Abstract

This paper presents a sensitive, broad-bandwidth MEMS ultrasound transducer based on frequency interleaving of resonant transducers. Cantilever-like diaphragm transducers with piezoelectric ZnO films have been connected in parallel, so that the sensitivity as a receiver and the sound output as a transmitter are measured to be about 30 times larger than those of a single transducer. The interleaving of the transducers not only increases the sensitivity but also broadens the useable bandwidth greatly.
