The real-time monitoring of facilities, particularly large facilities (such as rail transit systems, large bridges, and buildings), can provide information regarding their surrounding environment and ...

The figure shows the Brillouin-gain-spectrum map obtained along a 13-m single-mode silica fiber. The upper diagram marks a ~1.1-m strained section. The lower color plot displays the corresponding ...

This figure presents the results of distributed strain sensing over an approximately 100-m-long optical fiber utilizing BOCDR with periodic pseudo-random modulation. The top diagram illustrates the ...

Bio-inspired wind sensing using strain sensors on flexible wings could revolutionize robotic flight control strategy. Researchers have developed a method to detect wind direction with 99% accuracy ...

A project at Caltech has developed a fiber optic-based method to measure soil moisture in the shallow subterranean region between the surface and underground aquifers. Reported in Nature ...

In a recent article published in Scientific Reports, researchers presented a comprehensive study on the development and performance evaluation of silver-coated laser-induced graphene (LIG) strain ...

A strain-sensing smart skin developed at Rice University that uses very small structures, carbon nanotubes, to monitor and detect damage in large structures is ready for prime time. The "strain paint" ...

A hydrogel engineered with cell-like particles mimicking skin tissue achieves 99.9% compressibility and ultralow energy loss while generating its own voltage to sense strain without batteries.
