A suspended device structure comprises a substrate, a cavity disposed in a surface of the substrate, and a device suspended entirely over a bottom of the cavity. The device is a piezoelectric device and is suspended at least by a tether that physically connects the device to the substrate. The tether has a non-linear centerline. A wafer can comprise a plurality of suspended device structures. A device structure can comprise a device over a sacrificial portion or cavity and a tether with a tether opening extending to the sacrificial portion or cavity. The tether or tether opening can have a T shape. The tether can have a tether length at least one third as large as a device length and the device can have a device length at least twice as large as a device width.
