Liquid Proof-mass Accelerometer
Equilibrium Analysis Suppose at equilibrium state: From the classical ideal gas law:
Fluid in sealed channel Spring-mass system Comparisons with Spring-Mass System 4 th order 2 nd order conditionally 2 nd order
Feasibility Significant response High flow rate Big m Small k Large size Presumption: Overall size: 10mm by 10mm by 2mm Damping medium: air Moving liquid: DI water Future work to prove feasibility: Calculate the maximum liquid displacement may achieve Estimate the maximum flow rate, and compare to previous values in the CNT flow sensor project
