A modular multiple frequency inductive link to wirelessly power multiple miniaturized implants
Sandro Carrara, Diego Ghezzi, Gian Luca Barbruni
A modular multiple frequency coils inductive link system to wirelessly provide power for at least a medical implant at an output of a receiving coil, whereby the receiving coil is configured to be implanted in an organism. The modular multiple frequency co ...
2024Inversing the actuation cycle of dielectric elastomer actuators for a facial prosthesis
Yves Perriard, Yoan René Cyrille Civet, Paolo Germano, Alexis Boegli, Thomas Guillaume Martinez, Stefania Maria Aliki Konstantinidi, Quentin Philippe Mario De Menech
Dielectric Elastomer Actuators (DEAs) are a type of smart material described as compliant capacitors. They show impressive performances as soft actuators, such as a high strain and fast response. Nonetheless, replicating natural muscle function with DEAs h ...
Society of Photo-Optical Instrumentation Engineers (SPIE)2024Power Aware Placement of On-Chip Voltage Regulators
In traditional power delivery networks, the on-chip supply voltage is provided by board-level converters. Due to the significant distance between the converter and the load, variations in the load current are not effectively managed, producing a significan ...
Piscataway2024Impact of beam-coupling impedance on the Schottky spectrum of bunched beam
Tatiana Pieloni, Nicolas Frank Mounet, Christophe Emmanuel R. Lannoy
The Schottky monitors of the Large Hadron Collider (LHC) can be used for non-invasive beam diagnostics to estimate various bunch characteristics, such as tune, chromaticity, bunch profile or synchrotron frequency distribution. However, collective effects, ...
Iop Publishing Ltd2024Pseudo-Three-Dimensional Analytical Model of Linear Induction Motors for High-Speed Applications
Mario Paolone, André Hodder, Lucien André Félicien Pierrejean, Simone Rametti
Literature on linear induction motors (LIMs) has proposed several approaches to model the behavior of such devices for different applications. In terms of accuracy and fidelity, field analysis-based models are the most relevant. Closed-form or numerical so ...
2024The magnet feeders for the European DEMO fusion reactor: Conceptual design and recent advances
Rainer Wesche, Roberto Guarino, Frédéric Michel
The magnet feeders are part of the critical systems of a fusion reactor since they represent the interface between the in-cryostat components at 4.5 K and the room-temperature cryogenic plant and power supply. The European DEMO tokamak foresees 16 toroidal ...
Lausanne2024Ripple Voltage and Loss Reduction of Single-Phase ISOP SST by Eliminating the Second Harmonic Current in LLC Converters
Drazen Dujic, Andrea Cervone, Tianyu Wei
In two-stage solid-state transformers with input-series output-parallel structure, the LLC converter operating at a fixed switching frequency is a common choice for the isolated DC/DC conversion stage because it can provide a high efficiency and a fixed vo ...
2024Instabilities in Elastic and Magneto-Elastic Beams and Shells: from Shell Buckling to the Design of a Programmable Braille Reader
In this thesis, we conduct a comprehensive investigation into structural instabilities of both elastic and magneto-elastic beams and shells, resulting in a creative proposal to design a programmable braille reader. Methodologically, we combine numerical si ...
EPFL2024Morphological and Material Programability of a Hall-Effect Based Soft Tactile Sensors
Josephine Anna Eleanor Hughes, Sudong Lee
The different receptors in human skin show not only diversity in the stimuli to which they respond, but also variable sensitivity and directionality. This is often determined by their location or morphology, and can play an important role in filtering or a ...
IEEE2024Nonlinear optical diode effect in a magnetic Weyl semimetal
Philip Johannes Walter Moll, Chunyu Guo, Hao Yang
Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Optical diode effects arising from the Weyl fermions have been theoretically co ...
