Mode characteristics and frequency responses of cantilever (clamped-free) type suspended microchannel resonators (SMRs) with a traveling particle. a Schematic of a cantilever-type SMR with its top cover removed. b Mode shape and associated mass responsivity of the resonance frequency of the first and second flexural bending modes. c Variation of the first and second mode resonance frequencies while a particle travels through the integrated channel
