Latest Patents

One of his latest patents is the "Modular stacked variable-compression micropump and method of making same." This invention features a micropump assembly comprised of modular stacked pump stages, which are preferably arranged vertically. The design allows each pumping chamber to be compressed by two pumping membranes, providing twice the compression compared to conventional planar pump designs. Additionally, this stacked design eliminates the need for bidirectional movement of the pumping membrane, and the number of stacked pumping stages can be adjusted post-fabrication to meet specific pressure requirements.

Another significant patent is the "Micropump assembly for a microgas chromatograph and the like." This MEMS-fabricated microvacuum pump assembly is designed to operate in air and can be easily integrated into MEMS-fabricated microfluidic systems. The assembly includes a series of pumping cavities with electrostatically-actuated membranes interconnected by microvalves. The innovative design features a large deflection electrostatic actuator with a curved fixed drive electrode, allowing for greater travel distances of the movable electrode with lower voltage requirements.
