Meridian Ballrooms 2/3, The Commons Hotel


2017 Three-in-Five Winner Erik ZavrelGrand Prize: "An Active Distal Limb Warming Device for Insomnia Treatment" DMD2017-3469

The motivation for an active distal limb warming device as a treatment for insomnia is based on the established functional link between distal vasodilation and sleep induction. Somewhat counter-intuitively, heating of hands and feet can induce distal vasodilation, promote net body heat loss, and facilitate sleep onset. Preliminary results indicate that localized heating of hands and feet using our device increases distal skin temperature and decreases distal-proximal skin temperature gradient, which is the best physiological predictor for the rapid onset of sleep.

Erik Zavrel, Department of Biomedical Engineering, Cornell University
Erik Zavrel is a PhD candidate in the Department of Biomedical Engineering at Cornell University. His research focuses on the development of novel non-pharmacological device-based interventions for sleep disorders. He conducts clinical trials at Weill Cornell's Center for Sleep Medicine in New York City.


2017 Three-in-Five Winner F. Zeynep Temel2nd Place: "Pop-up-Inspired Design of a Septal Anchor for a Ventricular Assist Device" DMD2017-3458

We report design, fabrication and testing of a new origami-inspired pop-up septal anchor device. We exploit the emerging technology of pop-up MEMS in order to fabricate a collapsible anchoring mechanism. The pop-up anchor can be deployed into the left ventricle via a standard delivery sheath. We validate the load bearing ability of the anchor and demonstrate deployment in an ex vivo simulation.This is the first proposed medical device implant application using pop-up fabrication methods.

2017 Three-in-Five Winner Yue Chen3rd Place (Tie): "An MRI-Compatible Robot for Intracerebral Hemorrhage Removal" DMD2017-3451

One in 50 people will have an intracerebral hemorrhage in their lifetime (one every 8 minutes in the USA), with a 43% mortality rate. We propose the application of a steerable needle guided by continuous high resolution magnetic resonance imaging to rapidly relieve the pressure in the brain through blood removal. This device has the potential to provide safe and accurate decompression without disrupting healthy brain tissue as is currently done in open surgical procedures.

Yue Chen, Mechanical Engineering, Vanderbilt University
Yue Chen received the BS degree (first class honors) in Vehicle Engineering from Hunan University, Changsha, China, in 2010, and the M.Phil degree in Mechanical Engineering from The Hong Kong Polytechnic University, Hong Kong, in 2013. He was a graduate student at the College of Engineering, University of Georgia, Athens, GA, USA. He is now studying in the Department of Mechanical Engineering, Vanderbilt University, Nashville, TN, USA. His research interests include medical robotics and image guided therapies.


Zavrel3rd Place (Tie): "The Design and Development of Active Compression Garments for Orthostatic Intolerance" DMD2017-3480

This research explores the design and development of active compression garments for orthostatic intolerance using shape memory alloy (SMA) spring actuators. Current compression garments are made from spandex-type elastic materials with static compression or controllable inflatable compression sleeves. SMA controlled compression garments (SMA-CG) offer an alternative with a low-profile form factor that is easy to don/doff and provides dynamic control. This study focuses on optimizing the performance and pressure output of SMA-CGs through pressure testing and functional design solutions.

Julia Duvall, Apparel Design, University of Minnesota
Julia Duvall is a second year Apparel Product Development masters student and research assistant in the College of Design’s Wearable Technology Lab. Through her past internship experiences at NASA’s Johnson Space Center she developed wearable technology and astronaut clothing for human space flight. Her research interests include garment actuation and functional clothing development for extreme environments.
