The research objective of this research is to develop a measurement method that can measure thin film thicknesses through a multilayer that consists of both surrounding thick layers and in between thin films. An optical non-contact measurement method is researched and developed to non-destructively measure the thickness of a liquid thin film,...

Shape changing active metamaterial could form the structural backbone of an object as well as deliver the actuation. The integration of these two functions saves design space and allows for creative topologies. The literature study of this thesis investigated smart material actuator solutions that could be used to enable such active...

There is an ever-increasing demand for high data transfer rates. Laser satellite communication is a promising technology which offers high data rates and more secure links than the mature radio frequency (RF) communication. To make a laser communication terminal market viable it must be low size, weight and power (SWaP). The telescope drives the...

The central nervous system has a very limited capacity to regenerate damaged tissue. Therefore, regeneration strategies focus on transplantation of neural stem cells or differentiated neural cells. In order to make such a treatment effective, it is important to understand the mechanisms that enable cell differentiation. It is well known that...

Spinal fusion is a surgical treatment involving stiffening parts of the spinal column to eliminate any relative motion and improve spine stability. A critical part of spinal fusion surgery is the placement of pedicle screws because it is highly complex and can damage the vascular structures and nerves near the vertebrae. To prevent complications...

With climate change being a prime source of concern around the world, air pollution is a topic that requires special attention. Therefore, it is of utmost importance to track and measure the emissions in our environment for detecting the sources and understating the climate change so as to figure out possible solutions. Despite ongoing...

A research gap exists in a targeted drug delivery into the brain with an implant placed on the outer surface of the cerebral cortex. If an implant with spatial control that can release drugs to a target location can be developed, it will provide efficient treatment opportunities for a variety of brain disorders such as strokes. One of the...

Use of earth observation satellites have grown at a very high rate over the past few decades. On a closer observation of things around, most of them uses satellites, directly or indirectly. Satellites are being used in the day-to-day life without being aware of its application. Satellites are used for small things like weather report,...

The manufacturer of an electron beam lithography machine pushes a better understanding and higher performance of the optical column to provide a better product with each iteration. At the heart of the column is the source of electrons: the gun lens. It holds the field emitter from which the electrons originate and accelerates the beam to a first...

Introduction. In spinal surgery, the misplacement of spinal screws is a problem that causes (severe) pain, bleedings or even paralysis [2]. Screw misplacements are common as navigating in the spine is difficult due to the small vertebral dimensions and a lack of anatomical landmarks [3] [4]. In order to improve the navigational support of spine...

Neurosurgery is technically challenging because of the inaccessibility and sensitivity of the brain. The risk of complications for the patient is high and simulation-based training is therefore preferred. However, surgical training in cadavers and virtual reality is not satisfactory. A phantom is a model of organs or tissues consisting of tissue...

To study blood-related diseases, measurement methods must be developped to study cardiac and hematological parameters of a patient. Such methods should preferably be non-destructive, in-vivo, cheap, accurate and real-time. Light has great potential to achieve this.<br/>Using e.g. a pulse oximeter, it is possible to measure a patient’s heartbeat....
