Title: Texture-inducible substrate

Abstract

A texture-inducible substrate includes a backplate, a deformable membrane positioned in front of the backplate to form a gap therebetween, and a ferrofluid contained in the gap. The substrate also includes an electromagnet positioned on the backplate to induce, when activated, a local volume of the ferrofluid to expand in volume and increase in viscosity so as to locally deform and raise an adjacent section of the deformable membrane.
