A method of generating an enhanced receive signal from a piezoelectric ultrasound transducer is described. The method comprises providing a piezoelectric ultrasound transducer comprising a piezoelectric element operable in flexural mode, receiving a acoustic signal by the piezoelectric element, applying a DC bias to the piezoelectric element prior to receiving the acoustic signal and/or concurrently with receiving the acoustic signal, and generating an enhanced receive signal from the piezoelectric element as a result of receiving the acoustic signal by the piezoelectric element. pMUT-based imaging probes using the above method are also described.
