Abstract

An ultrasound transducer of a vehicle system includes a support member that attaches to and connects to the bottom portion of a membrane of the ultrasound transducer and supports the membrane, wherein the support member includes one or more cantilevers with a first end attaching to the membrane and a second end attaching to a support portion of the support member that attaches to the substrate, wherein the cantilever extends across and floats above the substrate, wherein the first end of the cantilever includes a stub extending away from a surface of the cantilever, wherein the stub extends away from the surface without contacting the substrate, wherein the one or more cantilevers includes one or more piezoelectric layers on the surface of the cantilever.
