Noise in piezoelectric sensors
The Journal of the Acoustical Society of America, 1990Piezoelectric sensor noise generation mechanisms will be reviewed. The sensor needs to be considered as part of a sensor-preamplifier system whose output signal-to-noise is to be maximized. When the preamplifier noise is dominant (as is often the case), an appropriate figure-of-merit for the piezoelectric sensor material is the gd product, where g and ...

A broadly tuned self resonant knock sensor includes a piezoelectric element mounted on a central mounting stud. The element includes a generally annular vibratable portion having a variable radial dimension so as to exhibit resonant vibrations at a plurality of relatively closely spaced resonant frequencies essentially spanning an engine determined ...

Vibrating piezoelectric sensors
Sensors and Actuators A: Physical, 1994Abstract This paper presents the original results obtained in the development of the vibrating piezoelectric sensors loaded with any medium, either solid, liquid or gas. The common feature of such a loading is its ability to vibrate synchronously with the piezoelectric resonator as a compound resonator. The paper introduces a new concept in vibrating

Piezoelectric Sensor Terminology
2002The field of measuring — like all types of technical activities — calls for well and clearly defined terms. Only if specifications are given in an universally understandable way, leaving no ambiguities whatsoever about their meanings and implications can misunderstandings and misinterpretations be avoided.

Background of Piezoelectric Sensors
2002Piezoelectricity is understood as a linear electromechanical interaction between the mechanical and the electrical state in crystals without a center of symmetry. The direct piezoelectric effect is present when a mechanical deformation of the piezoelectric material produces a proportional change in the electric polarization of that material, i.e ...
