  • Publication number: 20220150625
    Abstract: An electro-acoustical transducer such as a Piezoelectric Micromachined Ultrasonic Transducers is coupled with an adjustable load circuit having a set of adjustable load parameters including resistance and inductance parameters. Starting from at least one resonance frequency or at least one ring-down parameter of the electro-acoustical transducer a set of model parameters is calculated for a Butterworth-Van Dyke (BVD) model of the electro-acoustical transducer. The BVD model includes an equivalent circuit network having a constant capacitance coupled to a RLC branch and the adjustable load circuit is coupled with the electro-acoustical transducer at an input port of the equivalent circuit network of the model of the electro-acoustical transducer. The adjustable load parameters are adjusted as a function of the set of model parameters calculated for the BVD model of the electro-acoustic transducer to increase the bandwidth or the sensitivity of the electro-acoustic transducer.

  • Publication number: 20220128674
    Abstract: A method of operating electro-acoustical transducers such as PMUTs involves applying to the transducer an excitation signal over an excitation interval, acquiring at the transducer a ring-down signal indicative of the ring-down behavior of the transducer after the end of the excitation interval, and calculating, as a function of said ring-down signal, a resonance frequency of the electro-acoustical transducer. A bias voltage of the electro-acoustical transducer can be controlled as a function of the resonance frequency. An acoustical signal received can be transduced into an electrical reception signal and a damping parameter of the electro-acoustical transducer can be calculated as a function of the ring-down signal so that a cross-correlation reference signal can be synthesized as a function of the resonance frequency and the damping ratio of the electro-acoustical transducer.

  • Publication number: 20200221968
    Abstract: A wearable sensing device includes a connector socket provided with contact pads connectable to sensing electrodes for sensing biological electrical signals. A supply module is provided with a battery, which is housed in a first casing configured for reversible coupling with the connector socket. A control module is housed in a second casing distinct from the first casing and configured for coupling with the supply module and with the connector socket. The control module is equipped with a processing unit configured to process biological electrical signals detectable through the contact pads. Mechanical-connection members couple the supply module to the connector socket. Electrical-connection members distinct from the mechanical-connection members are configured to connect the battery and the contact pads to the control module.
