In-vitro detection of small isolated cartilage defects: Intravascular ultrasound vs. optical coherence tomography

This experimental work focused on the sensor selection for the development of a needle-like instrument to treat small isolated cartilage defects with hydrogels. The aim was to identify the most accurate and sensitive imaging method to determine the location and size of defects compared to a gold standard (µCT). Only intravascular ultrasound...

The Design of a 2-DOF Inertial Motion Harvester for a Mechanical Watch

Energy harvesters extract energy from the ambient environment and can be used to power electronic devices. One interesting application of these harvesters is the medical field where in the future they might be used to power pacemakers or medicine pumps. One common energy harvester is the automatic wrist watch, a 1 degree of freedom (DOF)...
