2018 Three-in-Five Grand Prize Winners Hilary Johnson and Sally MillerGRAND PRIZE: "A Novel Lead Garment Structural System to Alleviate Orthopedic Stress for Surgeons" (DMD2018-6920)

Cardiovascular, orthopedic, and interventional radiology procedures using fluoroscopy require healthcare professionals to wear heavy lead garments for radiation protection. Wearing lead for prolonged periods can lead to musculoskeletal injuries, discomfort, and fatigue. This innovative mobile lead garment frame mitigates these negative outcomes by moving the lower garment load off body to a structural frame and redistributing the upper load from the shoulders to the hips through a torso frame. The device is compact and maximizes the limited space available in operating rooms, while still giving the surgeon adequate mobility. Preliminary analysis of device effectiveness was conducted by utilizing muscle activated electromyogram EMG sensors and qualitative surgeon user feedback surveys. The device is ready for extended user testing and commercialization.

Sally Miller, Department of Mechanical Engineering, Massachusetts Institute of Technology
Sally Miller recently completed her bachelors and masters at MIT in mechanical engineering, with a focus in mechanical design and product design. She enjoys exploring ways of combining engineering with her other passions, which include art and the outdoors.


2018 Three-in-Five 2nd Place Winner Erik Zavrel2ND PLACE: "A Novel Genioglossal Strengthening Device for Obstructive Sleep Apnea Treatment" (DMD2018-6809)

A number of clinical studies have demonstrated that strengthening the genioglossus via oral exercises, playing of a musical wind instrument, or hypoglossal nerve stimulation can result in significant reductions in the severity of Obstructive Sleep Apnea. We have developed embedded and PC versions of an electromechanical, biofeedback genioglossal training device that is intuitive to use and can quantitatively track changes in genioglossal strength and fatigability.

Erik Zavrel, 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.

2018 Three-in-Five 3rd Place Winner Yasemin Sarigul-Klijn3RD PLACE: "Gait Rehab Adaptive Machine: Design of GRAM, A Walking Linkage Powered Wheelchair for Lower Body Therapy and Assistance" (DMD2018-6816)

Therapy options for those with walking disability are limited by cost and complexity. GRAM is a low-cost wheelchair attachment that couples walking therapy to wheelchair propulsion, helping patients get around and get better.

Yasemin Sarigul-Klijn, Robotics, University of California, Irvine
Yasemin just completed her Ph.D. in Robotics from the University of California, Irvine. She is currently seeking new opportunities in industry and academia.
