At present, there are some research institutions using polymer materials to fabricate CMUT and have made some progress.
Polymer materials have the characters of good elasticity, not easy to break and large dynamic range etc..
SU-8 has a smaller reflection coefficient than that of other materials, and the acceptance rate is much higher, so it is an ideal material for capacitive acoustic transducers.
