Model Course ePortfolios
BME 441.01, Senior Design Project in Biomedical Engineering, Spring 2011
Introduction to product development from the perspective of solving biomedical, biotechnological, environmental, and ergonomic problems. Teamwork in design, establishing customer needs, writing specifications, and legal and financial issues are covered in the context of design as a decision-based process. A team design project provides the opportunity to apply concepts covered in class. Formulation of optimal design problems in biomedical and physiological settings. Introduces optimization techniques for engineering design and modeling for compact and rapid optimization of realistic biomedical engineering problems. 3 credits.
Instructor: Dr. Jonathan Liu
ePortoflios are a requirement for course completion.
Dr. Liu will join Dr. Gary Halada and Dr. Imin Kao and represent the Department of Engineering in the Making Connections - Connecting to Learning project involving integrative learning and eportfolios. They also have applied for a NSF grant for developing a problem-based learning model which includes the eportfolio process. For more information on eportfolios and the project, contact Nancy Wozniak in The Faculty Center, ext. 22780. firstname.lastname@example.org
Previous methods of cellular electrophysiology measurements have relied primarily on electrical stimulation by means of microelectrode or voltage clamp setups. However, such implementations are often limited physically by electrical interference, monetarily by exorbitant device costs and logistically by electrode fragility and size limitations. As such, a new focus within the field of cellular stimulation has been optogenetics which employs the use of focused light to stimulate genetically engineered cells containing light sensitive ion channels. An optical stimulation system would offer a higher degree of spatial resolution, an increased maximum stimulation frequency and decreased electrical interference.
The Optical Pacemaker Group has been presented the challenge of creating such a stimulation system. The key objectives of the project are to create a modular and easily programmable device which allows for user defined pacing protocols. The device must effectively and reproducibly cause cardiac cellular excitation. Furthermore, such design objectives must be met while maintaining a maximum budget of $1000.
