We present a low power (0.66-51.31mW) electrochemical micropump capable of accurate delivery of a diverse assortment of liquid drug formulations within a wide dynamic range of flow rates (0.33 141.9μL/min) suitable for chronic pain management applications. This system rapidly responds to changes in regimen (<1sec) for on-demand control and has an electrochemically based dose tracking system tha...

In this paper we present the world’s first micropump entirely fabricated using a 3D direct manufacture process based on microstereolithography. The device employs a single pneumatically actuated membrane, with flow rectification provided by a nozzle/diffuser arrangement. A maximum flow rate of just over 2,000 μl/min was achieved with a pneumatic pressure of 2 PSIG and a stroke rate of 96 Hz. Th...

The drive mode of fluid body in microchannel is a key in microfluidic control system. ElectroOsmotic MicroPump (EOP) is a microfluidic system which is controlled by electric field with no moving parts. EOPs are attracting increasing attention due to the ease of fluid control in complex microchannels. The theory of forming Electro-Osmotic-Flow (EOF) is analyzed and governing equations are given ...

A self-powered polymeric micropump based on boronate chemistry is described. The pump is triggered by the presence of glucose in ambient conditions and induces convective fluid flows, with pumping velocity proportional to the glucose concentration. The pumping is due to buoyancy convection that originates from reaction-associated heat flux, as verified from experiments and finite difference mod...

In this paper, the results of modeling and simulation a microcolumn are presented. The is part developed miniature MEMS electron microscope equipped with high-vacuum micropump. Such an arrangement makes device first stand-alone electron-optical to operate without external chamber. Before such can be fabricated, research on particular elements must carried out determine working principles device...
