Pressure driven tough micro pump

Weise F., Klett M., Schober A., Technische Universitat Ilmenau, DE

We have developed pressure driven micro pump. They can deliver gas and liquid. That is an absolute advantage of the scale of this pump. Our pump is designed for integration in a multi well plate [...]

Micro bioreactor for muliwell plates with an active micro fluidic system for 3D cultivation

Weise F., Augspurger C., Klett M., Schober A., Technische Universitat Ilmenau, DE

We have designed a micro system - suitable for parallelization - to culture cells three dimensional. Our system consists of the CellChip, a body and a pneumatically driven micro pump.The aim of our system is [...]

Novel Electro Magnetic Micro Pump

Feldmann M., Demming S., Büttgenbach S., Institute for Microtechnology, DE

The mergence of partial aspects and functional components of micro actuators and micro fluidic technology allows the development of complex micro systems. This enormous potential is shown in this article by the realization of an [...]

Whole Blood Pumped by Laser Driven Micropump

Ussing T., Petersen L.V., Krühne U., Højslet L., FluimediX, DK

A novel laser driven peristaltic micro-pump for the manipulation of fluids in a micro system has been explored and validated on whole blood in saline solution. The pump is based on laser-induced film-boiling of the [...]

Pumping Capacity and Reliability Study on Silicon-Based Cryogenic Micro Pump

Zhao Y., Li B., Ludlow D., Zhang X., Boston University, US

As part of a program to develop a cooling system for satellite instrumentation capable of working at cryogenic temperature, we present herein pumping capacity and material reliability study on a silicon-based cryogenic micro pump which [...]

System Level Analysis for a Locomotive Inspection Robot with Integrated Microsystems

Jeong Y., Kim B., Oh H., Park J-O, Korea Institute of Science & Technology, KR

In this paper, we describe a locomotive inspection robot with integrated microsystems that comprises a micro pump, micro valves, micro channels, a sophisticated pressure amplification system with multi-bellows and biocompatible linear actuators with plastic coated [...]

Numerical Simulation of Pulse-Width-Modulated Micropumps with Diffuser/Nozzle Elements

Nguyen N-T., Huang X., Nanyang Technological University, SG

This paper presents the numerical simulation of a new control method for dynamic micropumps with diffuser/nozzle elements: the pulse-width-modulation (PWM) of the drive signal. A piezo disk with a square wave signal actuates the pump, [...]

Modeling of a Piezo Paddle Mikro Pump

Ederer I., Technical University of Münich, DE

In this paper an analytical method will be presentea to describe the behavior of a piezo electric paddle pump. For that, mechanical and fluidic mechanism are combined in a one mass oscillator model with fluidic [...]
