When we think about clothing, we usually think of it as something we wear to cover our body, convey our style and protect us from the environment. What if the cloth changes its visual appearance when you stretch your hand?... such mechanoresponsive material has enormous potential in a large range of transformative applications in the beauty and health industry.
Cholesteric Liquid Crystal Elastomer (CLCE) is a structurally coloured polymer system capable of changing its colour by mechanical deformation, due to the coupling of colour of helically aligned liquid crystal molecules and the viscoelasticity of rubber. Prof. Jan Lagerwall, Dr. Yong Geng and Rijeesh Kizhakidathazhath at the University of Luxembourg created colour-changing CLCE fibres that can be easily sewn into the fabric.

Electronics circuitry is hard and rigid. We are not. And so a sea change is required if we want to make wearables that actually fit the human form.
Wrist-worn wearables only work as well as they do because there's a thin layer of relatively static human putty above our bones in this area. Try to produce a sensor for the neck or joints and you'll discover that today's wearables, small computers strapped onto pliant flesh, aren't up to the job.
Several stretchable solutions are in the works, though. Here are some of the most exciting and innovative projects to look out for. Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/21st-century-innovative-technologies-and-developments/?&tag=wearables

New conductive MXene nanocoating may unlock biometric and wearable technology of the future
(Nanowerk News) A team of researchers from the College of Engineering at Texas A&M University have developed a mechanically robust conductive coating that can maintain performance under heavy stretching and bending.
Stretchable, bendable and foldable electronics are crucial for the development of emerging technologies like adaptive displays, artificial skin, and biometric and wearable devices. This presents a unique challenge of balancing electronic performance and mechanical flexibility. The difficulty lies in finding a material that can withstand a wide array of deformations, like stretching, bending and twisting, all while maintaining electrical conductivity.
Adding to the challenge is the need for this conductivity to be engineered into a variety of different surfaces, such as cloth, fiber, glass or plastic. Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/21st-century-innovative-technologies-and-developments/?&tag=Nano

Eine smarte Brille mit leichtem Gestell, die kaum auffällt und Informationen direkt ins Auge überträgt: Der Chiphersteller präsentiert erstmals sein Projekt "Vaunt", das bald für Entwickler zugänglich sein soll.
Intel arbeitet an einer smarten Datenbrille, die kaum von einem herkömmlichen Brillengestell zu unterscheiden ist. Sie soll lediglich 50 Gramm wiegen und den Benutzer nicht ablenken, wie The Verge berichtet. Die Technik samt Akku befindet sich in den Ohrbügeln. Anders als bei Googles viel beachtetem (und klobigem) Modell "Glass" projiziert die "Vaunt" genannte Datenbrille Bildinformationen nicht auf das Brillenglas, sondern direkt auf die Netzhaut. Damit ist für andere Personen auch nicht erkennbar, ob der Brillenträger gerade Informationen zu sehen bekommt.

Eine neue Art von flexiblen Mikro-Superkondensatoren entwickelt von Forschern der Nanyang Technological University in Singapur scheint wie gemacht für den Einsatz in Wearables und eignet sich noch für viele andere Anwendungen wie z. B. einem Smartshirt, das Smartphones aufladen kann.
Diese Miniaturausgabe eines Superkondensators nutzt Strukturen von Mikro-Ribbons aus Graphen und ist so gebaut, dass die Anspannung an den Elektrodenfingern reduziert ist. Das verhindert Brüche und Abrisse von Elektrodenmaterial und hält die Elektrodenfinger auf relativ konstantem Abstand.
Diese Strukturen begegnen den Problemen klassische Energielieferanten wie Batterien, die dick und steif sind und sich daher nicht gut für kleine, verformbare Wearables eignen.
Graphen ist für seine Leitfähigkeit bekannt sowie für seine Zugfestigkeit und Kleinheit, aber nicht für seine Elastizität. Um Letzteres zu ändern, haben sich die Forscher für eine wellenartige Mikrostruktur entschieden und dieses Prinzip auf Graphen bzw. die Mikro-Ribbons übertragen. Diese wurden dann in den pyramidenförmigen Erhebungen eines elastischen Polymer-Chips platziert und bilden so eine wellenförmige Struktur. Dieses Kirigami-Prinzip macht den Supercap dann um 500 % flexibler, ohne die elektrochemischen Eigenschaften zu beeinträchtigen.

A new stick-on wearable sensor uses the symphony of internal rumblings, whooshing, gurglings, and cracklings to help doctors diagnose different conditions. And this souped-up, miniaturized stethoscope could one day be a way for clinicians to continuously monitor patients outside of the clinic. So far it’s been tested on chicken breasts and a very small group of people. IT STICKS TO THE SKIN LIKE A TEMPORARY TATTOO This wearable, smaller than a penny, can hear the beat of your heart, the sound of your voice, and even the whirr of an implantable heart pump, according to a paper published today in the journal Science Advances.

Apple is working on wearable digital glasses that would connect wirelessly to the iPhone and show content in the wearer’s field of vision, according to a news report.
The iPhone maker has indicated previously its interest in augmented reality. Unlike the simulated world of virtual reality, AR supplements with images and information the user’s normal view of the world.
“We are high on AR for the long run. We think there are great things for customers and a great commercial opportunity,” Apple CEO Tim Cook said in an earnings call in July, talking about the need for Apple’s devices to work with other developers’ products, such as the successful Pokémon Go game.
The company has also hired VR and AR experts and made some acquisitions that could help it meet its AR goals. Apple has discussed the glasses project with potential suppliers, reported Bloomberg on Monday, citing people familiar with those discussions.

