摘要
This paper presents a monolithic mechanically-bistable mechanism that does not rely on residual stress for its bistability. The bistable mechanism comprises two centrally-clamped parallel beams that have a curved shape but no residual stress after fabrication. Modal analysis and FEA simulation of the beams are used to predict and design the bistable behavior, and they agree well. Micro-scale mechanisms are fabricated by DRIE and their test results agree well with the theoretical and numerical predictions.
