Disclosed are devices, materials, systems, and methods, including a device that includes one or more structural components, at least one of the one or more structural components comprising substantially HfO2—TiO2 material. Also disclosed is a hemispherical resonator that includes a hemisphere including one or more structural components with at least one of the one or more structural components comprising substantially HfO2—TiO2 material, a forcer electrode configured to apply an electrical force on the hemisphere to cause the hemisphere to oscillate, and one or more sensor electrodes disposed in proximity to the hemisphere and configured to sense an orientation of a vibration pattern of the hemispherical resonator gyroscope.
