic ferroelectric nanoparticles embedded in the pyro- and piezoelectric polymer.
