There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

A special frequency determined by the values of the resistance, capacitance and inductance refers to the resonance in AC circuits. The resonant frequency point occurs where the inductive reactance of ...

The potential to measure mechanical properties through scanning probe microscopy (SPM) has been a huge goal as the field has advanced over the past two decades. Different measurement methods have been ...
