Surface-micromachined microfluidic devices
Paul C. Galambos,Murat Okandan,Stephen Montague,James H. Smith,Phillip H. Paul,Thomas W. Krygowski,James J. Allen,Christopher A. Nichols,II Jerome F. Jakubczak +8 more
TL;DR: In this article, surface-micromachining-based microfluidic devices are disclosed which can be manufactured using surface micromachines and utilize an electroosmotic force or an electromagnetic field to generate a flow of a fluid in a microchannel that is lined with silicon nitride.
Proceedings ArticleDOI
A New Class of High Force, Low-Voltage, Compliant Actuation System
M. Steven Rodgers,Sridhar Kota,Joel A. Hetrick,Zhe Li,Brian D. Jensen,Thomas W. Krygowski,Samuel L. Miller,Stephen Matthew Barnes,Michael S. Burg +8 more
TL;DR: In this article, the authors presented low-voltage electrostatic actuators that offer a dramatic increase in force over conventional comb drive designs, and these actuators consume only a small fraction of the chip area previously used.
Patent
Surface—micromachined rotatable member having a low-contact-area hub
TL;DR: In this paper, a surface-micromachined rotatable member formed on a substrate and a method for manufacturing thereof is described, which can be a gear or a rotary stage, has a central hub, and an annulus connected to the central hub by an overarching bridge.
Patent
Process for fabricating a microelectromechanical structure
Jeffry J. Sniegowski,Thomas W. Krygowski,Seethambal S. Mani,Scott D. Habermehl,Dale L. Hetherington,James E. Stevens,Paul J. Resnick,Steven R. Volk +7 more
TL;DR: In this article, a process for forming a microelectromechanical (MEM) structure on a substrate having from 5 to 6 or more layers of deposited and patterned polysilicon is described.
Proceedings ArticleDOI
A low-voltage rotary actuator fabricated using a five-level polysilicon surface micromachining technology
TL;DR: In this paper, the design, fabrication and characterization of a low-voltage rotary stepper motor with a lowfriction hub was presented, with an estimated resistive torque of about 6 pN-m.
