Using Topology Derived Masks to Facilitate 3D Design

Schiek R., Schmidt R., Sandia National Laboratories, US

To accelerate MEMS design for surface micromachining applications, an algorithm and associated design tool have been created which translates designers’ 3D models into 2D lithographic production masks. Typically, designing a surface micromachined, MEMS device requires [...]

A New, Topology Driven Method for Automatic Mask Generation from Three-Dimensional Models

Schiek R., Schmidt R., Sandia National Laboratories, US

We have developed an algorithm which when given a three-dimensional object can infer from the objects topology the two-dimensional masks needed to produce that object with surface micromachining.Our algorithm, called Faethm, calculates the required two-dimensional [...]

Topology Trade-offs in the Synthesis of Chip-based Electrophoretic Separation Systems

Pfeiffer A.J., Mukherjee T., Hauan S., Carnegie Mellon University, US

Micro-scale electrophoretic separation systems provide a highly effective, versatile and inexpensive method for separating a wide variety of chemical components. Particularly useful applications include separation of biological molecules, chemical sensing, and mobile drub delivery systems. [...]

Insects Separate Diffusing Particles in Parallel

Lawry J.V., California Academy of Sciences, US

The circulation of insects and other invertebrates transfers heat, mass, and momentum within micro-fluids through phase interfaces of complex geometry at size ranges important for developing compact energy and chemical systems. Pump size and vascular [...]
