Biomedical engineering is responsible for many of the dramatic advance
s in modern medicine. This has resulted in improved medical care and b
etter quality of life for patients. However, biomedical technology has
also contributed to new ethical dilemmas and has challenged some of o
ur moral values. Bioengineers often lack adequate training in facing t
hese moral and ethical problems. These include conflicts of interest,
allocation of scarce resources, research misconduct, animal experiment
ation, and clinical trials for new medical devices. This paper is a co
mpilation of our previous published papers on these topics, and it sum
marizes many complex ethical issues that a bioengineer may face during
his or her research career or professional practice. The need for eth
ics training in the education of a bioengineering student is emphasize
d. We also advocate the adoption of a code of ethics for bioengineers.
