Background, Motivation and Objective This study builds on previous research to investigate the adaption of a miniaturized class IV transducer configuration, which has a needle end-effector attached, for use in bone biopsy. The transducer has been optimized to maximize needle displacement, with the objective of controlled penetration through bone tissue. Flextensional transducers typically comprise of a transduction material sandwiched between two metal shells. These devices have been utilized in SONAR applications, but more recently a class V configuration has been successfully miniaturized for use in bone cutting procedures. Initial research on the optimization of a miniaturized class IV flextensional transducer has demonstrated that the class IV configuration exhibits a higher level of performance for the same piezoceramic volume in comparison with a miniaturized class V configuration.
