Paper Abstract

A new actuation mechanism utilizing piezoelectric properties of boron-nitride nanotube (BNNT) for microcantilever beams is proposed here and modeled using a multiple-scale, multi-physic approach. Using the developed model, specific attention is placed on thermal effects on the microbeams made of aluminum and titanium and the results are compared with each other. Different studies are conducted on the microbeams response characteristics such as frequency response, resonance frequency and heat transition effects while the microbeam tip temperature varies. It is found that Titanium microbeam possesses smaller peak frequency response that occurs at lower frequency. Also, it is demonstrated that increasing the temperature will lower resonance frequency in both beams. Finally, the temperature gradient through the beams with respect to time is studied and it is found that Titanium beam can be stabilized in a longer time period.
