Printed, Flexible and Organic Electronics

Printed, Flexible and Organic Electronics

Printed Electronics, being thin film silicon or inorganic or organic semiconductors, can be used to form Thin Film Transistor Circuits (TFTCs), such as replacing the functionality of simple silicon chips. TFTCs also employ thin film conductors and dielectrics and the ultimate objective is to make many different components at the same time - such as displays, batteries, sensors, microphones etc using the same materials or at least the same deposition techniques thus saving cost and improving reliability. Some TFTCs will be capable of covering large areas to affordably form electronic billboards, smart shelves and so on. They will be lightweight, rugged and mechanically flexible. Often they will be made by rapid, high-volume reel-to-reel processing even forming a part of regular printing processes for graphics. These circuits will be cheap enough to permit electronics where envisaged silicon chips are always or almost always too expensive, where multiple components and needed, and where silicon is impracticle (e.g. not flexible, brittle, thick etc).

Improved Heat Dissipation in Thin Film Devices

The last few decades have witnessed a tremendous advance in electronics technology, with the development of devices that are thinner, lightweight, flexible, and robust. However, as the devices get thinner so does the space for accommodating the internal working components. This has created an issue of improper heat dissipation in thin-film devices, since conventional heat sink materials are bulky and cannot be integrated into them.

Thin Film Technologies for the Energy Transition

Glass facades characterize modern architecture. While solar radiation serves to support heating in winter, the building interior heats up in summer and requires active cooling. Smart windows can regulate the solar radiation according to the weather situation - a forward-looking solution in times of energy saving. Researchers have now succeeded in producing the world's first thermochromic layer on ultra-thin glass in a roll-to-roll process. These results will make mechanical blinds superfluous in the future and at the same time reduce the cooling and heating energy requirements of a building.

European-Sponsored Project to Increase Sustainability of Electronics

TNO at Holst Centre in Eindhoven hosted the kick-off of the ECOTRON project, which has been set up to reach a sustainable electronics production process through hybrid printed electronics. In short, ECOTRON aims to create more sustainable electronics by using printing and dismantling techniques that allow low-energy production processes and a circular build-up of materials that are potentially of 'renewable' or compostable origin.

SAFI-Tech

SAFI-Tech is an American company based in Iowa and was founded in 2016. SAFI-Tech has developed an innovative approach to low temperature soldering. This involves confining super-cooled liquid solder within a primarily oxide shell, which enables it to flow at ambient temperature when the shell is broken. This is especially useful for soldering temperature sensitive components.

Sensing Pressure Using Paper

Several industrial, automotive, and healthcare applications rely on accurate and precise measurement of pressure. Flexible and wearable pressure sensors are typically fabricated using petroleum-based polymers. The solid waste generated from using such non-biodegradable plastics is harmful for the environment. To avoid this issue, researchers have now fabricated pressure sensors that use paper as the medium.

LG Breaks Record for 6G Data Transmission

LG Electronics has successfully tested the wireless transmission and reception of 6G terahertz data - at a frequency range of 155 to 175 GHz - over a distance of 320 meters outdoors. The milestone represents a significant step toward commercializing 6G THz in both indoor and outdoor urban areas since the reference cell coverage of base stations for urban macro cells is a distance of approximately 250 meters outdoors. It is also a major jump from August last year, when LG proved it could transfer 6G THz data over a distance of 100 meters outdoors.
