‘Smart plastic’ material is step forward toward soft, flexible robotics and electronics

Posted by in categories: robotics/AI, wearables

Inspired by living things from trees to shellfish, researchers at The University of Texas at Austin set out to create a plastic much like many life forms that are hard and rigid in some places and soft and stretchy in others. Their success—a first, using only light and a catalyst to change properties such as hardness and elasticity in molecules of the same type—has brought about a new material that is 10 times as tough as natural rubber and could lead to more flexible electronics and robotics.

The findings are published today in the journal Science.

Regeneration, Intelligence in Life & Memory — Dr Michael Levin

Posted by in categories: biotech/medical, education, ethics, evolution, life extension, wearables

What is limb regeneration and what species possess it? How is it achieved? What does this tell us about intelligence in biological systems and how could this information be exploited to develop human therapeutics? Well, in this video, we discuss many of these topics with Dr Michael Levin, Principal Investigator at Tufts University, whose lab studies anatomical and behavioural decision-making at multiple scales of biological, artificial, and hybrid systems.

Disposable electronics on a simple sheet of paper

Posted by in categories: biotech/medical, mobile phones, wearables

Discarded electronic devices, such as cell phones, are a fast-growing source of waste. One way to mitigate the problem could be to use components that are made with renewable resources and that are easy to dispose of responsibly. Now, researchers reporting in ACS Applied Materials & Interfaces have created a prototype circuit board that is made of a sheet paper with fully integrated electrical components, and that can be burned or left to degrade.

Most small electronic devices contain that are made from glass fibers, resins and metal wiring. These boards are not easy to recycle and are relatively bulky, making them undesirable for use in point-of-care , environmental monitors or personal wearable devices.

One alternative is to use paper-based circuit boards, which should be easier to dispose of, less expensive and more flexible. However, current options require specialized paper, or they simply have traditional metal circuitry components mounted onto a sheet of paper. Instead, Choi and colleagues wanted to develop circuitry that would be simple to manufacture and that had all the electronic components fully integrated into the sheet.

Stretchy, Wearable Synaptic Transistor Turns Robotics Smarter

Posted by in categories: biotech/medical, robotics/AI, wearables

A team of Penn State engineers has created a stretchy, wearable synaptic transistor that could turn robotics and wearable devices smarter. The device developed by the team works like neurons in the brain, sending signals to some cells and inhibiting others to enhance and weaken the devices’ memories.

The research was led by Cunjiang Yu, Dorothy Quiggle Career Development Associate Professor of Engineering Science and Mechanics and associate professor of biomedical engineering and of materials science and engineering.

The research was published in Nature Electronics.

Stretchy, bio-inspired synaptic transistor can enhance or weaken device memories

Posted by in categories: biotech/medical, robotics/AI, wearables

Robotics and wearable devices might soon get a little smarter with the addition of a stretchy, wearable synaptic transistor developed by Penn State engineers. The device works like neurons in the brain to send signals to some cells and inhibit others in order to enhance and weaken the devices’ memories.

Led by Cunjiang Yu, Dorothy Quiggle Career Development Associate Professor of Engineering Science and Mechanics and associate professor of biomedical engineering and of and engineering, the team designed the synaptic transistor to be integrated in robots or wearables and use to optimize functions. The details were published Sept. 29 in Nature Electronics.

“Mirroring the human brain, robots and using the synaptic transistor can use its to ‘learn’ and adapt their behaviors,” Yu said. “For example, if we burn our hand on a stove, it hurts, and we know to avoid touching it next time. The same results will be possible for devices that use the synaptic transistor, as the artificial intelligence is able to ‘learn’ and adapt to its environment.”

Forget Silicon. This Computer Is Made of Fabric

Posted by in categories: robotics/AI, wearables

The existing jacket can perform one logical operation per second, compared to the more than a billion operations per second typical of a home computer, says Preston. In practice, this means the jacket can only execute short command sequences. Due to the speed of the logic, along with some other engineering challenges, Zhang says he thinks it’ll take five to 10 years for these textile-based robots to reach commercial maturity.

In the future, Preston’s team plans to do away with the carbon dioxide canister, which is impractical. (You have to refill it like you would a SodaStream.) Instead, his team wants to just use ambient air to pump up the jacket. As a separate project, the team has already developed a foam insole for a shoe that pumps the surrounding air into a bladder worn around the waist when the wearer takes a step. They plan to integrate a similar design into the jacket.

Preston also envisions clothing that senses and responds to the wearer’s needs. For example, a sensor on a future garment could detect when the wearer is beginning to lift their arm and inflate without any button-pressing. “Based on some stimulus from the environment and the current state, the logic system can allow the wearable robot to choose what to do,” he says. We’ll be waiting for this fashion trend to blow up.

Wearable sensors styled into t-shirts and face masks

Posted by in categories: biotech/medical, health, wearables

Imperial researchers have embedded new low-cost sensors that monitor breathing, heart rate, and ammonia into t-shirts and face masks.

Potential applications range from monitoring exercise, sleep, and stress to diagnosing and monitoring disease through breath and vital signs.

Spun from a new Imperial-developed cotton-based conductive called PECOTEX, the sensors cost little to manufacture. Just $0.15 produces a meter of thread to seamlessly integrate more than ten sensors into clothing, and PECOTEX is compatible with industry-standard computerized embroidery machines.

A WiFi Deauthentication Project in a Sleek Package

Posted by in categories: education, internet, security, wearables

Wearable tech has seen an explosion of creativity and applications in the last decade; especially with circuit components getting smaller and cheaper, and batteries getting better and better. Whereas taking phone calls on your wrist was impressive just a few years ago, now, you can experiment with deauthentication attacks on WiFi networks just from this watch: the DSTIKE Deauther Watch SE.

Based on the ESP8266 WiFi microcontroller, this watch is the latest generation of a project to give you a wearable interface for pen testing local WiFi networks. The watch only works on 2.4GHz networks, due to the restrictions of the ESP8266. It comes pre-flashed with the latest ESP8266 Deauther firmware, which is an open-source project! The watch supports four main functions: a deauther attack, which disconnects all local 2.4GHz networks; deauther beacon, used for creating fake networks; deauther probe, to confuse any nearby WiFi trackers; and packet monitoring, which lets you display local WiFi traffic. As you can see, there’s a lot to appreciate in this slick and discreet package.

This watch (and its prior iterations) are made and sold by Travis Lin. Much like the seller emphasizes on the product page, this device is meant for educational purposes, and should be only tested on devices and networks you own. But if this has your curiosity piqued, put on your red hat and check out the wearable devices and other security goodies they have for sale!
