Stanford Researchers Create Organic Electronic Components That Dissolve Into The Body

From Scientists unveil ultra-thin electronics that can dissolve into the body

the team’s inventions include a biodegradable semi-conductive polymer, disintegrable and flexible electronic circuits, and a biodegradable substrate material for mounting these electrical components onto.

Totally flexible and biocompatible, the ultra-thin film substrate allows the components to be mounted onto both rough and smooth surfaces.

All together, the components can be used to create biocompatible, ultra-thin, lightweight and low-cost electronics for applications as diverse as wearable electronics to large-scale environmental surveys.

Maybe this is one of the many approaches we’ll use for biohacking or as wearable technology in the future.

SetPoint Medical Working On a Device That Emits Electrical Pulses To Treat Arthritis

From The shock tactics set to shake up immunology : Nature

The human vagus nerve contains around 100,000 individual nerve fibres, which branch out to reach various organs. But the amount of electricity needed to trigger neural activity can vary from fibre to fibre by as much as 50-fold.

Yaakov Levine, a former graduate student of Tracey’s, has worked out that the nerve fibres involved in reducing inflammation have a low activation threshold. They can be turned on with as little as 250-millionths of an amp — one-eighth the amount often used to suppress seizures. And although people treated for seizures require up to several hours of stimulation per day, animal experiments have suggested that a single, brief shock could control inflammation for a long time10. Macrophages hit by acetylcholine are unable to produce TNF-α for up to 24 hours, says Levine, who now works in Manhasset at SetPoint Medical, a company established to commercialize vagus-nerve stimulation as a medical treatment.

By 2011, SetPoint was ready to try the technique in humans, thanks to animal studies and Levine’s optimization efforts. That first trial was overseen by Paul-Peter Tak, a rheumatologist at the University of Amsterdam and at the UK-based pharmaceutical company GlaxoSmithKline. Over the course of several years, 18 people with rheumatoid arthritis have been implanted with stimulators, including Katrin.

For the images of the actual device, check Core77. They also have implantable bioelectronic devices.

ReVoice Develops a Glove to Translate Sign Language Into Speech

From This Glove Translates Sign Language Into Speech

Ayoub, who is currently a Ph.D. researcher at Goldsmiths College in London, designed the glove for anyone who relies on sign language to communicate, from deaf people to children who have non-verbal autism and communicate through gestures. To use it, you simply put the glove on and start signing. The glove translates the signs in real time into sentences that appear on a small screen on the wrist, which can then be read out loud using a small speaker.

noonee Develops A Wearable Chair

From A Wearable Chair Designed to Improve Working Conditions that Involve Manual Labor – Core77

The Chairless Chair® is a flexible wearable ergonomic sitting support designed by Sapettiand produced by the Swiss-based company noonee.

The main application of the Chairless Chair® is for manufacturing companies, where workers are required to stand for long periods of time and traditional sitting methods are not suitable, leading to obstacles in the work area. While wearing the Chairless Chair, users walk together with sitting support without obstructing the work space. The position also avoids strenuous postures such as bending, squatting or crouching.

I wonder if the device impedes the act of running, in case of emergency.

Bionik Laboratories Explores Voice-Controlled Exoskeleton

From This exoskeleton can be controlled using Amazon’s Alexa – The Verge

Bionik Laboratories says it’s the first to add the digital assistant to a powered exoskeleton. The company has integrated Alexa with its lower-body Arke exoskeleton, allowing users to give voice commands like “Alexa, I’m ready to stand” or “Alexa, take a step.”

Movement of the Arke, which is currently in clinical development, is usually controlled by an app on a tablet or by reacting automatically to users’ movements. Sensors in the exoskeleton detect when the wearer shifts their weight, activating the motors in the backpack that help the individual move. For Bionik, adding Alexa can help individuals going through rehabilitation get familiar with these actions.

Voice-controlled exoskeleton is an interesting way to overcome the complexity of creating sophisticated brain-machine interfaces, but current technology has a lot of limitations. For example, Alexa doesn’t have yet voice fingerprinting, so anybody in the room could, maliciously or not, utter a command on behalf of the user and harm that person with an undesired exoskeleton movement at the wrong time.

