Effect of contact pressure on porcine postmortem brain tissue impedance. - In: Proceedings of International Workshop on Impedance Spectroscopy, IWIS 2022, (2022), S. 36-40
In this experimental study we demonstrate the influence of contact pressure on porcine postmortem brain tissue impedance using a movable electrode array and a load cell. We show that the variation of the contact pressure between the tissue and the measurement probe leads to a coefficient of variation in the measured impedance of under 3%. Its influence can therefore be neglected in the investigated use case. Further, we fit the measured impedances to an equivalent circuit model and compare the resistance of grey and white matter brain tissue based on the model parameters.

2.5D etching of silicon dioxide for optical and photonic structures. - In: 2022 IEEE Photonics Conference (IPC), (2022), insges. 2 S.
We investigated the ability to control the sidewall-angle for the etching of SiO2 by tuning process parameters. We found a strong correlation between sidewall-angle and temperature, enabling control of the sidewall-angle from 60˚-90˚, and found a curved etch profile which was named quasi-isotropic.

Manufacturing of nanostructures in silicon carbide using UV-nanoimprint lithography in combination with fluorine-based plasma etching. - In: 2022 IEEE Photonics Conference (IPC), (2022), insges. 2 S.
The combination of a multi-layer resist system for soft UV-NIL with a fluorine-based plasma etching is investigated to elaborate homogeneously distributed nanosized features in silicon carbide. Initial studies substantiate that this approach can be a timesaving and cost-effective alternative to generate nanostructures in SiC.

Validation of integrated EV chassis controller using a geographically fistributed X-in-the-loop network. - In: 2022 IEEE Vehicle Power and Propulsion Conference (VPPC), (2022), insges. 7 S.
This paper presents the validation of an integrated chassis controller that unites three groups of actuators for the electric vehicle (EV) with independent in-wheel electric motors (IWMs) for each wheel. Controlled actuators are the IWMs, the active suspension, and the braking system. The models of test benches and the designed architecture of the X-in-the-loop network are presented. The proposed design approach allows testing the developed controller on a vehicle model in real-time and on hardware components.

Brake blending design using distributed and shared X-in-the-loop test environment. - In: 2022 IEEE Vehicle Power and Propulsion Conference (VPPC), (2022), insges. 6 S.
Brake blending design is a complex task in the development of electric vehicles (EV) and requires coordinated control on electric powertrain and friction brake system. The presented study discusses the architecture, control strategy, and functional validation of the brake blending as applied to an all-wheel drive EV equipped with four in-wheel motors (IWMs) and the decoupled electro-hydraulic brake system. The main focus is on the use of distributed and shared X-in-the-loop (XIL) test environment as a relevant development methodology enabling a wide spectrum of validation procedures. The paper introduces XIL-based experiments, where the brake blending operation has been evaluated for several test scenarios as the service braking and the Worldwide harmonized Light Duty Test Cycle (WLTC).
