COLLEGE OF ENGINEERING AND SCIENCE 2021 SENIOR PROJECTS CONFERENCE PREPARING ENGINEERS AND SCIENTISTS FOR TOMORROW WELCOME Welcome to the 2021 College of Engineering and Science Undergraduate Senior Projects Conference! We are excited to have alumni, parents, faculty, students, and friends of the College attend this conference. Your attendance helps us provide our senior students with a forum to exhibit technical and soft skills that they have learned in their curricula. During the conference, you will have the opportunity to see how our undergraduates have overcome limitations due to the coronavirus pandemic to solve a variety of problems, often resulting in deliverable prototypes. Many of the projects presented today will have an immediate impact for industrial and government sponsors, saving them time and money. Other projects add to ongoing faculty research, and some projects provide solutions for more generalized problems in engineering and science. Each project tackles an ongoing challenge that we must address. We hope that you will participate in this event by completing evaluation forms that are available in the presentation rooms. Your objective assessment of the students’ work and the quality of the presentations is extremely valuable to us and is used by many of our programs as part of their continuous improvement process. Also, please feel free to suggest topics for future projects and ideas for improving the conference. Our shared goal is to strengthen and enhance the preparation of our graduates for the transition into professional practice. Thank you for helping us achieve that goal.

Administration of medications in an ambulance saves time and lives. Unfortunately, keeping these medications at the appropriate temperatures of 2-8°C in an ambulance poses many challenges, including temperature stability, availability of space, power consumption, heat output, and securability. Penguin Paramedic is a medical refrigeration device that maintains cool medication temperatures in an ambulance for patients receiving pre-hospital care in order to increase stability of temperature- sensitive medications. The device achieves this outcome by utilizing thermoelectric coolers controlled by a negative feedback loop. These small coolers provide the necessary temperature range for medication storage without expelling large quantities of heat while also minimizing power consumption. Introducing the Penguin Paramedic into ambulances would expand storage capabilities in pre-hospital settings, save time in emergency rooms, and prevent medication waste.

Our device focuses on addressing this issue with anchoring methods and aids to improve spinal cord stimulation (SCS) anchoring procedures. The device is designed to have a simple and intuitive deployment while maintaining a secure lead position over long-term applications. During SCS surgeries, leads are stabilized to the fascia through anchoring techniques which vary between physicians. Lead migration can be traced back to improper anchoring techniques and has resulted in treatment failure and revision surgery. Our goal is to minimize current errors in manual anchoring methods for physicians to reduce surgical time, cost, and lead migration. By addressing these three major factors, a device has been created that will optimize SCS anchoring procedures. This device will offer a semi- automated method of securing the percutaneous leads to the fascia, increasing the technique’s availability to medical personnel.

The loss or malformation of an upper limb can greatly impact one’s ability to participate in everyday and common activities. This may motivate one to use an adaptable device and/or prosthetic as it will allow individuals to better participate in these activities. Our client, a ten-year-old female whose upper limb difference was caused by Amniotic Band Syndrome, has no phalanges with partial palm formation, and maintains full wrist flexion/extension. The client can perform most tasks without assistance and only requires occasional adaptations to participate in certain activities. Her inability to properly grip objects with her left hand presents difficulties—especially, in the form bike riding. So, an adaptive device was designed to give the client more control for steering and balance while riding her bike. It is an attachment to the bike that can be removed and reattached to any standard bike handle, can securely attach to the limb, allows the client to maintain 75% of her wrist flexion, and costs ≤$75 in raw materials to manufacture.

The disturbance, caused by the “ticking” noise of the valve closing, greatly impedes on a patient’s quality of life. Our team has addressed the decrease in the quality of life of mechanical heart valve recipients by reducing the closure noise of a mechanical heart valve. To be considered a functioning heart valve, each design had to exhibit several measurable factors taken from ISO 5840 standards before their noise magnitude could be compared. If the valve was considered functionally sound, the valve’s closure noise level was compared to the control valve’s noise level to determine whether the design significantly altered the sound magnitude.

Brace Ankle injuries are one of the most common injuries around the world. The standard procedure for treating ankle injuries is to allow full incremental weight-bearing and mobility with rest. The current devices on the market either utilize specific materials to reduce the forces on the ankle for adequate weight bearing practice with full immobilization of the ankle, like an Aircast, or allow for free range of motion of the ankle, like the Bionic Stirrup Ankle Brace. Orthopedic boots and stiff ankle casts do not allow for ankle movement, and other devices like braces do not provide any ROM limitations. There are no mainstream devices that allow for a comfortable transition from full immobilization to free motion. The A.A.R.M. Brace, the Adjustable Ankle Range of Motion Brace, will allow consumers to transition gradually from complete ankle immobilization to free range of motion in order to encourage accelerated healing. This gradual transition will be accomplished utilizing physical pins that will be adjusted by a physician or physical therapist as they feel the patient is able to withstand settings comfortably.
