Neurovascular modeling: small-batch manufacturing of silicone vascular replicas.
BACKGROUND AND PURPOSE Realistic, population based cerebrovascular replicas are required for the development of neuroendovascular devices. The objective of this work was to develop an efficient methodology for manufacturing realistic cerebrovascular replicas. MATERIALS AND METHODS Brain MR angiography data from 20 patients were acquired. The centerline of the vasculature was calculated, and g...
متن کاملDesign, Fabrication, and Testing of Micromachined Silicone Rubber Membrane Valves
Technologies for fabricating silicone rubber membranes and integrating them with other processes on silicon wafers have been developed. Silicone rubber has been found to have exceptional mechanical properties including low modulus, high elongation, and good sealing. Thermopneumatically actuated, normally open, silicone rubber membrane valves with optimized components have been designed, fabrica...
متن کاملCompact Modeling of CMOS Transistors under Uniaxial Stress
Changes in the BSIM3 compact model are necessary in order to accurately simulate the CMOS transistors under applied uniaxial stress. In this paper we focus on the analysis of external uniaxial mechanical stress effects on DC BSIM3 model parameters of bulk MOS-FETs fabricated in a 0.8μm CMOS process. The results show that stress influences mostly the carriers mobility while the threshold voltage...
متن کاملMethod to study cell migration under uniaxial compression
The chemical, physical, and mechanical properties of the extracellular environment have a strong effect on cell migration. Aspects such as pore size or stiffness of the matrix influence the selection of the mechanism used by cells to propel themselves, including by pseudopods or blebbing. How a cell perceives its environment and how such a cue triggers a change in behavior are largely unknown, ...
متن کاملBuckling of Ge nanowires under uniaxial compression
Molecular dynamics simulations are performed to investigate the buckling properties of [100]-, [110]-, [111]-, and [112]-oriented single-crystalline germanium nanowires under uniaxial compression. The effects of simulation temperature, strain rate, and wire length on the buckling behaviour are investigated. The simulation results indicate that critical load clearly decreases with increasing tem...
