However, some medical accidents due to the needle structural characteristics will threaten patients’ security and induce pain. To avoid this, this research aimed to develop a piezoelectric vibration-based syringe system for medical applications. Because of the electromechanical interaction of the piezoelectric element, this system possesses the functions of the actuator and the sensor. When it acts as an actuator, the reduction of the insertion force about 36% can be found when adding high frequency vibration to the needle during the insertion. On the other side, by measuring the input electrical impedance of the system, the mechanical impedance of tissues can be detected indirectly. The experimental results demonstrated that this method is able to distinguish various tissues obviously. By minimizing the insertion force and obtaining the tissues information, it is possible to simplify several medical procedures, enhance the surgery success rates, ease patients’ pain and reduce medical risks.
