Abstract: Embodiments provide an ultrasound transducer. The ultrasound transducer may include a multi-layered membrane having a plurality of slits extending through the membrane, thereby forming a plurality of sections of the membrane at least partially separated by the slits. Each slit extends from a perimeter of the membrane to a respective end position at a predetermined distance away from a center of the membrane. The plurality of sections of the membrane are connected to each other at the center of the membrane.