Developers and businesses can now buy Google's Glass Enterprise Edition 2 directly from a handful of hardware resellers, Google announced Tuesday. Previously, interested enterprise customers had to work with Google partners to build custom software for the augmented reality glasses that fit their specific needs.
After Google Glass failed to take off as a consumer product, Google revived the AR glasses for the enterprise in 2017. It launched the second edition in May of last year. They're used in a variety of sectors, including logistics, manufacturing and field services
"Since Glass Enterprise Edition 2 launched last May, we've seen strong demand from developers and businesses who are interested in building new, helpful enterprise solutions for Glass," Google's Jay Kothari wrote in a blog post.
The glasses are built on Android, enabling businesses to integrate the services and APIs they already use. Google is also sharing new open source applications and code samples to help developers build applications for the glasses.

Pour que les avantages de l'Internet des Objets soit réels, le nombre d'objets connectés doit croître encore. Et la limite de l'expansion du nombre d'objets connectés repose à ce jour sur le coût, la puissance et la taille de l'électronique embarquée.
Des chercheurs de l'Université Purdue et de l'Université de Virginie aux Etats-Unis viennent de proposer une technique qui permet de baisser ces coûts. Pour ce faire, ils ont développé une nouvelle méthode de fabrication de circuits ultra-minces destiné à être collé sur des objets jusqu'alors non-connectés.
Un processus qui élimine non seulement un certain nombre d'étapes de fabrication, réduisant ainsi le coût, mais pourrait faire en sorte que presque n'importe quel objet peut agir comme un capteur. Bien sûr, les matériaux électroniques qui peuvent être disposés et fonctionner sur un film plastique ne sont pas nouveaux. Mais ce procédé d'impression par transfert, utilisant des combinaisons de nanomatériaux actifs, constitue un pas en avant, tant sur le plan technologique qu'écologique.

This seizure-spotting smart watch has won FDA approval
Startup Empatica says its Embrace smart watch is now approved by the US Food and Drug Administration as a medical device—a rare designation for a wearable.
Winning approval: The $249 watch detects when a wearer is having a convulsive seizure and lets family members know via a smartphone app. In a 135-patient trial as part of the FDA approval, epilepsy patients suffered 40 seizures, and the watch’s algorithm spotted them all.
Why it matters: There are 3.4 million people in the US with epilepsy. Worldwide, the figure is roughly 50 million. Keeping track of when seizures happen can help get patients medical attention and aid doctors in monitoring their condition over time.
What it means for wearables: The approval allows the firm to make medical claims about the device, and could enable people with epilepsy to have insurance pay for it. It may also encourage doctors and hospitals to use such devices, says Rosalind Picard, Empatica’s cofounder and chief scientist.

Force, leveraging the expertise and insights of academia has led to advances in materials development and processing destined to be a game changer for the future fight.
A collaboration between scientists at the Air Force Research Laboratory and Harvard University’s Wyss Institute for Biologically Inspired Engineering has resulted in a new method for digital design and printing of stretchable, flexible electronics. The process, called Hybrid 3-D printing, uses additive manufacturing to integrate soft, conductive inks with a material substrate to create stretchable, wearable electronic devices.
“This is the first time a 3-D printer has been shown, in a single process, to print stretchable sensors with integrated microelectronic components,” said Dr. Dan Berrigan, a research scientist at the AFRL Materials and Manufacturing Directorate. “Starting from nothing, the printer builds an entire stretchable circuit that blends the mechanical durability of printed components with the robust performance of off-the-shelf electronics.”
In this demonstration, a 3-D printer was used to print conductive traces of flexible, silver-infused thermoplastic polyurethane. A pick-and-place method was then used to set microcontroller chips and LED lights into the flexible substrate, augmented by an empty printer nozzle and vacuum system to create the hybrid system.
When tested, the additively manufactured, hybrid-electronic devices were able to maintain function even after being stretched by more than 30 percent from original size.
“This has a lot of potential for Air Force applications, particularly in the areas of rapid prototyping, wearable electronics, sensors and human performance monitoring,” said Berrigan. “Skin-worn electronics have the potential to provide feedback on movement, body temperature, fatigue, hydration and other metrics crucial to understanding Airmen performance. However, while skin is inherently soft and stretchable, electronics and sensors are not.” Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/21st-century-innovative-technologies-and-developments/?&tag=wearables https://www.scoop.it/t/21st-century-innovative-technologies-and-developments/?&tag=Electronics

At the Waseda University in Japan, researchers have come up with a new, cheaper way of producing electronic devices that are flexible, elastic, and adhere to the skin. This development may help body monitoring electronic skin patches that interface with smartphone apps to become commonly used in medicine and by consumers.
The technology relies on elastomeric films only 1 μm thick that can safely contain electronic components sandwiched between them. An inkjet printer is used to put down lines of silver for wiring the components together. Importantly, there’s no soldering or gluing involved, which allows for a thinner final product that is highly flexible without fear of damage to the electrical connections.

We've all been struck by a jolt of inspiration at the most inopportune moment, only to have the brilliant idea slip away before it can be jotted down. A new voice-recording wearable could ensure that never happens again.
Launched on Kickstarter earlier this month, Senstone is a compact brooch-sized device designed to capture your spur-of-the-moment thoughts at the tap of a button, transferring them to a companion app on your smartphone. But it doesn't stop there: the device's real potential is in its purported automatic-transcription feature, which takes your voice memos and turn them into text you can edit and share.

With the advent of the Internet of Things (IoT) era, strong demand has grown for wearable and transparent displays that can be applied to various fields such as augmented reality (AR) and skin-like thin flexible devices. However, previous flexible transparent displays have posed real challenges to overcome, which are, among others, poor transparency and low electrical performance. To improve the transparency and performance, past research efforts have tried to use inorganic-based electronics, but the fundamental thermal instabilities of plastic substrates have hampered the high temperature process, an essential step necessary for the fabrication of high performance electronic devices.
