Handheld devices for monitoring blood viscosity typically use reactant-coated electrodes to induce and detect chemical reactions in blood samples. Recently, though, Comsol Multiphysics software from Comsol Inc, Burlington, MA, helped Microvisk develop a handheld unit for home use that employs microelectromechanical sensors (MEMS) on a disposable strip which contains a small cantilever to measure viscosity. The discreetly sized monitor checks blood viscosity in a one-stage process based on physics rather than chemistry. The multiphysics software helped speed this process because it complemented the design flow and real-life testing with simulation. The software can simulate complex designs because it lets users analyze combined mechanics and statics of beams systems, thermal and electric properties of structural materials, and currents being applied to MEMS structures immersed in and interacting with fluids.
