Advanced Manufacturing of Free Form Optical Sensing Devices Using Predictive Multiscale Modeling of Phase­‐Transforming Materials

We propose to extend our QuasiContinuum/Cascading-Cauchy-Born (QC/CCB) methodology for predictive simulation of phrase transforming materials to handle dynamic loading and non-uniform temperatures effects, and to integrate this new methodology into Third Wave System’s AdvantEdge machining simulation software package.

Fluid Flow on 3D Printed Surfaces

The proposed work will be conducted with parts printed with a Stratasys Dimension 1200es 3D printer, which uses an acrylonitritle butadiene styrene (ABS) thermoplastic building material, or a MakerBot Replicator 2, which uses polylactic acid (PLA). Additional materials and processes will also be available through our collaboration with Stratasys.

Nanomaterial-Based Electrodes for MRI Applications in Deep Brain Stimulation

To overcome current challenge of metallic electrodes used in DBS which create severe image artifacts and brain tissue heating, especially in ultrahigh field MRI systems, we propose to design, fabricate and evaluate new electrodes using two candidate nanomaterials – carbon nanotubes and graphene. The proposed nanomaterials have magnetic susceptibility close to that of brain tissue, cause less eddy currents and allow a variety of cells to attach to their surfaces for desirable DBS implants.
