Patent ID: 8414962

Claim:
A method of forming a microcontact printed layer of Ba(Ti 1-x M x )O 3 where M is a dopant thereof on to a Ni foil substrate comprising, applying a Ba(Ti 1-x M x )O 3 precursor solution where 0.005≦x≦0.02 where M is any of Mn, Y, Ho, Dy, Er, Mg, Ca, Co or mixtures thereof onto a stamp that has a predetermined pattern thereon to form a coated stamp, compressing the coated stamp onto a Ni foil substrate to form a pattern of the Ba(Ti 1-x M x )O 3 precursor solution on the Ni foil substrate, drying the pattern, pyrolyzing the pattern and firing the pattern to produce a micro contact printed layer of Ba(Ti 1-x M x )O 3 on the Ni foil substrate.
