The microfabricated sensor is constructed using silicon carbide as the substrate and aluminum nitride (AlN) as the piezoelectric film. The piezoelectric coefficient (d33) of AlN is measured using ...
The knock sensor is made up of a piezoelectric element. A working principle for piezoelectric elements involves the transmission of an electrical current in response to detecting a change in pressure ...
The three core processing techniques implemented are event-driven threshold control (EDTC), vibration event noise (VEN) filtering, and adaptive frame-rate control (AFRC). Using the multi-event-based ...
