High-performance piezoelectric fiber sensor offers real-time landslide detection

A research team led by Dr. Lim Sang-kyu in DGIST's Department of Energy and Environmental Technology has developed a smart fiber sensor that can detect natural disasters such as landslides in real time. The new fiber is based on piezoelectric technology, which converts pressure into electricity. Its three-dimensional (3D) structure dramatically improves performance, facilitating the implementation of a self-powered sensor system that can operate without an external power source.
