To best utilize power converters, a sound understanding of the relationship between the circuit topology and the power-semiconductor-device characteristics is required. This is especially important in high-frequency switching, where device parasitics start ...
To enable chemical speciation, monitoring networks collect particulate matter (PM) on different filter media, each subjected to one or more analytical techniques to quantify PM composition present in the atmosphere. In this work, we propose an alternate ap ...
Nowadays, no less than 21 sensors are used to monitor the health conditions of aircraft engines. However, the actual state of technology do not allow the measurements on moving parts in harsh environment (i.e. rotor shaft and blades). Thanks to its straigh ...
The increasing demand of higher frequencies technologies in RF (Radio frequency) components, especially for telecommunication, create a need to develop wider and higher frequency bands filters, with optimal performances. Thus, constant effort are made to d ...
Nowadays almost all the mobile networks use the 4G and will eventually soon use the 5G. To use this technology, devices need lots of band filters. This is why the Advanced NEMS laboratory of the EPFL is developing a new kind of MEMS resonant device at 5GHz ...
This paper presents the use of a novel type of resonators made of a thin membrane of Y-cut Lithium Niobate that has an array of interdigitated electrodes on the top, and a floating metal on the bottom. Each electrode gives rise to a quasi-independent reson ...
Neuromorphic computing is a wide research field aimed to the realization of brain-inspired
hardware, apt to tackle computation of unstructured data more efficiently than currently done
with standard computational units. Oscillatory neural networks are know ...
A cardiovascular monitoring system for measuring at least cardiac output comprises an implantable unit (2) configured for placement in a section of artery of a patient and a portable external unit (1) configured for mounting against or close to a patient's ...
Hot exciton materials have the potential to improve the quantum efficiency of organic light-emitting diodes (OLEDs) by promoting high reversed intersystem crossing (hRISC) between a high-lying triplet (T-n, n >= 2) and a radiative singlet (S-m). In recent ...
The recent trend of an increasing share of renewable energy sources in modern power systems, aswell as the integration of power electronics equipment, is shaping the requirements for stable gridinfrastructure. These requirements mainly come from the stabil ...
