Designing MEMS Gyroscopes for Manufacturing

Manufacturing variations are of critical importance in MEMS design. In this MEMS gyroscope case study, Veryst created an approach to look at the effect of a range of manufacturing variations on MEMS devices using the same mesh. We also use semi-analytic equations to enable scalable modeling of the gyroscope electrostatic actuation and pick-off (which senses the motion produced by rotation).

How a Pop-Up Rubber Toy Jumps – Analysis and Simulation

Pop-up rubber jumpers are fun toys that unexpectedly jump and pop when placed on a flat surface after they are inverted. The poppers are hemispherical rubber domes which can be easily inverted inside-out, a process that stores elastic energy in the rubber material. This case study showcases how simulation can effectively be used to unravel complex nonlinear phenomena such as the inversion and jump of a popper toy.

Modeling of Piezoelectrically Enhanced Soft Artificial Muscles

Piezoelectric soft artificial muscles provide actuation in robotics, medical devices, and wearable technologies. Their high power-to-weight ratios make them ideally suited for such applications. However, the coupled nonlinear relationship between their geometry, material response, and performance poses a challenge for their design. Simulating the performance of artificial muscle devices enables rapid concept testing, design iteration, and material selection.

Simulation Verification of PLLA Stent Implantation

Regulatory agencies such as the US Food and Drug Administration (FDA) require medical device manufacturers to follow rigorous simulation verification procedures to assess credibility of numerical simulations used to support submissions. In this case study, we simulate crimping of a Poly L-lactic Acid (PLLA) stent in the implantation process and demonstrate numerical solution verification.

Failure Analysis

The consultants at Veryst provide failure and root cause analyses using core engineering disciplines to evaluate different failure scenarios.  Engineering specialties we apply to failure analyses include: mechanical engineering, materials science (metallurgy, ceramics, polymer science, compo
