Lumped Modeling of Thermal Inkjet Print Head

Lee Y-S, Kim M.S., Shin S., Shin S.J., Shin S., Shin S.J., CSE Center, Samsung Advanced Institute of Technology, KR

A lumped model is developed to improve the design of a thermally driven monolithic inkjet print head. The model is based on a two-dimensional heat conduction equation, an empirical pressure-temperature relation and a hydraulic flow-pressure [...]

Static Equivalent Circuit Model for a Capacitive MEMS RF Switch

Tinttunen T., Veijola T., Nieminen H., Ermolov V., Ryhanen T., Helsinki University of Technology, FI

A simulation model for static analysis of a doubly supported capacitive MEMS RF switch has been constructed using electrical equivalencies. Energy-conserving large-displacement macro models for beam deflection, gap capacitance, electrostatic force, and mechanical contact are [...]

Electromechanical Analysis of Micromechanical SOI-Fabricated RF Resonators

Lamminmäki T., Ruokonen K., Tittonen I., Mattila T., Jaakkola O., Oja A., Seppä H., Seppälä P., Seppälä P., Kiihamäki J., Helsinki University of Technology, FI

In this paper, finite element method (FEM) simulations are used to model mechanical properties of MEMS resonators. Using a static displacement analysis the effective spring constant and mass are calculated. Non-linearity of the mechanical restoring [...]

Modeling a Piezoelectric Actuator Using a Transformer Equivalent Circuit

Oms-Elisabelar F., Bergaud C., Nicu L., Martinez A., CNRS, FR

In this paper, we describe both the static and dynamic behaviors of an AFM-like piezoelectric actuator using a transformer equivalent circuit in which both the electrical and mechanical portions are represented by electrical equivalencies. The [...]

Numerical and Analytical Modeling of the Piezoelectric Transformer and Experimental Verification

Hallaert S., Sarraute E., Le Pioufle B., URA CNRS 1375, FR

In this paper, to approach the modeling aspect, we have selected a Rosen-type structure of piezo-electric transformer which, for us, seems very interesting from an educational point of view. Two approaches will be presented, (i) [...]
