Rational Design of Piezoaceelerometers for Measureinents on Compliant Surfaces

RESUMO

The article is dedicated to the problems of developing piezoaccelerometers being the sensors, for measuring the vibroacoustic fields on the surfaces of compliant media. Along with this, presence of the sensor distorts the medium's vibrations near a contact zone. A .criterion, suitable for estimation of the contact sensor's efficiency accounting to its interaction with the object under the measurement, is proposed. On the basis of this criterion the sensitive elements of the piezoaccelerometers having various, configurations are compared. General recommendations on the design of accelerometers for measurements conducted on the soft biotissues of humans have been elaborated.
