We investigated this idea by simulating a soft piezoelectric phononic crystal in two dimensions. We explored the modeling of a piezoelectric material undergoing large, nonlinear deformations in a quasi-two-dimensional system. The simulations examined the use of electric fields to generate basic device structures such as resonators and waveguides as well as the phononic behavior of those structures. We also explored combining these structures to form simple devices that can be created, altered, or removed as desired with the applied electric field.
