Scientists create stretchable battery made entirely out of fabric

A research team led by faculty at Binghamton University, State University of New York has developed an entirely textile-based, bacteria-powered bio-battery that could one day be integrated into wearable electronics.

The team, led by Binghamton University Electrical and Computer Science Assistant Professor Seokheun Choi, created an entirely textile-based biobattery that can produce maximum power similar to that produced by his previous paper-based microbial fuel cells.

Additionally, these textile-based biobatteries exhibit stable electricity-generating capability when tested under repeated stretching and twisting cycles.

3D-printed live bacteria creates world’s first “living tattoo”

A team at MIT has genetically modified bacteria cells and developed a new 3D printing technique to create a “living tattoo” that can respond to a variety of stimuli.

Electronic tattoos and smart ink technologies are showing exciting potential for reframing how we think of wearable sensor devices. While many engineers are experimenting with a variety of responsive materials the MIT team wondered if live cells could be co-opted into a functional use.

The first step was to look at what organic cells could be utilized, and it turned out that the strong cell walls of bacteria were the best target for use as they could survive the force of a 3D printer’s nozzle. Bacteria also proved to be perfectly compatible with the hydrogels needed for accurate 3D printing.

Stretchsense Behind “Disappearable” Zozosuit Smart Garment

New Zealand-built technology enabling an entirely new type of wearable

AUCKLAND, NOVEMBER 22, 2017 — StretchSense Ltd., New Zealand-based manufacturer of wearable sensing systems, today is proud to see the release of ZozoSuit by its client and investor Start Today Co., Ltd., owner of Japan’s largest online fashion retailer. The first consumer-ready wearable product built with StretchSense’s unique sensor technology, the ZozoSuit was developed in close collaboration between the two companies and provides precise measurement of body shape to solve the problem of fit when buying clothes online.

StretchSense’s mission is to go beyond wearables and towards “disappearables” — truly smart garments with unobtrusive sensors and electronics that feel invisible to the wearer. The ZozoSuit is a realization of that vision, blurring the line between clothing and technology with lightweight sensing elements, flexible cabling and miniaturized electronics all fully integrated into a skin-tight garment.

Researchers at the University of Cambridge, working with colleagues in Italy and China, have incorporated washable, stretchable, and breathable integrated electronic circuits into fabric for the first time — opening up new possibilities for smart textiles and wearable textile electronic devices.

The circuits were made with cheap, safe, and environmentally friendly inks, and printed using conventional inkjet-printing techniques.

Nanobots will live in our brains in the 2030s, says Google boss

Ray Kurzweil is director of engineering at Google but he is better known for writing best-selling books outlining the future of artificial intelligence.

He has made 147 predictions on the future of technology including the ubiquity of wearable devices and the move from desktops and laptops to smartphones and tablets. In fact, his prediction rate has been rated 86 per cent accurate.

With this in mind, fans were excited to see Kurzweil answer their questions in a live streaming interview session last week where he elaborated on his predictions.

3D printer makes first wearable ‘battery’

Imagine printing off a wristband that charges your smartphone or electric car with cheap supplies from a local hardware store.

That’s the direction materials research is heading at Brunel University London where scientists have become the first to simply and affordably 3D print a flexible, wearable ‘battery’.

The technique opens the way for novel designs for super-efficient, wearable power for phones, electric cars, medical implants like pacemakers and more.

A sneak peak at radical future user interfaces for phones, computers, and VR

Drawing in air, touchless control of virtual objects, and a modular mobile phone with snap-in sections (for lending to friends, family members, or even strangers) are among the innovative user-interface concepts to be introduced at the 30th ACM User Interface Software and Technology Symposium (UIST 2017) on October 22–25 in Quebec City, Canada.

Here are three concepts to be presented, developed by researchers at Dartmouth College’s human computer interface lab.

Color-changing tattoos monitor blood glucose at a glance

Tattoos are fast becoming more than just a means of self-expression: soon they could be used for more practical applications, like tracking blood alcohol levels or turning the skin into a touchscreen. Now, a team from Harvard and MIT has developed a smart ink that could make for tattoos that monitor biometrics like glucose levels, and change color as a result.

Currently, bodily biomarkers can be monitored through a wardrobe-load of wearables, but they usually need batteries for power and wireless communication systems to transmit data. Using biosensitive inks (bio-inks), the Harvard and MIT design is self-contained, and since it works on simple chemical reactions it doesn’t require power for any data processing or transmission.

The inks interact with the body’s interstitial fluid, which transfers nutrients into cells and carries waste out of them. The fluid works closely with blood plasma, meaning it acts as a decent indicator of the chemical concentrations in the blood at a given time.
