Instrumentation for Quantitatively Assessing Tremors

Instrumentation for Quantitatively Assessing Tremors

Team Members

Cody Alger, Jacob Gombar, Daniel Hirst, Michael Hulway, and Amy Saelen, Biomedical Engineering

Advisor

Dr. Keat Ghee Ong

Sponsor

Department of Biomedical Engineering

Project Overview

Currently there is no effective way to quantify the magnitude and frequency of essential tremors in the hands. Therefore, the goal is to design and build a device that quantitatively assesses these variables. This device must be able to record the frequency and magnitude of the tremor, with minimal interference from outside factors, while remaining cost-effective. In addition, this device must have a high level of precision and accuracy so the results can be compared to previous trials to determine trends in tremor behavior—as well as help determine whether specific treatments are having measurable effects in reducing the tremor.

Hand-Washing Compliance System

Hand-Washing Compliance System

Team Members

David Michael Smeenge, Cari Steinman, Zichen Qian, and Melinda Ylitalo, Biomedical Engineering; Britney Estola and Jennifer Lounds, School of Business and Economics

Advisor

Dr. Seth Donahue

Sponsor

Portage Health

Project Overview

The goal is to design a compliance system for hospitals to assess the occurrence of employee hand washing while in a patient’s room. The system must be cost-effective, easy to use, easily implemented, applicable to a variety of rooms, and compatible with the hospital and health care workers.

Fixation System Design for a Leadless Pacemaker

Fixation System Design for a Leadless Pacemaker

Team Members

Daniel Dubiel and Natalie Hartman, Biomedical Engineering; Beatrice Burgess and Brian Czech, Mechanical Engineering and Biomedical Engineering; John Kinzinger, Materials Science and Engineering; and Amberlee Lifer, Materials Science Engineering and Biomedical Engineering

Advisors

Dr. Rupak Rajachar, Biomedical Engineering, and Dr. Steve Hackney, Materials Science and Engineering

Sponsor

Medtronic

Project Overview

While traditional pacemakers pose risks of complications and infections, Medtronic’s leadless pacemaker is designed to reduce these risks by its sub-cubic-centimeter volume. This size is achieved through increased efficiency by attaching the pacemaker directly to the heart wall. Though effective, one of the greatest challenges associated with this technology can be found in the method of attachment, which served as the focal point for this project. Several attachment designs were developed, and the sponsor chose three of these for testing. Finite element analysis, as well as fluid shear testing and force-displacement testing, were completed on fabricated designs.

Bioabsorbable Metal Stent Degradation Simulation Design

Bioabsorbable Metal Stent Degradation Simulation Design

Team Members

Patrick Bowen and Jesse Gelbaugh, Materials Science and Engineering; Rebecca Franke, Judy Bryne, Ellen Pokorney, Jessica Rhadigan, and Aaron Tauscher, Biomedical Engineering

Advisors

Dr. Jeremy Goldman, Biomedical Engineering, and Dr. Jaroslaw Drelich, Materials Science and Engineering

Sponsor

Boston Scientific

Project Overview

Research has shown that the use of bioabsorbable materials in stents shows great promise in mitigating long-term, stent-related cardiovascular risks, as well as aiding the vascular healing process. Qualitative and quantitative relationships between the relatively slow in vivo degradation and faster in vitro degradation of bioabsorbable materials will be found in order to better understand how to simulate the behavior of these materials in the body. This project is meant to work toward a reproducible, well-defined protocol for conducting evaluations of candidate materials for use in bioabsorbable stents.

Reliability Testing Device

Reliability Testing Device

Team Members

Anthony Rossetto and Brittany Potton, Biomedical and Mechanical Engineering; Sam Bredeson and Brian Stetter, Biomedical Engineering

Advisor

Dr. Sean Kirkpatrick

Sponsor

Pioneer Surgical

Project Overview

The goal is to complete a prototype mechanism that can hold and automatically test a tensioning device. Along with automation, test values will be recorded for analysis. The ability to have the tensioner tested automatically will save work hours and preclude employee fatigue.
