Combining integrated photonics and MEMS technology, scientists from EPFL and Purdue University demonstrate monolithic piezoelectric control of integrated optical frequency combs with bulk acoustic waves. The technology opens up integrated ultrafast acousto-optic modulation for demanding applications.

For a long time, something important has been neglected in electronics: If you want to make electronic components smaller and smaller, you also need the right insulator materials. Ever smaller and ever more compact - this is the direction in which computer chips are developing, driven by industry. This is why so-called 2D materials are considered to be the great hope: they are as thin as a material can possibly be, in extreme cases they consist of only one single layer of atoms.

MIT engineers develop a hybrid process that connects photonics with "artificial atoms," to produce the largest quantum chip of its type. MIT researchers have developed a process to manufacture and integrate "artificial atoms," created by atomic-scale defects in microscopically thin slices of diamond, with photonic circuitry, producing the largest quantum chip of its type.

Researchers have built an ultrafast chip that can speed up data transmission in fibre optic networks. The chip combines several innovations at the same time and, given the growing demand for streaming and online services, represents a significant development.

Researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range - and they are unrivalled in terms of weight. Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals.

UCLA bioengineers have designed a glove-like device that can translate American Sign Language into English speech in real time though a smartphone app. The ir research is published Electronics. "Our hope is that this opens up an easy way for people who use sign language to communicate directly with non-signers without needing someone else to translate for them," said Jun Chen, an assistant professor of bioengineering at the UCLA Samueli School of Engineering and the principal investigator on the research.

Researchers have provided the first theoretical explanation for how electrical current is conducted in semiconductors made of nanocrystals. In the future, this could lead to the development of new sensors, lasers or LEDs for TV screens. A few years ago, we were introduced to TV screens featuring QLED technology that produces brilliant colours.

A new technique that synchronises the clocks of computers in under a billionth of a second can eliminate one of the hurdles for the deployment of all-optical networks, potentially leading to more efficient data centres, according to a new study led by UCL and Microsoft. Data centres, comprising tens or hundreds of thousands connected servers, are the underlying technology empowering everything we do online, from storing films and photos to serving up webpages and online services.

In the not-too-distant future, flexible electronics will open the door to new products like foldable phones, tablets that can be rolled, paper-thin displays and wearable sensors that monitor health data. Developing these new bendy products, however, means using materials like new plastics and thin films to replace the rigid circuit boards and bulky electronic components that currently occupy the interiors of cell phones and other gadgets.

Organizations like the World Bank imply that equality is an important aspect of their goals for expanding electricity access in developing countries. Yet few studies have actually addressed how to ensure equality in developing areas like sub-Saharan Africa, and many have even used methods that further inequality.

That visible light holds the character of a wave can be demonstrated in simple optics experiments, or directly witnessed when rainbows appear in the sky. Although the subtle laws of quantum mechanics, that is, wave mechanics, ultimately govern all the processes of electron transportelectrons in solids, their wave-like nature of the electrons is not often apparent to the casual observer.

Data-Transmission Rate of 7. Gbps Positions LiFi as Possible Replacement for WiFi with Further R&D and Industrial Standardization to Ensure Interoperability of Systems capability of 5G. GRENOBLE, France - June 11, 2020 CEA-Leti today announced its researchers have broken the throughput world record of 5.

EPFL researchers have developed electronic fibers that, when embedded in textiles, can collect a wealth of information about our bodies by measuring subtle and complex fabrics deformations. Their technology relies on transmission line theory and offers a host of applications, such as in health care and robotics.

A team of researchers has succeeded in using an electric current to directly control gene expression for the first time. Their work provides the basis for medical implants that can be switched on and off using electronic devices outside the body. This is how it works. A device containing insulin-producing cells and an electronic control unit is implanted in the body of a diabetic.

By Birgit Baustädter Electronics-based systems have long since found their way into our everyday lives. Consciously in the form of new technical gadgets and unconsciously in the form of embedded systems. It is therefore impossible to imagine our familiar life without electronics-based systems. But, and here researchers are in agreement, they will continue to shape our environment in the future as the basis for many innovative developments.

Stimulating the vagus nerve in the ear can help relieving chronic pain. TU Wien and MedUni Vienna have developed novel, sophisticated methods for electric stimulation of the vagus nerve. The vagus nerve plays an important role in our body. It consists of various fibres, some of which connect to the internal organs, but the vagus nerve can also be found in the ear.

Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars, robots or even drones. The technology could be scaled up to power electric cars as they drive over highways, robots on factory floors and drones hovering over rooftops. Stanford engineers have taken a big step toward making it practical for electric cars to recharge as they speed along futuristic highways built to "refuel" vehicles wirelessly.

Leaky waveguide could help devices find one another on future, high-speed data networks By Kevin Stacey Special to Rice News When you open a laptop, a router can quickly locate it and connect it to the local Wi-Fi network. That ability, known as link discovery, is a basic element of any wireless network, and now a team of engineering researchers from Rice University and Brown University has developed a way to do that with terahertz radiation, the high-frequency waves that could one day make for ultrafast wireless data transmission.

MIT researchers have developed a way to incorporate electronic sensors into stretchy fabrics, allowing them to create shirts or other garments that could be used to monitor vital signs such as temperature, respiration, and heart rate. The sensor-embedded garments, which are machine washable, can be customized to fit close to the body of the person wearing them.

Using integrated photonic chips fabricated at EPFL, scientists have demonstrated laser-based microwave generators. These microwave signals, as well as their optical carriers, could be used in radars, satellite communications and future 5G wireless networks. In our information society, the synthesis, distribution, and processing of radio and microwave signals are ubiquitous in wireless networks, telecommunications, and radars.
