Patent attributes
A method for manufacturing a piezoelectric element for generating electricity upon flexing of the element including the steps spin-coating a first substrate layer onto a support substrate; depositing a first electrode film onto the first substrate layer; spin coating polyvinylidene fluoride (PVDF) containing solution on the first electrode film to result in a PVDF film; annealing the PVDF film; depositing a second electrode film onto the PVDF film; spin-coating a second substrate layer on top of the second electrode film; forming a hole through the first and second substrate layers; filling the hole with silver paste to contact to the first and second electrode layers; peeling a resulting substrate/electrode/PVDF/electrode/substrate device from the support substrate; and placing a drop of silver paste in the hole formed in the first substrate layer.
