Ultrasonic Transducers Shaped in Archimedean and Fibonacci Spiral: A Comparison
We developed and investigated a particular geometry of transducers, emulating the shape of bats’ cochlea, to transmit and receive ultrasounds in the air. Their design involved the use of polyvinylidene fluoride (PVDF) as a piezoelectric material, thanks to its excellent conformability and flexibilit...
