A stretchable piezoelectric thin film, and method of manufacture, an open mesh structure formed by a repeating branching and joining pattern. The thin film is manufactured by slowly lifting amino acid nanofibrils from a water-alcohol biphasic solvent. The film automatically assembles into a truss-like mesh network of amino acid nanofibrils that allows the open meshes to close with narrowed intersection angles between the amino acid nanofibrils. The alcohol molecules of the water-alcohol biphasic solvent preferably bind to the carboxyl groups on the amino acid surfaces thus limiting the growth along the side facets of the amino acid surfaces and promoting growth along the growth front producing a bifurcation in the amino acid biocrystal network.
