Localized delivery of drugs into articular cartilage (AC) may facilitate the development of novel therapies to treat osteoarthritis (OA). We investigated the potential of spark-gap-generated sound to deliver a drug surrogate, i.e., methylene blue (MB

Stroboscopic scanning white-light interferometry (SSWLI) can be used for 3D imaging of oscillating samples. It allows measurement of micrometer to millimeter size samples with nanometer vertical precision. Unlike coherent light source systems the SSW

Scanning white light interferometry (SWLI) is an established methodology for non-destructive testing of MEMS/NEMS. In contrast to monochromatic interference microcopy SWLI can unambiguously resolve surfaces featuring tall vertical steps. Oscillating

We addressed the question of how to assign confidence limits to the measured trajectory of a moving MEMS membrane. This was done by calibrating our SSWLI setup using a traceable piezoelectric transducer as a transfer standard. We calibrated our SSWLI

Silicon micromachining permits tailoring, for optimal device performance, the active membranes of capacitive micromachined ultrasound transducers (cMUTs). The membrane motion determines much of the transducer performance. In a thrust towards traceabl

A scanning white light interferometer can characterize out of plane features and motion in M(N)EMS devices. Like any other form and displacement measuring instrument, the scanning interferometer results should be linked to the metre definition to be

We report on building a broadband LED light source for stroboscopic white light interferometry. We chose phosphor types, mass ratios, and encapsulant, to tailor the necessary emission spectrum. Based on known emission spectra, we mixed combinations o
