Here we present a microcantilever system with a combination of robust Lorentz force-based electromagnetic actuation and highly sensitive optical beam deflection (OBD) method. We present the microcantilevers’ architecture, manufacturing process, and wide characteristics including spring constants, static and dynamic response and a study of coupling between them. Highest measured static electromagnetic and thermal actuation responsivities are 1.82nm/μAT and 1.47×10 -4 nm/μA 2 (or 1.34nm/μW), respectively, while force resolution is 12pN for a 35mN/m microcantilever. During investigations of the Brownian noise of the microcantilevers we have observed anomalous frequency shift caused by static bending. We suggest using this phenomenon to tune micromechanical devices. We propose numerous applications for presented system.