Nonetheless, these are valuable baby steps. If you are interested in Bionik Laboratories, you can see a lot more in their on-stage presentation at IBM Insight conference in 2015.

When you speak in English, there’s a short delay and then your interlocutor hears it in Mandarin Chinese (or whatever other languages are added later). They respond in Chinese, and you hear it in English — it’s really that simple.

The main issue I had was with the latency, which left Wells and I staring at each other silently for a three count while the app did its work. But the version I used wasn’t optimized for latency, and the team is hard at work reducing it.

“We’re trying to shorten the latency to 1-3 seconds, which needs lots of work in optimization of the whole process of data transmission between the earphones, app and server,”

Chinese researchers develop colour-shifting electronic skin

From Colour-shifting electronic skin could have wearable tech and prosthetic uses – IOP Publishing

researchers in China have developed a new type of user-interactive electronic skin, with a colour change perceptible to the human eye, and achieved with a much-reduced level of strain. Their results could have applications in robotics, prosthetics and wearable technology.

…the study from Tsinghua University in Beijing, employed flexible electronics made from graphene, in the form of a highly-sensitive resistive strain sensor, combined with a stretchable organic electrochromic device.

Orii builds a smart ring that turns a fingertip into an earpiece

From Orii smart ring turns your fingertip into a Bluetooth earpiece

you wear the ring on your index finger, and when it vibrates with an incoming call, simply lift your hand up, touch your fingertip on a sweet spot just before your ear, then chat away. An earlier crowdfunding project, the Sgnl smart strap (formerly TipTalk) by Korea’s Innomdle Lab, had the same idea, but it has yet to ship to backers long after its February target date this year.

The Orii is essentially an aluminum ring melded to a small package containing all the electronics. The main body on the latest working prototype came in at roughly 30 mm long, 20 mm wide and 12 mm thick.

Inflammation-free, gas-permeable, lightweight, stretchable on-skin electronics with nanomeshes

From Inflammation-free, gas-permeable, lightweight, stretchable on-skin electronics with nanomeshes : Nature Nanotechnology : Nature Research

Thin-film electronic devices can be integrated with skin for health monitoring and/or for interfacing with machines. Minimal invasiveness is highly desirable when applying wearable electronics directly onto human skin. However, manufacturing such on-skin electronics on planar substrates results in limited gas permeability. Therefore, it is necessary to systematically investigate their long-term physiological and psychological effects.

As a demonstration of substrate-free electronics, here we show the successful fabrication of inflammation-free, highly gas-permeable, ultrathin, lightweight and stretchable sensors that can be directly laminated onto human skin for long periods of time, realized with a conductive nanomesh structure. A one-week skin patch test revealed that the risk of inflammation caused by on-skin sensors can be significantly suppressed by using the nanomesh sensors.

Furthermore, a wireless system that can detect touch, temperature and pressure is successfully demonstrated using a nanomesh with excellent mechanical durability. In addition, electromyogram recordings were successfully taken with minimal discomfort to the user.

ReWalk Robotics makes progress with its soft exoskeleton

From ReWalk Robotics shows off a soft exosuit designed to bring mobility to stroke patients | TechCrunch

The version on display is still a prototype, but all of the functionality is in place, using a motorized pulley system to bring mobility to legs impacted by stroke.

The device, now known as the Restore soft-suit, relies on a motor built into a waistband that controls a pair of cables that operate similarly to bicycle brakes, lifting a footplate in the shoe and moving the whole leg in the process. The unaffected leg, meanwhile, has sensors that measure the wearer’s gait while walking, syncing up the two legs’ movement.

