| The paper deals with problems of designing of piezoaccelerometers that are the primary sensors for measuring of vibroacoustic fields on compliant surfaces. Presence of the sensor effects the vibration of the medium near the contact zone. The criterion is offered that is suitable for estimating of contact sensor's efficiency with the allowance of its interaction with the test object. On this basis, the sensitive elements having different configurations have been compared. General recommendations have been put forward for designing of accelerometers for signal recording from the surfaces of human soft biological tissues. |
