Die Ernsting’s family Fashion-Retail-Studie analysiert das Kaufverhalten von Verbraucher*innen in Deutschland in der Modebranche. Neben der Darstellung des Status quo werden über mehrere Erhebungszeitpunkte Veränderungen in den Kauf- und Konsumgewohnheiten erfasst. Zusätzlich wird ein aktuelles Thema in einer Deep-Dive-Studie vertieft.
Angesichts der gegenwärtigen ökologischen Herausforderungen und der technologischen Innovationen in der Modeindustrie konzentriert sich die dritte Ausgabe auf die Analyse des nachhaltigen Kauf- und Konsumverhaltens von Verbraucher*innen in Deutschland. Daran anknüpfend befasst sich die Deep-Dive-Studie mit der Frage, wie sich unterschiedlich hohe Rücksendegebühren auf das Bestellverhalten von Online-Käufer*innen im Modehandel auswirken und welche Rolle das Umweltbewusstsein der Verbraucher*innen dabei spielt.
This study presents a comprehensive evaluation of force sensors manufactured through conventional CNC machining, laser powder bed fusion (LPBF), and material extrusion (MEX) 3D printing methods. The study utilized a combination of finite element method (FEM) simulations, functional testing, durability assessments, and ultimate strength testing in order to assess the viability of additive manufacturing for sensing technology applications. The FEM simulations provided a preliminary framework for predictive analysis, closely aligning with experimental outcomes for LPBF and conventionally manufactured sensors. Nevertheless, discrepancies were observed in the performance of MEX-printed sensors during ultimate strength testing, necessitating the implementation of more comprehensive modeling approaches that take into account the distinctive material characteristics and failure mechanisms. Functional testing confirmed the operational capability of all sensors, thereby demonstrating their suitability for the intended application. Moreover, all sensors exhibited resilience during 50,000 cycles of cyclic testing, indicating reliability, durability, and satisfactory fatigue life performance. Notably, sensors produced via LPBF exhibited a significant increase in strength, nearly three times that of conventionally manufactured sensors. These findings suggest the potential for innovative sensor design and the expansion of their use into higher-loaded applications. Overall, while both LPBF and conventional methods demonstrated reliability and closely matched simulation predictions, further research is necessary to refine modeling approaches for MEX-printed sensors and fully unlock their potential in sensing technology applications. These findings indicate that additive manufacturing of metals may be a viable alternative for the fabrication of biomedical sensors.
Unter dem Titel „DO-IT-YOURHEALTH!” wurde im Rahmen des “Coburger Wegs” und hier im Modul ⅔ “Interdisziplinäre Projekte” eine online Gesundheitsförderung vom 15.11.2015 bis zum 11.12.2015 an der Hochschule Coburg durchgeführt. Diese richtete sich an alle Studierende mit dem Ziel, deren Gesundheitsbewusstsein in den Bereichen Ernährung, Bewegung und Innere Haltung zu stärken.
Imaging methods by the means of optical sensors are applied in diverse scientific areas such as medical research and diagnostics, aerodynamics, environmental analysis, or marine research. After a general introduction to the field, this review is focused on works published between 2012 and 2022. The covered topics include planar sensors (optrodes), nanoprobes, and sensitive coatings. Advanced sensor materials combined with imaging technologies enable the visualization of parameters which exhibit no intrinsic color or fluorescence, such as oxygen, pH, CO2, H2O2, Ca2+, or temperature. The progress on the development of multiple sensors and methods for referenced signal read out is also highlighted, as is the recent progress in device design and application formats using model systems in the lab or methods for measurements’ in the field.
Optical sensors are often a combination of optical fibers or waveguides and sensitive layers which consist of organic or metal-organic dyes incorporated in a polymer or silica film which change their absorbance or photoluminescence (fluorescence or phosphorescence) properties due to interaction with the analyte molecules. The focus of this chapter is on the description of inorganic materials used in electrochemical sensors, because these found widespread applications in gas-sensors and ion-selective electrodes. The response of such sensors can be due to a change of inherent properties of the sensing material (conductivity, capacitance or permittivity) or a change of the measured current or voltage in an electrochemical cell (amperometric or potentiometric sensors).
