Smart Motor Syringe System, Conard Chan, Jenny Chiao
Electrical Engineering
Syringe pumps are widely used in many research applications especially in the applications that need precise control. Today most medical research utilizes syringes to control the fluid being pumped to the experiment objects. In most cases microscopic or nano-scopic motion control is required to acquire optimal results, such application includes purification of DNA/RNA from contaminants[1]. The high precision required to control the syringe pump makes it difficult to perform manually. This paper focuses on the design of an intelligent syringe pump motor control system to achieve reliable and precise control for biomedical experiments. This project improves medical research quality with …

Purdue Journal of Service-Learning and International Engagement
EPICS is a service-learning design program run through Purdue University. It strives to teach students design skills through providing for individuals, communities, and organizations in the surrounding area while mirroring engineering industry standards. BME (Biomedical Engineering) is a team within EPICS that strives to serve community partners through biomedical applications. William Sevick is an elementary school student with a congenital arm amputation. William and his family have been working with the BME team for the past three years designing assistive devices with the purpose of improving his actions in daily life such as eating, playing games, and riding his bike.
An Improved Method For Hospital Acquired Pressure Ulcer (Hapu) Prevention, Megan Morrissey, Jillian Yeager, Julia Beekman
An Improved Method For Hospital Acquired Pressure Ulcer (Hapu) Prevention, Megan Morrissey, Jillian Yeager, Julia Beekman
Honors Theses
Hospital acquired pressure ulcers (HAPUs), also called bedsores, are damage to the skin and/or underlying tissue caused by prolonged pressure on the bony areas of the body, with around 20% of pressure ulcers occurring in the heel region. Currently, the most common practice for HAPU prevention is arbitrary manual repositioning of patients by nurses every 1-2 hours. The goal of our project was to address HAPUs in the heel region of low mobility patients through an ulceration risk sensing system. Our team has created a wearable ulceration risk assessment system that combines individual patient risk data with real time pressure …

Scholars Symposium
The project goal is to design a low cost prosthetic hand controlled by a PIC18F25K22 microcontroller that will allow the user to perform simple tasks that require a greater dexterity than what a mechanical prosthetic can deliver. The digits of the prosthetic will be contracted or relaxed using electromyographic signals measured by electrodes on a single muscle group. Grip settings, which define the open and closed position for each digit, are used for the control of the hand. This allows common actions, such as grabbing a door handle or pencil, to be accomplished with readings from one muscle group instead …
Lower Extremity Exoskeleton, Kelly Haslett, Jacalyn Everhart
Lower Extremity Exoskeleton, Kelly Haslett, Jacalyn Everhart
Williams Honors College, Honors Research Projects
Develop a lower extremity device that provides assistance, support, and gait correction for children with cerebral palsy who display crouch gait as a symptom. The device will be designed for children ages 7-12. The device will be adjustable to accommodate varying levels of gait irregularity, weakness and human growth. The device would assist walking and stair climbing by providing bilateral support at hips, knees and ankle joints. The device will be designed for ease of donning and doffing. Battery, drive and control electronics will be designed to reside in a minimalistic backpack (outside the scope of this project).

Prosthetic Hand, Nicholas Damiani, Eric Rassavong, John Zolton
Williams Honors College, Honors Research Projects
Development of a prosthetic hand for an above-the-wrist amputee. The hand will provide flexion and extension of the wrist, fingers and thumb. The device will be customized for each individual by utilizing an medical imaging of the amputation side stump and the normal arm/wrist as the input. An integral hand/wrist and socket will be 3D printed, and actuators will be mounted to the prosthetic to provide motion. The wrist will be a mirror-image of the normal hand. Materials utilized will be selected based on the medical image intensity for different tissue types (cartilage, bone, skin, fat, etc.) and will simulate …
Adaptive Bike Pedals, Norman Hansen, Robert Csaky
Adaptive Bike Pedals, Norman Hansen, Robert Csaky
Williams Honors College, Honors Research Projects
The Adaptive Bike Pedals project is set out to create a new attachment for tricycle pedals that improves on a previous model. The need for these attachments is common in rehabilitation and physical therapy centers to help patients keep their feet on pedals when they are not able to. They can also be used in homes of families that have children with disabilities, diseases, or disorders that inhibit them from keeping their feet on the pedals. There are attachments on the market already, but the problem with those models is that they are costly and made for specific pedals. The …

Upper Extremity Mobility Device, Timothy J. Grassi, Jacob R. Miller
Williams Honors College, Honors Research Projects
The goal of this project was to evaluate a clinical problem, explore possible solutions, and produce a functioning prototype that would conform to all the established guidelines and requirements. The project focused on developing an upper extremity mobility device for a singular client with limited muscle activity in his arms due to childhood polio. Our design process was governed by an adapted form of the FDA Design Control Process, 21 CFR 820.30 [1]. The outcome of this project was a functioning prototype that utilized the concept of a motorized pulley system remote controlled using a key fob. This research project …

Williams Honors College, Honors Research Projects
The natural environment poses a significant number of obstacles and dynamic settings that makes mobility difficult for those with physical and mobility impairments. To approach this problem, a suspension was designed using inspiration from the early Mars rovers developed by NASA for traversing the varied Martian landscape. The course of the project followed the direction of a start-up through problem identification, early design generation and review, and final design production. The project outcome, through client request and proven market research, aimed to produce a multi-terrain wheelchair. The final product is a kinematic body with mobile front “legs” and a rotational …
