LEWISBURG, Pa. - Senior biomedical and mechanical engineering students shared their senior design projects with the Bucknell campus community Monday in the annual Senior Design Exposition.

For the biomedical engineers, it was a first in school history. The inaugural class graduates this month and they showed five biomedical engineering designs at the poster and design exposition in the Dana Engineering Building. Two of the projects are being considered for patent applications.

All five worked with external mentors at Geisinger Health System in Danville, Pa., and Hershey Medical Center in Hershey, Pa.

Wide range of skills
Daniel Cavanagh, associate professor of biomedical and chemical engineering, said the broad range of student biomedical engineering senior design projects is "indicative of both the wide range of valuable skills and abilities our students have developed as well as the broad nature of the biomedical engineering field."

He said the external mentors, who have appointments in Urology, Pediatric Intensive Care, Life Flight and the Weis Center for Research, assisted greatly in providing students with the opportunity to identify, propose solutions, and fabricate devices for real-world biomedical challenges.

"These projects not only represent the culmination of our students' hard work over the past four years but also represent the decade of planning that has gone into making biomedical engineering at Bucknell a reality," said Cavanagh.

Biomedical projects
The exposition's biomedical engineering senior projects were:

  • A feedback system that alerts a surgeon during minimally invasive surgery when harmful force is being applied to patient tissue
  • A drug injection device for use on an emergency response helicopter
  • Electrical heating of a cryosurgical probe with quick removal after surgery
  • A process that eliminates steps and saves time in zebrafish embryo research
  • A manifold device that improves the mixing of several intravenous fluid inputs into one output

Mechanical engineer projects
The mechanical engineering teams highlighted the design, manufacture and function of nine separate projects, including:

  • A method of providing water to a mountaintop community in El Porvenir, Nicaragua
  • A design to analyze performance of snowmobile engines to make the vehicles in Antarctica more efficient
  • A design for a 19th century water mill for harnessing water power and creating clean energy
  • Redesign of various cranks to increase bicycle crank performance
  • A prototype of an animatronic monkey face capable of making facial expressions to be identified by autistic children
