Fiber Optic Sensor Monitors Wear on Canadian Bridge

Engineers from the University of Toronto's Institute for Aerospace Studies and department of civil engineering, along with technicians from Ontario, Canada's Ministry of Transportation, have installed experimental long-gauge fiber optic sensors on a bridge in Toronto.
Scientists incorporated the sensors in a wrap of extremely strong and lightweight carbon- or glass-fiber-reinforced synthetic material. The sensors measure the expansion or contraction of the bridge, providing valuable data on the progress of corrosion in a column.
