摘要

Cantilever sensitivity under low mass loading is crucial issue for various sensing applications. Recent advancements promise and focus on the development of high performance cantilevers for effective low mass sensing. MEMS cantilevers are commonly used for low level bio-molecular detection due to their most flexible hinging type structure. The micro-cantilever design used for bio-sensing can also be used for RF switching under the actuation potential. For low mass loading rectangular cantilever does not offer better deflection due to its uniform volume. Also in RF switching application these beams take large actuation voltage for switching. This paper study five different micro-cantilever beam designs. Some proposed designs exhibit better deflection for low mass loading. Hence these designs can be used for low level sensing application.
