Active pixel sensor array for high spatio-temporal resolution electrophysiological recordings from single cell to large scale neuronal networks

Kilian Imfeld, Luca Berdondini

This paper presents a chip-based electrophysiological platform enabling the study of micro- and macro-circuitry in in-vitro neuronal preparations. The approach is based on a 64 x 64 microelectrode array device providing extracellular electrophysiological a ...

Low noise, low power front end electronics for pixelized TFA sensors

Christophe Ballif, Matthieu Despeisse

Thin Film on ASIC (TFA) technology combines advantages of two commonly used pixel imaging detectors, namely, Monolithic Active Pixels (MAPs) and Hybrid Pixel detectors. Thanks to direct deposition of a hydrogenated amorphous silicon (a- Si:H) sensor lm on ...

Photoelectrochemical properties of sensitized thin films

Mohamad Hojeij

In recent years, the fabrication of novel ultrathin film systems featuring multi-functionalities has been extensively studied due to their potential applications in photonics, sensors and solar cells. In a general sense, the primary goal of the present the ...

Semiconductor Image Sensing

Peter Seitz, Nicolas Blanc

Silicon is an excellent detector material for electromagnetic radiation in the wavelength range of 0.1 to 1000 nm. In the visible spectral range (400-700 nm), external quantum efficiencies approaching 100% are obtained. When combined with the amazing minia ...

Copper / low-k technological platform for the fabrication of high quality factor above-IC passive devices

Modern communication devices demand challenging specifications in terms of miniaturization, performance, power consumption and cost. Every new generation of radio frequency integrated circuits (RF-ICs) offer better functionality at reduced size, power cons ...

Positional order in lead scandium tantalate (PST) as a "tool" for the investigation of relaxor ferroelectric behavior in thin films

Kyle Brinkman

Relaxor ferroelectric thin films exhibit a drastic reduction in the dielectric constant and associated properties in the thin film form, even for thicknesses in the micron range, which are essentially infinity for the size effects typically investigated in ...
