Abstract: | We present the dynamic loading analysis of a normally closed, remotely actuated, secure coded, electrostatically driven, active microvalve using passive components. The design employs a synergetic approach to incorporates the advantages of both electroacoustic correlation and electrostatic actuation into the microvalve structure. This is carried out by utilising the complex signal processing capabilities of two identical, 5×2-bit Barker sequence encoded, acoustic wave correlators. An electrostatically driven microchannel, comprising of two conducting diaphragms as the top and bottom walls, is placed in between the compressor IDT's of the two correlators. Secure interrogability of the microvalve is demonstrated by the 3-D finite element modelling of the complete structure and the quantitative deduction of the harmonic code dependent microchannel actuation. Furthermore, the dynamic transient analysis is employed to investigation the nonlinear time response of the microvalve and other performance criteria of the structure such as microchannel opening dynamics and the microvalve loading time. © 2009 Springer-Verlag Berlin Heidelberg. |
