Abstract: Systems and Methods for controlling one or more mechanical resonators and determining information from resonant shift of the resonator(s) behavior, including at least one mechanical resonator, an excitation element for driving the resonator(s), a sensor for monitoring the motion of the resonator(s), at least one phase locked loop (PLL) in feedback between the excitation and monitoring elements, wherein each PLL is configured to operate at or near a different resonant mode of the resonator(s), and a processor for determining information from PLL internal signals indicative of a resonator frequency shift.

Abstract: Serial suspended microchannel resonator sensor array. The array includes a plurality of resonator cantilevers in fluid communication with one another and a plurality of delay channels in fluid communication with, and disposed between, the resonator cantilevers. An object introduced into the array will flow in one direction and be measured by each of the cantilevers in turn after a selected delay in the delay channels.
