In cochlear implantation surgery, the appropriate placement of the electrode array into the cochlea is vital. Suboptimal placement of the electrode array may lead to reduced hearing performance and speech recognition after the surgery. Currently, there are methods to confirm the electrode position post-operatively (e.g. through a CT scan), but...

Sensory nerve roots (DRGs) that emerge from the spinal cord can be stimulated with electrodes to prevent neuropathic pain. Proper functionality of DRG stimulation strongly depends on electrode placement, and conventional pre-curved introduction shafts limit DRG coverage of the implanted electrode lead. The goal of this thesis is to design an...

Neural interface in the form of microelectrodes is used to monitor and treat spinal cord injury and other neurological disorders by the means of recording and stimulation. Despite the apparent result of these electrical interventions, understanding of the mechanism behind neural stimulation is still inadequate. The use of optical monitoring...

A comparative study of three different membrane electrode assemblies for electrochemical CO2 reduction is performed in a flowcell setup utilizing gaseous CO2 as a reagent. The membrane electrode assembly consists of a bipolar or exchange membrane, an Ag-mesh catalyst and a gas diffusion layer. The counterreaction occurring on the opposite of the...

Cellular stiffness plays an important role for several diseases such as atherosclerosis, malaria and cancer. Cellular stiffness can be derived by the velocity of a cell that is squeezed through a constriction channel. For example, a rigid cell will move slowly through the constriction channel and vice versa. In this research a microfluidic...

Electrochemical sensing is a powerful tool for the rapid detection of (bio)molecules in fluids, and is frequently used in clinical analysis and diagnostics. Diamond is arguably the best electrode material for its robustness, wide potential window, very low background current, biocompatibility and self-cleaning features.
Nowadays, there is a...

Over the last few years the need of new alternatives to traditional disease modelling, drug screening and toxicity tests has boosted the development of a new class of devices called Organ on Chip. These usually consist in a substrate or a well in which cells are cultured with the aim of differentiating them in a particular tissue lineage. With...

This thesis investigates the shear strain-driven energy harvesting performance of compliant piezoelectric composite material systems. A characterization study was performed to observe and quantify the piezoelectric shear coupling of two phase piezoelectric composite materials ranging from 0-3 (particulate) to 1-3 (fiber) composites. To this aim,...

An organ-on-chip device, called Cytostretch (Philips NV), that is capable of mechanically stimulating cultured cells, is the subject of this study. The device comprises a microthin PolyDiMethylSiloxane membrane that is highly elastic, on which titanium nitride electrodes have been embedded. Its utility is projected in cardiac research to emulate...

The need for Cochlear Implants (CI's) with improved functionality and quality requires new techniques to be used to manufacture the electrode array. Titanium nitride (TiN) is one of the contenders for use as metal in the future CI's, but its characteristics need to be verified, measured and tested. A metal should comply to certain requirements...

Electroencephalograph (EEG) is used in various applications such as diagnosing patients suffering from epilepsy or seizures. Motion artefact is the noise recorded together with the desired biopotential signals. It is mainly introduced by the relative motion between the measurement electrode and the human scalp. Dry electrodes are preferred in...
