Despite of the existing successful clinical applications, however, the interaction, i.e. artificial sensing, between the robot and the patient is still very limited. With the help of various cameras, vision is almost the only feeling that a robot can have. In order to imitate the human skin, various signals e.g., the strength of pressure, change of strength, speed and acceleration should be measured by the robot. Here we explore some design and fabrication techniques using different piezoelectric materials (CdS,AlN,ZnO) on an effective sensor which will be installed on surgical robotic arm in the future. In this model, we investigate the Quality factor, Power dissipation & displacement with respect to Eigen frequency.
