As Hermelinda Bristol learned more about anatomy, she began envisioning a frame with a tight waist belt and rigid supports for the legs. … But while she had the idea, she did not have the expertise to build something that was lightweight, flexible, and strong.
In May of 2016, Jeffrey’s sophomore year at the University of Arizona, she hit on an idea. The university has a highly respected engineering college. Why not enlist them to see if some of their students could help a fellow classmate?
A group of engineering students created a device to analyze these colors and chronologically date bruises, specifically those in child abuse cases.
The student team consists of five biomedical engineering students and one mechanical engineering student. The students are from places like Arizona all the way to Tehran, Iran; Chaiyaphum, Thailand; Ciudad Obregón and Sonora, Mexico and Beijing, China.
Engineering Design Day brought together 616 students, who worked on 118 industry- and faculty-sponsored projects over an academic year, vying for $36,250 in cash prizes. More than 120 industry judges assessed the projects.
“Be inspired by these young engineers,” said interim Dean Larry Head. “This is the precipice. This is the beginning of some really great things.”
Woodridge contacted UA’s engineering department. A group of six engineering students collaborated to design a device and test it a few months later. Woodridge said the device could be used to determine when abuse has occurred. After more testing, he hopes to distribute the portable, non-invasive device to medical facilities.
“The forensic ability to accurately determine the age of a bruise has long evaded the medical community, which hasn’t been able to answer questions about how old bruises are with any degree of accuracy,” said Dr. Dale Woolridge, director of the Southern Arizona Children’s Advocacy Center and professor of emergency medicine, pediatrics, and chemistry and biochemistry at the University of Arizona.
The project that took the top prize at Engineering Design Day 2017 was a drone designed to pollinate date palms. The College of Engineering has teamed up with the Eller College of Management’s McGuire Center for Entrepreneurship and the Yuma Center of Excellence for Desert Agriculture to help participating students create a startup to market the drone as part of the Go to Market Initiative.
The first interdisciplinary learning experience in the Go To Market initiative — recently launched by the UA College of Engineering, the McGuire Center for Entrepreneurship and the Yuma Center of Excellence for Desert Agriculture — is further development of the drone-based pollination system senior capstone project that won best overall design at Engineering Design Day 2017.
In 2017, Hermelinda Bristol partnered with six seniors Engineering Design Program seniors to adapt her non-motorized exoskeleton design that can allow her son, Jeffrey, to move and exercise his body parts independently while providing a system that helps develop a normal gait.
The semiautonomous aerial vehicle, which was featured in a video, even sounded like a swarm of bees flying over Medjool date palm trees at a nursery in Yuma, Arizona. The team of seniors that built it won the Raytheon Award for Best Overall Design.
Design Day is the culmination of the college’s Engineering Design Program, in which teams of five or six students spend an entire academic year taking sponsors’ projects from concept to reality.
This year sponsor Hermelinda Bristol recruited UA students, including biomedical engineering major Jason Keatseangsilp, to build an unpowered exoskeleton for her son Jeffrey, a UA junior in accounting with cerebral palsy.
Engineering affects virtually every aspect of our lives, and at the University of Arizona’s Engineering Design Day on May 1, more than 500 students intend to prove it.
The public is invited to see the displays in the Student Union Memorial Center Grand Ballroom and on the UA Mall from 11 a.m. until 4 p.m., and to attend the awards ceremony in the ballroom from 4 to 5:30 p.m., when industry sponsors will present more than $25,000 in cash prizes to project teams.
Students at the University of Arizona are teaming up with a former state trooper to develop a service to help people in need and the first responders who care for them during an emergency.
Vijilis is designed to coordinate resources and service providers during an emergency, to clear the scene of a crash or other emergency more quickly, in hopes of reducing the chance of a secondary crash.
Engineering Design Program project sponsor CardioSpark hopes to ease the grim statistics surrounding sudden cardiac arrest by placing networked automated external defibrillators, or AEDs, in Southern Arizona neighborhoods.
CardioSpark has solicited help from several teams of seniors “to help us flesh out the technology that is key to making our network viable and effective,” said Tom Colberg, CardioSpark’s chief executive officer.
