The document summarizes research on modeling the resonant frequency of MEMS relays and switches. It describes a simple mass-spring model used to simulate the resonant switch and analyze the cantilever system's behavior at different driving frequencies. When the frequency matches resonance, the displacement amplitude grows continuously until contact is hit, at which point the oscillation becomes nonlinear. Next steps include revising the model to account for energy loss and other vibration modes, preventing phase shifts on contact, converting it to a physical contact model, and testing prototype devices.
