A magnetically actuated ball valve applicable for small-scale fluid flows

Magnetically-actuated artificial cilia for microfluidic propulsion.

In this paper we quantitatively analyse the performance of magnetically-driven artificial cilia for lab-on-a-chip applications. The artificial cilia are fabricated using thin polymer films with embedded magnetic nano-particles and their deformation is studied under different external magnetic fields and flows. A coupled magneto-mechanical solid-fluid model that accurately captures the interacti...

Magnetically Actuated Multiscale Medical Robots

Magnetic manipulation systems designed to date have typically relied on either stationary electromagnetswhich facilitate straightforward real-time control, but result in large and complex systemsor slowly moving permanent magnetswhich generate strong fields, but are typically controlled in a quasistatic fashion. In the Telerobotics Lab at the University of Utah, we are exploring the use of smal...

A Magnetically-Actuated Friction Feedback Mouse

We have designed and built a passive haptic display by integrating an electromagnet into an infra-red optical mouse. When the electromagnet is not energized, the mouse acts normally, with the same low friction and only a slight increase in mass. Energizing the electromagnet attracts the mouse towards a ferromagnetic mouse pad, increasing the normal force, and thus the frictional force, between ...

Towards a Magnetically Actuated Laser Scanner for Endoscopic Microsurgeries

This article presents the design and assembly of a novel magnetically actuated endoscopic laser scanner device. The device is designed to perform 2D position control and high speed scanning of a fiber-based laser for operation in narrow workspaces. The device includes laser focusing optics to allow non-contact incisions and tablet-based control interface for intuitive teleoperation. The perform...
