Abstract: Dip pen nanolithography (DPN) is a flexible nanofabrication process for creating 2-D nanoscale features on a surface using an “inked” tip. Although a variety of ink-surface combinations can be ...

Abstract: A summary of recent research in micropositioning and nanopositioning is presented. The work is classified into five groups by actuation approach, including piezoelectric, magnetic, electrostatic, ...

Abstract: A flexure-based ankle rehabilitation device utilizes the linear elastic force-deflection characteristics of certain types of flexure beams to measure the forces and torques output by the human ...

Abstract: Carbon nanotubes (CNTs) may be used to create nanoscale compliant mechanisms that possess large ranges of motion relative to their device size. Many macroscale compliant mechanisms contain compliant ...

Abstract: Quasi-kinematic couplings (QKCs) are alignment devices that incorporate elastic-plastic deformations to combine principles of elastic averaging and exact constraint to achieve precision alignment. ...

Abstract: We report on the accuracy of the pseudo-rigid-body model (PRBM) in predicting the behavior of a nanoscale parallel-guiding mechanism (nPGM) that uses two single-walled (5,5) carbon nanotubes ...

Abstract: In this paper, we present the design, analysis, and testing of an ankle rehabilitation device (ARD), the purpose of which is to improve the efficacy of ankle joint complex (AJC) injury diagnosis ...

Abstract: This paper focuses on the design and implementation of a percutaneous catheter-based device to provide physicians with an externally controlled tool capable of manipulating and cutting specific ...
