Fiber Optic Sensor Monitors Wear on Canadian Bridge

Facebook X LinkedIn Email
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.