Progress in Smart Contact Lenses

From Smart Contact Lenses – How Far Away Are They? – Nanalyze

The idea of smart contact lenses isn’t as far away as you might think. The first problem that crops up is how exactly do we power the electronics in a set of “smart” contact lenses. As it turns out, we can use the energy of motion or kinetic energy. Every time the eye blinks, we get some power. Now that we have the power problem solved, there are at least several applications we can think of in order of easiest first:

  • Level 1 – Multifocal contact lenses like these from Visioneering Technologies, Inc. (VTI) or curing color blindness like these smart contact lenses called Colormax
  • Level 2 – Gathering information from your body – like glucose monitoring for diabetics
  • Level 3 – Augmenting your vision with digital overlay
  • Level 4 – Complete virtual reality (not sure if this is possible based on the eye symmetry but we can dream a dream)

So when we ask the question “how far away are we from having smart contact lenses” the answer isn’t that simple. The first level we have already achieved.

Scientists make a wearable substance that sticks to human skin without irritation and can record data

From This super-stretchy wearable feels like a second skin and can record data – The Verge

scientists have created a super-thin wearable that can record data through skin. That would make this wearable, which looks like a stylish gold tattoo, ideal for long-term medical monitoring — it’s already so comfortable that people forgot they were wearing it.

Most skin-based interfaces consist of electronics embedded in a substance, like plastic, that is then stuck onto the skin. Problem is, the plastic is often rigid or it doesn’t let you move and sweat. In a paper published today in the journal Nature Nanotechnology, scientists used a material that dissolves under water, leaving the electronic part directly on the skin and comfortable to bend and wear.

Google Glass Enterprise Edition gets adopted where it always meant to be

From Google Glass 2.0 Is a Startling Second Act | WIRED

Companies testing EE—including giants like GE, Boeing, DHL, and Volkswagen—have measured huge gains in productivity and noticeable improvements in quality. What started as pilot projects are now morphing into plans for widespread adoption in these corporations. Other businesses, like medical practices, are introducing Enterprise Edition in their workplaces to transform previously cumbersome tasks.

and

For starters, it makes the technology completely accessible for those who wear prescription lenses. The camera button, which sits at the hinge of the frame, does double duty as a release switch to remove the electronics part of unit (called the Glass Pod) from the frame. You can then connect it to safety glasses for the factory floor—EE now offers OSHA-certified safety shields—or frames that look like regular eyewear. (A former division of 3M has been manufacturing these specially for Enterprise Edition; if EE catches on, one might expect other frame vendors, from Warby Parker to Ray-Ban, to develop their own versions.)

Other improvements include beefed-up networking—not only faster and more reliable wifi, but also adherence to more rigorous security standards—and a faster processor as well. The battery life has been extended—essential for those who want to work through a complete eight-hour shift without recharging. (More intense usage, like constant streaming, still calls for an external battery.) The camera was upgraded from five megapixels to eight. And for the first time, a red light goes on when video is being recorded.

If Glass EE gains traction, and I believe so if it evolves into a platform for enterprise apps, Google will gain a huge amount of information and experience that can reuse on the AR contact lenses currently in the work.

Earpiece translates in (almost) real-time a conversation in two different languages

From Waverly Labs Pilot Translation Kit Release Date, Price and Specs – CNET

The heart of the process is Waverly’s app, which both and your friend need to download onto your phones (it’s free on both iOS and Android). Then, once you “sync” your conversation through a matching QR code on the app, you’re off and speaking. Press a button on the app and talk into the earpiece’s microphone to record what you want to say. Your voice is then piped through Waverly’s machine translation software which converts it to text on your friend’s app. If he also has his own earpiece, your friend will hear a translated version of what you said, albeit via a computer voice.

Language barrier issues won’t go away completely for years but will be significantly different.

AI and wearables powering the Post-Truth Era

From Anti AI AI — Wearable Artificial Intelligence – DT R&D

Near the end of 2017 we’ll be consuming content synthesised to mimic real people. Leaving us in a sea of disinformation powered by AI and machine learning. The media, giant tech corporations and citizens already struggle to discern fact from fiction. And as this technology is democratised it will be even more prevalent.

Preempting this we prototyped a device worn on the ear and connected to a neural net trained on real and synthetic voices called Anti AI AI. The device notifies the wearer when a synthetic voice is detected and cools the skin using a thermoelectric plate to alert the wearer the voice they are hearing was synthesised: by a cold, lifeless machine.

Mind-blowing.
