A charge amplifier or a voltage amplifier can be used as a signal conditioning circuit
between a piezoelectric element and a meter or a data acquisition board. The outputs of the …

Acoustic signals were measured by the microphones arrays called acoustic camera.
Measurements by acoustic camera allow localization of sound source and by that separate …

In the present paper a new model of piezoresistive accelerometer is proposed in order to
enhance its operation performances. The main task of this accelerometer is to measure …

Piezoelectric elements (PEMs) are used in a variety of applications. In this paper, we
developed a full analytical model and a simple system identification (SI) method of a …

Non-destructive measurements of an electromechanical impedance allow for the effective
assessment of the state of mechanical structures. Piezoelectric transducers, which are …

ABSTRACT A new methodology for damage identification and continuous health monitoring
of a mechanical structure by using piezoelectric sensors and actuators, is proposed in this …

This paper is devoted to modeling the dynamic response of an electromechanical system
consisting of a piezoelectric transducer glued on part of the upper surface of a metallic …

Variations in electric impedance curves of piezoeletric transducers occur under influence of
mechanical load, temperature, electric excitation, among others. Electronic circuits for …

In the chain from sensing to information extraction, there are many traps where errors can
occur, which might lead to false alarms and therefore leave us with the impression of an …
