Zero-point of strain data representing the structural state without stress is hard to determine,
but change in strain can be accurately measured. It is a good choice to quantify the complex …

Covalent doping of single-walled carbon nanotubes (SWCNTs) can modify their optical
properties, enabling applications as single-photon emitters and bio-imaging agents. We …

Engineering structures are subjected to strain and deflection, due to various loads, and/or
environmental effects. It is, thus, of uttermost importance to monitor the strain condition of …

Non-contact and full-field strain mapping captures strain across an entire surface, providing
a complete two-dimensional (2D) strain distribution without attachment to sensors. It is an …

Short-wave infrared (SWIR; 850–1700 nm) upconversion fluorescence enables
“autofluorescence-free” imaging with minimal tissue scattering, yet it is rarely explored due …

This study reports next generation optical strain measurement with “strain-sensing smart
skin”(S4) and a comparison of its performance against the established digital image …

Under the working conditions of aero‐engine, the three‐dimensional composite deformation
of the blade is caused by the centrifugal force generated by high‐speed rotation and the …

Portland cement emits bright near-infrared photoluminescence that can be excited by light
wavelengths ranging from at least 500–1000 nm. The emission has a peak wavelength near …

Subsurface damage may remain undetected for long periods and accumulate until it leads to
structural failure. Non-destructive measurements of surface strain can provide critical data …

Structures in their service life are often damaged as a result of aging or extreme events such
as earthquakes or storms. It is essential to detect damage in a timely fashion to ensure the …
