Abstract
A sensor assembly including one or more capacitive micromachined ultrasonic transducer (CMUT) microarray modules which are provided with a number of individual transducers. The transducers include silicon device and backing layers joined by a fused benzocyclobutene (BCB) layer which defines the transducer air gap, and which are arranged to simulate or orient individual transducers in a hyperbolic paraboloid geometry. The transducers/sensor are arranged in a matrix and are activatable to emit and receive reflected beam signals at a frequency of between about 100 to 170 kHz.
