MEMS-based Active Control of Macro-Scale Objects

Return to project overview


Operation of PCB/mEMS valve arrays

 
Closing sequence
Loop time: 1 ms
Opening sequence
Loop time: 8 ms
 
Fabrication Process: Laser-based patterning of thin-film; gel-pak transfer; lamination
Opening time:     < 2 ms for flow initiation;
                           8 ms to reach mechanical equilibriumS (max flap deflection)
Closing time:      < 0.9 ms to achieve complete seal from fully opened state
 

Operation of Active Structural Stabilization Experiment
 
Active stabilization of the first mode of column buckling
provides a factor of 2.9x increase in load-bearing capability
