Nano robotic manipulation is mainly influenced by the performance of manipulation tools. Micro and nano grippers offer a promising method of grabbing and manipulating objects on a micro and nanoscale in three dimensions. Researchers have increasingly turned to boron nitride Nanotubes for applications due to their unique physicochemical properties, such as hydrophobicity, heat and electrical insulation, resistance to oxidation, and ability to store hydrogen. Hence an endeavor is made to use boron nitride nanotubes (BNNTs) at the tip of a microgripper with a Piezoelectric (PZT) actuator and a two-stage flexure-based amplification to manipulate nanowires and nanotubes with jaw displacements in the sub-100 nm range. The vibration response analysis of single walled boron nitride nanotubes is indispensable to achieve precise and well-controlled motion of the end effector. A free vibration analysis of Single walled boron nitride nanotubes (SWBNNT) based on Euler-Bernoulli beam theory is performed and is compared with results from the finite element method. The displacement analysis of piezoelectric driven ceramic plate in micro gripper is carried out in at different driving voltages and the result shown that the displacement increases linearly with the driving voltage. The modal vibration analysis of micro grippers with tip material single walled boron nitride nanotubes (SWBNNT) is performed in FEM software to determine and compare the dominant mode of vibration for grabbing and releasing the nano objects. SWBNNT is considered to be transversely isotropic material and have a cantilevered configuration in micro grippers.
