Design of Microassembly through Process Modeling in Virtual Reality

Das A.N., Stephanou H.E., University of Texas at Arlington, US

In this work we discuss how construction of microsystems via microassembly can be optimized through simulation of the entire process in virtual reality prior to actual execution. We exercise a holistic approach towards microscale manufacturing [...]

Array-Nozzle EHD Print Head and its Drop-on-Demand Experimentation

Son S., Lee S., Lee W.H., Kim Y.J., An K., Choi J., Sin J., Lee S., Lee W.H., Wijesundara M., Stephanou H.E., Sungkyunkwan University, KR

EHD (electrohydrodynamics) printing has recently attracted attention for micro/nano size pattern devices due to it can make very small droplet than nozzle diameter and possibility of the use of various ink such as including metal, [...]

Dynamic Modeling and Input Shaping for MEMS

Popa D.O., Wen J.T., Stephanou H.E., Skidmore G., Ellis M., Rensselaer Polytechnic Institute, US

In this paper we show that the dynamic performance of MEMS devices can be significantly enhanced using reduced-order modeling techniques and open-loop control via input shaping. Specifically, we apply this methodology to a variety of [...]

In-Plane Micropump: Design Optimization

Sin J., Lee W.H., Stephanou H.E., RPI, US

This paper presents the fabrication, analysis and optimization of a novel monolithically fabricated diaphragm micropump, referred to as an in-plane micropump. Compared to previous technology, the micropump in this paper is fabricated to have all [...]
