Microsonic Systems new patented Lateral Ultrasonic Thrust™ (LUT™) technology works by using a Micro-Electrical-Mechanical Systems (MEMS) based transducer, which when excited with RF power generates ultrasonic waves. Since these waves have a very high level of lateral ultrasonic thrust, the coupling of them into a well causes a lateral mixing vortex. This lateral mixing vortex enables the user to rapidly and controllably mix their samples within a well.
Additionally, the intensity of the motion created by our LUT technology is highly controllable. Therefore, lower power settings can be used for the gentle mixing required when dealing with cell based assays, and higher power can be utilized when increased velocity is needed for solubilization.

The Vestibular Dynamic Inclinometer (VDI) is a sensor motivated bu the human vesitbular system that is made up of two MEMS linear accelerometers and one MEMS gyroscope.

The VDI measures dynamic inclination parameters – inclination, angular velocity, angular acceleration and magnitude of acceleration of the base/surface of contact (gravity).

Topology optimization of fluids with the lattice Boltzmann method

admin — Wed, 19 Oct 2011 16:22:09 +0000

Topology Optimization using a GCMMA optimization algorithm and the lattice Boltzmann method to find the optimal material layout for a micro-mixer. Two miscible (Red and blue) fluids enter a channel and should be mixed at the outlet. The evolution of the channel design is displayed on top with green being solid material and white being fluid. The streamlines are overlayed for convenience. The bottom plot shows the mixing profile of the design.
