A Comparative Study of Two Types of Bifurcation-Based MEMS Sensors
摘要
This paper compares two types of inertial electrostatic MEMS methane sensors, one based on a cyclic-fold bifurcation and another based on a primary Hopf bifurcation. We find the Hopf-based sensor is 40% more sensitive than the cyclic-fold sensor and that the detection signal, and therefore the signal-to-noise ratio, of the former is 25% larger than that of the latter.
