Neeft, Tobias (author)Silicon wafers and solar cells are delicate components used in the semiconductor industries and energy industries. Handling and transportation can easily damage these components. Conventional handling methods with mechanical contact can cause various damages to these delicate surfaces. Air bearings can provide a solution by enabling an almost...master thesis 2023

Jouyaeian, A. (author), Fan, Q. (author), Ausserlechner, Udo (author), Motz, Mario (author), Makinwa, K.A.A. (author)This article presents a hybrid magnetic current sensor for contactless current measurement. Pick-up coils and Hall plates are employed to sense the high and low-frequency fields, respectively, generated by a current-carrying conductor. Due to the differentiating characteristic of the pick-up coils, a flat frequency response can then be...journal article 2023

van der Wielen, Matthijs (author)The use of optical fibres as distributed vision sensor within a contactless handling system is discussed in this study. The three primary light colours and a volume diffuser will be used to detect the edge of an object levitating on an air-bearing table. One building block of a bigger system is used that consists of one receiving fibre in the...master thesis 2022

Pijnenburg, Kees (author)Improved handling methods are required in order to decrease the manufacturing cost of solar cells and flat panel display. A potential method would be to use a contactless handling system based on air bearing technology. As the name implies, the substrate levitates on a thin film (~10 μm) of air. The viscous shear force is used to exert a lateral...master thesis 2022

Han, Y. (author), Yarovoy, Alexander (author), Fioranelli, F. (author)This research aims to develop a contactless, radar-based sleep apnea detection method. A novel identification approach for this is proposed, based on the envelope of UWB radar spectrograms and machine learning. The envelope of the spectrogram is extracted by an image-based method, followed by signal smoothing via variational mode decomposition ...conference paper 2022

Glavinić, Ivan (author), Muttakin, Imamul (author), Abouelazayem, Shereen (author), Blishchik, A. (author), Stefani, Frank (author), Eckert, Sven (author), Soleimani, Manuchehr (author), Saidani, Iheb (author), Kenjeres, S. (author)More than 96% of steel in the world is produced via the method of continuous casting. The flow condition in the mould, where the initial solidification occurs, has a significant impact on the quality of steel products. It is important to have timely, and perhaps automated, control of the flow during casting. This work presents a new concept...journal article 2022

PAPADOPOULOS, ILIAS (author)One of the main reasons that the efficiency drops from cell to module is the conduction losses. To increase the efficiency of the PV module, the produced charge carriers in the semiconductor materials should be transferred to the PV module terminals with minimum conduction losses. As an alternative to the conventional cells and modules...master thesis 2021

Mercuri, Marco (author), Lu, Yiting (author), Polito, Salvatore (author), Wieringa, Fokko (author), van der Veen, A.J. (author), Van Hoof, Chris (author), Torfs, Tom (author)Objective: Over the last two decades, radar-based contactless monitoring of vital signs (heartbeat and respiration rate) has raised increasing interest as an emerging and added value to health care. However, until now, the flaws caused by indoor multipath propagation formed a fundamental hurdle for the adoption of such technology in practical...journal article 2021

Hooijschuur, Rico (author)This thesis presents the development of a contactless sensing system and the dynamic evaluation of an air-bearing based precision wafer positioning system. The contactless positioning stage is a response to the trend seen in the high-tech industry, with the substrates becoming thinner and larger to reduce the cost and increase the yield. With...master thesis 2019

Salters, Ruben (author)In the industry motion systems with electric motors are used for transporting and positioning thin flexible substrates at high throughput rates. A possible alternative actuation solution could be to apply contactless air film actuators which make use of air bearing principles. The air film actuators use a thin film of air to levitate and propel...master thesis 2019

Gao, Yuan (author), Qiao, Tiezhu (author), Zhang, Haitao (author), Yang, Yi (author), Pang, Y. (author), Wei, Hongyan (author)During the operation of the belt conveyor, measuring speed of the belt conveyor is vital to the safe and efficient operation. In the existing measuring speed system, the measurement instrument is required contacting with the surface of the belt. The contact measurement method cannot avoid the occurrence of measuring error caused by slipping...journal article 2019

Jansen, Roy (author)In the electronics industry there is a trend towards the handling of larger and thinner sheets of silicon, for the production of wafers and solar cells. The flowerbed is a contact-less handler for these fragile substrates based on air bearing technology. By levitating the substrate on a film of pressurized air, mechanical contact is avoided and...master thesis 2018

Potma, Olivier (author)Seals are used throughout the technology spectrum to prevent products form leaving their container or preventing foreign products to enter. With the sealing of rotary parts like shafts the seal needs to not only provide sealing capabilities, but also simultaneously allow for the desired movement without too much friction or wear. This is often...master thesis 2017

Snieder, Jelle (author)In many industries, for example the semi-conductor and solar cell industry, production processes have to handle thin substrates such as wafers or solar cells. For economic reasons, the thickness of these substrates shows a decreasing trend over the years. This results in an increasing breakage rate of the substrates during the production process...master thesis 2017

Verbruggen, Niek (author)A new concept in the field of air-based contactless positioning has been explored. The concept is based on the variation of the outlet restriction of an actuator, which controls a net air flow starting from the inlet. The object to be positioned ‘floats’ on a thin air film with a thickness in the order of tens of micrometres. Since the film...master thesis 2017
