Abstract

Nano-mechanical sensing exploiting frequency shift of a cantilever beam to obtain the mass of an object is well established. This paper is aimed at investigating the possibility of sensing mass as well as rotary inertia of an attached object. The rotary inertia of an object gives additional insight...
