21世纪的摩天大楼可能会安装玻璃纤维神经,以便能让工程师们及时检测出混凝土中出现的应力和裂纹情况,而不用非等发展到后来能用超声波检查出来的严重程度。美国新泽西州纽瓦克理工学院开发的这种光纤神经网络也会使桥梁和隧道受益无穷。该网络利用直径为250微米的光缆,先是埋进浇注的混凝土中,待混凝土凝固后,就把测光设备连接在光纤的一头,由该设备发出的光就会透过另一端。如果混凝土出现裂隙
21st-century skyscrapers may be fitted with fiberglass nerves so engineers can detect the stresses and cracks in concrete in time, without waiting until they become sonicated later. The fiber optic neural network developed by the Newark Institute of Technology in New Jersey, USA, also benefits bridges and tunnels. The network uses optical fiber cables of 250 microns in diameter, first embedded in poured concrete, and after the concrete is solidified, the metering device is connected to one end of the optical fiber and the light emitted by the device is transmitted through the other end. If the concrete cracks
