Transient Electronics: Biodegradable Frequency‐Selective Magnesium Radio‐Frequency Microresonators for Transient Biomedical Implants (Adv. Funct. Mater. 39/2019)

Jürgen Brugger, Giovanni Boero, Matthieu Jean Michel Rüegg, Remo Blum

In article number 1903051, Matthieu Rüegg, Juergen Brugger, and co-workers design, fabricate, and characterize biodegradable magnesium microresonators using an innovative microfabrication process based on ion beam etching. Under a radio-frequency magnetic ...

Experimentally-constrained biophysical models of tonic and burst firing modes in thalamocortical neurons

Henry Markram, Sean Lewis Hill, Ying Shi, Werner Alfons Hilda Van Geit, Christian O'Reilly, Christian Andreas Rössert, Elisabetta Iavarone, Bas-Jan Zandt, Jane Yi

Somatosensory thalamocortical (TC) neurons from the ventrobasal (VB) thalamus are central components in the flow of sensory information between the periphery and the cerebral cortex, and participate in the dynamic regulation of thalamocortical states inclu ...

Drastic breakdown field reduction in multilayer DEA

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne, Morgan Almanza

The electrical properties such as the electrical breakdown and the permittivity but also the softness of the elastomer are key factors for the performance of DEA. In order to have the best use of elastomer films, single-layer actuators have been deeply stu ...

Electrical transport in onion-like carbon-PMMA nanocomposites

László Forró, Arnaud Magrez, Claudio Grimaldi, Maryam Majidian

We report electrical conductivity measurements of polymethyl-methacrylate filled by onion-like carbon particles with a primary particle size of approximate to 5 nm. We show that the conductivity sigma is exceptionally high even at very low loadings and tha ...

Electrical effects in winding of large electrical ac machines application to advanced large size DFIM

Frédéric Michael Maurer

To meet the electrical grid's demand on pump power variation, GE Renewable Energy develops since 10 years variable speed machines (also called Doubly Fed Induction Generators or DFIG). Within turbogenerators, the phenomenon of circulating currents in Roebe ...

High voltage switch for compact bidirectional dc-dc converter driving dielectric electroactive polymer actuators

Yves Perriard, Yoan René Cyrille Civet, Morgan Almanza, Raphaël Johannes Charles Mottet, Lucas Pniak

Driving DEAs requires time-varying high voltage power supplies, up to 18kV for 200um polymer layers. HV amplifiers are commonly used but bulky and expensive. Designing embedded actuators requires compact and efficient powersupplies. Furthermore, only a lit ...

Advantages of soft subdural implants for the delivery of electrochemical neuromodulation therapies to the spinal cord

Stéphanie Lacour, Marco Capogrosso, Grégoire Courtine, Eduardo Martin Moraud, Pavel Musienko, Ivan Rusev Minev, Nikolaus Wenger, Jérôme Gandar, Polina Shkorbatova, Nathan Antoine Greiner

Objective. We recently developed soft neural interfaces enabling the delivery of electrical and chemical stimulation to the spinal cord. These stimulations restored locomotion in animal models of paralysis. Soft interfaces can be placed either below or abo ...
