“The story of technology is in fact the story of textiles. From the most ancient times to the present, so too is the story of economic development and global trade. The origins of chemistry lie in the colouring and finishing of cloth. The textile business funded the Italian Renaissance and the Mughal Empire; it left us double-entry bookkeeping and letters of credit, Michelangelo’s David and the Taj Mahal. As much as spices or gold, the quest for fabrics and dyestuffs drew sailors across strange seas. In ways both subtle and obvious, textiles made our world.” Read more

Google Wants You to Control Your Gadgets with Finger Gestures, Conductive Clothing — Tom Simonite MIT Technology Review

Small gadgets such as smart watches can be frustrating to use because their tiny buttons and touch screens are tricky to operate. Google has two possible solutions for the fat finger problem: control your gadgets by subtly rubbing your finger and thumb together, or by swiping a grid of conductive yarn woven into your clothing.

The first of those two ideas works thanks to a tiny radar sensor that could be integrated into, say, a smart watch and can detect fine motions of your hands from a distance and even through clothing. Levi Strauss announced today that it is working with Google to integrate fabric touch panels into its clothing designs. The new projects were announced at Google’s annual developer conference in San Francisco Friday by Ivan Poupyrev, a technical program lead in Google’s Advanced Technology and Projects research group.

Terminator draws closer with shape-shifting liquid metal motor

Posted by in categories: chemistry, engineering, materials, Skynet

by — C/net
There are some concepts from sci-fi that really should never, ever see the light of day. The T-1000 — the murderous robot made of shifting liquid metal — is arguably one of them, but that doesn’t mean it doesn’t exhibit some interesting ideas, even if they do seem impossible.

Seem, of course, being the operative word — because researchers in China have just created the world’s first liquid metal robot that can both change shape and power itself.

“The soft machine looks rather intelligent and [can] deform itself according to the space it voyages in, just like [the] Terminator does from the science-fiction film,” Jing Liu from Tsinghua University in Beijing, China, told New Scientist. “These unusual behaviours perfectly resemble the living organisms in nature.” Read more

Black Phosphorus: The Birth of a New Wonder Material

Posted by in category: materials

Emerging Technology From the arXiv — MIT Technology Review

Materials scientists have discovered how to make black phosphorus nanosheets in large amounts, heralding a new era of nanoelectronic devices.

In the last few years, two-dimensional crystals have emerged as some of the most exciting new materials to play with. Consequently, materials scientists have been falling over themselves to discover the extraordinary properties of graphene, boron nitride, molybdenum disulphide, and so on.

A late-comer to this group is black phosphorus, in which phosphorus atoms join together to form a two-dimensional puckered sheet. Last year, researchers built a field-effect transistor out of black phosphorus and showed that it performed remarkably well. This research suggested that black phosphorous could have a bright future in nanoelectronic devices.

BitCoin, Cryptocurrency, and Blockchain Technology — The Ethereum Primer

Quoted: “Ethereum will also be a decentralised exchange system, but with one big distinction. While Bitcoin allows transactions, Ethereum aims to offer a system by which arbitrary messages can be passed to the blockchain. More to the point, these messages can contain code, written in a Turing-complete scripting language native to Ethereum. In simple terms, Ethereum claims to allow users to write entire programs and have the blockchain execute them on the creator’s behalf. Crucially, Turing-completeness means that in theory any program that could be made to run on a computer should run in Ethereum.” And, quoted: “As a more concrete use-case, Ethereum could be utilised to create smart contracts, pieces of code that once deployed become autonomous agents in their own right, executing pre-programmed instructions. An example could be escrow services, which automatically release funds to a seller once a buyer verifies that they have received the agreed products.”

Bitcoin, Cryptocurrency, and Blockchain Technology — Voting Systems

Quoted: “Bitcoin technology offers a fundamentally different approach to vote collection with its decentralized and automated secure protocol. It solves the problems of both paper ballot and electronic voting machines, enabling a cost effective, efficient, open system that is easily audited by both individual voters and the entire community. Bitcoin technology can enable a system where every voter can verify that their vote was counted, see votes for different candidates/issues cast in real time, and be sure that there is no fraud or manipulation by election workers.”

BitCoin, Cryptocurrency, and Blockchain Technology — FACTOM

Quoted: “The Factom team suggested that its proposal could be leveraged to execute some of the crypto 2.0 functionalities that are beginning to take shape on the market today. These include creating trustless audit chains, property title chains, record keeping for sensitive personal, medical and corporate materials, and public accountability mechanisms.

During the AMA, the Factom president was asked how the technology could be leveraged to shape the average person’s daily life.”

Kirby responded:

“Factom creates permanent records that can’t be changed later. In a Factom world, there’s no more robo-signing scandals. In a Factom world, there are no more missing voting records. In a Factom world, you know where every dollar of government money was spent. Basically, the whole world is made up of record keeping and, as a consumer, you’re at the mercy of the fragmented systems that run these records.”

A New Economic Layer — BitCoin, Cryptorcurrency, and Blockchain Technology

Preamble: Bitcoin 1.0 is currency — the deployment of cryptocurrencies in applications related to cash such as currency transfer, remittance, and digital payment systems. Bitcoin 2.0 is contracts — the whole slate of economic, market, and financial applications using the blockchain that are more extensive than simple cash transactions like stocks, bonds, futures, loans, mortgages, titles, smart property, and smart contracts

Bitcoin 3.0 is blockchain applications beyond currency, finance, and markets, particularly in the areas of government, health, science, literacy, culture, and art.

Morphing material could allow robots to switch between hard and soft states

Posted by in category: materials

Kurweil AI

A new Terminator T-1000 robot-style material made of wax and foam — and capable of switching between hard and soft states — could be used to build morphing surgical robots that move through the body to reach a desired location without damaging organs or vessels along the way.

Robots built from the material, described in a new paper in the journal Macromolecular Materials and Engineering, could also be used in search-and-rescue operations to squeeze through rubble looking for survivors, says Anette Hosoi, an MIT professor of mechanical engineering and applied mathematics who led the research team.
