Electromagnetic characterisation of flexible conductive membranes at millimetre-waves

Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Luc Maffli, Pietro Romano

Presented is the experimental surface impedance characterisation of stretchable conductors at Ka-band, using a non-contact technique based on two-port rectangular waveguide measurements. Two different types of metallisations are analysed, namely gold ion i ...

Electrophysiological imaging of epileptic brain slices reveals pharmacologically confined functional changes

Diego Ghezzi

Microelectrode arrays (MEAs) are employed to study extracellular electrical activity in neuronal tissues. Neverthe- less, commercially available MEAs provide a limited number of recording sites and do not allow a precise identifi- cation of the spatio-temp ...

Large-scale, high-resolution electrophysiological imaging of field potentials in brain slices with microelectronic multielectrode arrays

Diego Ghezzi, Luca Berdondini

Multielectrode arrays (MEAs) are extensively used for electrophysiological studies on brain slices, but the spatial resolution and field of recording of conventional arrays are limited by the low number of electrodes available. Here, we present a large-sca ...

Remotely Powered Wireless Cortical Implants for Brain-Machine Interfaces

Kanber Mithat Silay

Brain-machine interfaces hold promise for restoring basic functions such as movement or speech for severely disabled patients, as well as for controlling neuroprosthetic devices for amputees. One of the major challenges of clinically viable neuroprostheses ...

Low-Noise, High-Density Microelectronics for Multi-Mode Screening of Excitable Biological Cells

Urs Alexander Müller

In the past decades, two recording tools have established themselves as the working horses in the field of electrophysiological cell research: the microelectrode array (MEA) and the optical fluorescence imaging. The former is a grid of miniature electrodes ...

Fabrication of soft gold microelectrode arrays as probes for scanning electrochemical microscopy

Hubert Girault, Andreas Stephan Lesch, Fernando Cortes Salazar, Dmitry Momotenko, Gunther Wittstock

Soft linear gold microelectrode arrays for high throughput scanning electrochemical microscopy (SECM) imaging were fabricated using the Aerosol Jet (R) printing technology. Nanoparticulate gold ink was printed on polyimide Kapton HN (R) thin films. After s ...

The Future of Intracranial EEG Recording in Epilepsy: a Technological Issue?

Alexandre Schmid, Catherine Dehollain, Mahsa Shoaran, André Mercanzini, Yusuf Leblebici

Intracranial EEG information used for epilepsy surgery has been provided from large widely spaced electrodes over a narrow bandwidth. However, over the last decades, research on animal and more recently on human, promoted by increased interest in developin ...
