More Information
Summary:This present disclosure relates to sensors capable of sensing mass, stiffness, and chemical or biological substances. More specifically, this disclosure provides the design and implementation of a piecewise-linear resonator realized via diode- and integrated circuit-based feedback electronics and a quartz crystal resonator. The proposed system is fabricated and characterized, and the creation and selective placement of the bifurcation points of the overall electromechanical system is demonstrated by tuning the circuit gains. The demonstrated circuit operates around at least 1 MHz.
