Explaining the inexplicable

So it turns out biomedical engineering is not a discipline that lends itself to 'layman's terms'.
A large part of my job is making head-splitting academic jargon sound like regular english so that people with arts degrees can understand it. It's challenging but I enjoy it and, I have to say, I have been quite successful in this aspect of my position at the uni. I have made sense of an inter-disciplinary, cross-sectoral regulation initiative, sustainable and renewable energy engineering, sustainable urbanism, and economic/resource geology. Biomedical engineering however, is proving to be more difficult.

What is it? Here are some key words:
X-rays (well we know that one)
micro device fabrication
kinematics
tele-medicine
fundamental biophysical measurement and sensors
optical microscopy

Really? Because I thought maybe it was the lamp at the end of the examination table. Huh.
