BBCE Fall 2022 Capstone Projects

December 21, 2022

Students in the Department of Biomedical, Biological and Chemical Engineering conclude their coursework with a group capstone project. With these projects, students apply what they’ve learned in their classes and work together to study real world challenges and offer recommendations to those problems.

The experience gives students the hands-on preparation they need to be successful after graduation.

Chemical engineering students complete the American Institute of Chemical Engineers student design competition as their capstone project. This year’s subject was to design a pyoil purification system and provide possible solutions for the improvement of the Bali waste sorting facilities.

The group created a plant design model that used only one distillation tower instead of multiple towers to save costs. The design was powered using utilities of cooling water, high pressure steam, low pressure steam and electricity.

They also recommended the Bali facility can be improved through enhanced local marketing to improve participation of the waste collection program and place a greater emphasis on waste pre-sorting on a participant level.

Biomedical and biological students worked in groups to design devices or systems for biomedical or biological processes.

One group created a customizable prototype for dressing vacuum-assisted closures that are used to treat traumatic wounds. The prototype needed to fit all hand sizes, use existing sponge material, compatible with existing vacuum technology, reduce the current application time and reduce the number of leaks between the hand and adhesive cover.

Their completed design decreased application time by 75% but had small leaks. However, they believe professional manufacturing of the prototype, allowing the sponge to be built in once piece, would eliminate these leaks.

Another group developed a device to measure the Capillary Refill time (CRT) of pediatric patients objectively, consistently and precisely. The final device was a cellphone-based system that allows the imaging of a patient’s finger or forehead from a user’s personal mobile device.

The rigid phone holder provides consistency between tests and proper lighting for CRT measurements. The device includes JavaScript-based software to administer tests, analyze tissue images and compute and display CRT results in seconds. It is compatible with current handheld devices and only costs $1 to produce.

Below are the full capstone projects from the Fall 2022 semester. Take a few moments to learn how biomedical, biological and chemical engineers develop solutions to engineering problems.
