Medical Device Coatings
With Dr. Sina Shahbazmohamadi
Serious as a heart attack.
From the lab of Dr. Sina Shahbazmohamadi
Implantable medical devices like pacemakers and neurostimulators use specialized coatings that safely facilitate transfer of electrical charges. Since reliability is paramount, verifying the integrity of the coating microstructure is crucial.
Dr. Sina Shahbazmohamadi and team have designed a process where the use of non-destructive 3D X-ray tomography, in conjunction with a Focused Ion Beam-Scanning Electron Microscope (FIB-SEM), work together to target and tomographically image a specific region of a device at the nanoscale.
The ZEISS Crossbeam provides a detailed 3D map of coating cracks or defects. The testing is crucial to mitigating the dire outcomes from failure of these devices.
Surface characterization
Surface roughness determined by laser scanning confocal microscopy.
Multiscale analysis of coatings
Optical imaging and X-ray microscopy were used to determine roughness and irregularities in the coating interface, targeting a specific region of interest for high resolution 3D tomography with the FIB-SEM.
“When we don't see what we are looking for, we don't give up. Instead, we REFINE our resolution.”
