Modular Architecture of a Non-Contact Pinch Actuation Micropump

Modular Architecture of a Non-Contact Pinch Actuation Micropump

This paper demonstrates a modular architecture of a non-contact actuation micropump setup. Rapid hot embossing prototyping was employed in micropump fabrication by using printed circuit board (PCB) as a mold material in polymer casting. Actuator-membrane gap separation was studied, with experimental investigation of three separation distances: 2.0 mm, 2.5 mm and 3.5 mm. To enhance the micropump...

Glass valveless micropump using electromagnetic actuation

We present a valveless micropump in glass, which is magnetically actuated using the sinusoidal current of an external electromagnet. We employ a powder blasting microerosion process for microstructuring the glass substrates and fusion bonding for assembly of the multi-layered microfluidic chip. The reciprocating type micropump contains two nozzle/diffuser elements and a poly(dimethylsiloxane) m...

Study of Volumetric Flow Rate of a Micropump Using a Non-classical Elasticity Theory

The purpose of this research is to study the mechanical behavior of a micropump with clamped circular diaphragm which is the main component of drug delivery systems. In this paper, the non-linear governing equations of the circular microplate using Kirchhoff thin plate theory was been extracted based on the modified couple stress (MCST) and classical (CT) theories. Then, the non-linear equation...

Modular Actuation Systems: A Scalable Solution for Delivering Robotic Performance

Extremely resilient actuators can built by collecting force-generating, computational, and sensing modules together to fit into the allotted volume. Including extra modules makes the actuator damage tolerant. This modular architecture allows an actuator at any performance point to be easily synthesized from a small number of component parts. The embedded intelligence, sensing and inter-module c...
