Piezoelectric Transducer for Mechanical Assessment of Soft Tissues

The innovation of the propossed solution lies in the integration of the dynamic indentation method by using a unimorph piezoelectric transducer as an indentation device. This allows the use of a number of favorable electromechanical properties of piezoelectric transducers, i.e. high sensitivity, generation of vibrations in a wide frequency range, control of the measurement conditions by changing the work mode of the transducer, description of the measurement system by the electromechanical impedance methods. Piezoelectric transducers, due to their properties, are likely to replace many of the current solutions for the measurement of mechanical quantities characterizing soft tissues.
