We present a combination of transient electro-thermal simulations of three-dimensional interconnect structures and the calculation of their coupled intrinsic thermo-mechanical stress distributions. For the numerical solution of the electro-thermal as well as the thermo-mechanical stress problem, we apply the finite element method. A practical example is presented where the temperature and the p...

As micro-device application in consumer and commercial products develops, efficient tools are required to simulate device dynamics and assess structural performance. An integrated methodology is developed for studying the dynamics of thin film bifurcating structures. Results are presented for a generic thin film structure, which exhibit classical electro-mechanical hysteresis. Such structures c...

Keywords: MHD flow control Nonlinear boundary control Active mixing enhancement Distributed parameter systems a b s t r a c t A nonlinear Lyapunov-based boundary feedback control law is proposed for mixing enhancement in a 2D magnetohydrodynamic (MHD) channel flow, also known as Hartmann flow, which is electrically conducting, incompressible, and subject to an external transverse magnetic field...

The lifetime of micro electro–thermo–mechanical actuators with complex electro–thermo–mechanical coupling mechanisms can be decreased significantly due to unexpected failure events. Even more serious is the fact that various failures are tightly coupled due to micro-size and multi-physics effects. Interrelation between performance and potential failures should be established to predict reliabil...

The electro-mechanical sensing properties of freestanding monolayered membranes of dodecanethiol coated 7 nm gold nanoparticles (NPs) are investigated using AFM force spectroscopy and conductive AFM simultaneously. The electrical resistance of the NP membranes increases sensitively with the point-load force applied in the center of the membranes using an AFM tip. Numerical simulations of electr...
