Boost efficiency and stability of optical rectennas
The research team that announced the first optical rectenna in 2015 is now reporting a two-fold efficiency improvement in the devices — and a switch to air-stable diode materials. The improvements could allow the rectennas – which convert electromagnetic fields at optical frequencies directly to electrical current – to operate low-power devices such as temperature sensors.
Self-organising organic molecules form complex materials
An international team of researchers lead by the Technical University of Munich (TUM) has discovered a reaction path that produces exotic layers with semiregular structures. These kinds of materials are interesting because they frequently possess extraordinary properties. In the process, simple organic molecules are converted to larger units which form the complex, semiregular patterns.
The quantum leap with EMF Motor
Cast your mind back 20 years ago, an engineer co-developed a new concept of electric motor, which was supposed to be far superior to the traditional motor. The synchronous torque motor should achieve a much higher torque at low speeds and therefore be more efficient than traditional motors.
Designing metamaterials with quantum mechanics
Engineers at Caltech and ETHZürich in Switzerland have created a method to systematically design metamaterials using principles of quantum mechanics.Their work could pave the way for wider use of metamaterials in more mainstream applications by creating a purpose-driven framework for their design.Metamaterials are engineered materials that exploit the geometry of their internal structure to manipulate incoming waves.
Next-gen flexible robots are as strong as biological muscles
In the basement of the Engineering Center at CU Boulder, a group of researchers is working to create the next generation of robots.But instead of the metallic droids you may be imagining, these robots are made from soft materials that react to applied voltage with a wide range of motions. Such soft robots contain tremendous potential for future applications as they adapt to dynamic environments and are well-suited to closely interact with humans.
Dielectric boosts stability of organic thin-film transistors
A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric and simultaneously protects the organic semiconductor – which had previously been vulnerable to damage from the ambient environment – and enabl...
Grasshoppers inspire health-monitoring electrode
Researchers at ETH Zurich have developed a new type of health-monitoring electrode that exhibits optimum adhesion to skin and can record high quality signals. Two young spin-off founders want to turn it into a marketable product as early as this year.Anyone who has ever had an electrocardiogram – for example, to check their heart fitness – will be familiar with the electrodes that the doctor attaches to the chest.
Anodising centres specialises in automotive applications
Aluminium anodising facility, BCW Treatments opened back in 2015 to provide a full service to companies using the subcontract machining services of BCW Manufacturing Group's machine shops on the same industrial estate as it. Anodising is carried out in a Galvatek automated finishing line supplied by Turbex, which was deemed to be the best all-round package of three alternatives considered. Currently, an average of 2,600 square metres of product p...
Planning entire systems with virtual reality
Schnaithmann implements the demand for support in planning conveyor or assembly systems with the help of virtual reality. Already in the conception phase, the customer can experience his subsequent installation on a holodeck, realistically, and then virtually examine it for ergonomic aspects or maintenance easiness. The use of virtual reality technology also promises advantages when training employees.
Software package provides enhanced speech intelligibility
A new software suite of advanced voice input processing algorithms has been introduced by CEVA. ClearVox is aimed at enhancing speech intelligibility and voice clarity for voice-enabled devices and is licensed exclusively for the CEVA-TeakLite-4 and CEVA-X2 audio/voice DSPs.As voice becomes the primary user interface for cloud-based assistant services, a clean voice signal in any given environment is mandatory to ensure accuracy and intelligibili...
