Paul Zehr says the Iron Man-like "exoskeletons" will have practical benefits such as helping people with spinal-cord injuries walk.
He says they will also have military applications.
Zehr says now's the time to think about the practical and moral implications of the technology.
He will tackle the issues during a Sept. 20 talk at B.C.'s centre for spinal cord research and treatment at Vancouver General Hospital.
Zehr is the author of two books -- "Becoming Batman: The Possibility of a Superhero," and "Inventing Iron Man: The Possibility of a Human Machine."
