Title: Niccolò Petrini: Innovator in Electro-Acoustic Transducers

Introduction

Niccolò Petrini is a notable inventor based in Florence, Italy. He has made significant contributions to the field of electro-acoustic transducers, holding two patents that showcase his innovative approach to technology.

Latest Patents

Petrini's latest patents focus on a method of operating electro-acoustic transducers, particularly piezoelectric micromachined ultrasonic transducers (PMUTs). This method involves applying an excitation signal to the transducer over a specific interval. After the excitation, a ring-down signal is acquired, which indicates the transducer's behavior post-excitation. The resonance frequency of the transducer is calculated based on this ring-down signal. Additionally, the bias voltage of the transducer can be adjusted according to the resonance frequency. The method also includes transducing an acoustical signal into an electrical reception signal and calculating a damping parameter based on the ring-down signal. This allows for the synthesis of a cross-correlation reference signal, which can enhance the quality of the received signal.
