RISOptimization of an Endoscopic Radiofrequency Ablation Electrode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Radiofrequency ablation (RFA) is an increasingly used, minimally invasive, cancer treatment modality for patients who are unwilling or unable to undergo a major resective surgery. There is a need for RFA electrodes that ...
Design and Optimization of a Contact Aided Compliant Mechanism for Passive Bending
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A contactaided compliant mechanism (CCM) called a compliant spine (CS) is presented in this paper. It is flexible when bending in one direction and stiff when bending in the opposite direction, giving it a nonlinear bending ...
Trade Space Exploration of Magnetically Actuated Origami Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Selffolding origami has the potential to be utilized in novel areas such as selfassembling robots and shapemorphing structures. Important decisions in the development of such applications include the choice of active ...
Tuning of a Rigid-Body Dynamics Model of a Flapping Wing Structure With Compliant Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for validating rigid-body models of compliant mechanisms under dynamic loading conditions using motion tracking cameras and genetic algorithms is presented. The compliant mechanisms are modeled using rigid-body ...
Topology Optimization Design of Resonant Structures Based on Antiresonance Eigenfrequency Matching Informed by Harmonic Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, we present a design methodology for resonant structures exhibiting particular dynamic responses by combining an eigenfrequency matching approach and a harmonic analysis-informed eigenmode identification ...
An Analytical Model for Nonlinear-Elastic Compliant Mechanisms With Tension–Compression Asymmetry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: While nonlinear-elastic materials demonstrate potential in enhancing the performance of compliant mechanisms, their behavior still needs to be captured in a generalized mechanical model. To inform new designs and functionality ...
Special Issue: Folding Based Mechanisms and Robotics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Over the past few decades, the centuriesold art of origami and the centuriesold practice of engineering have been mixing in ways that have proven to be both fruitful and surprising, resulting in structures and mechanisms ...
Development and Validation of a Dynamic Model of Magneto Active Elastomer Actuation of the Origami Waterbomb Base
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Of special interest in the growing field of origami engineering is selffolding, wherein a material is able to fold itself in response to an applied field. In order to simulate the effect of active materials on an origamiinspired ...
On the Design and Testing of an Origami Inspired Nasal Cover: Mitigating Aerosol Risks During Endoscopic Sinus Procedures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aerosols generated during endoscopic sinus procedures present a concern to the health and safety of healthcare personnel, especially with the presence of coronavirus disease (COVID-19). The purpose of this study is to ...
Design, Fabrication, and Modeling of an Electric–Magnetic Self-Folding Sheet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A concept recently proposed by the authors is that of a multifield sheet that folds into several distinct shapes based on the applied field, be it magnetic, electric, or thermal. In this paper, the design, fabrication, and ...
