Material can turn sunlight, heat and movement into electricity—all at once

Posted by in categories: privacy, solar power, sustainability, wearables

Many forms of energy surround you: sunlight, the heat in your room and even your own movements. All that energy—normally wasted—can potentially help power your portable and wearable gadgets, from biometric sensors to smart watches. Now, researchers from the University of Oulu in Finland have found that a mineral with the perovskite crystal structure has the right properties to extract energy from multiple sources at the same time.

Perovskites are a family of minerals, many of which have shown promise for harvesting one or two types of at a time—but not simultaneously. One family member may be good for solar cells, with the right properties for efficiently converting solar energy into electricity. Meanwhile, another is adept at harnessing energy from changes in temperature and pressure, which can arise from motion, making them so-called pyroelectric and piezoelectric materials, respectively.

Sometimes, however, just one type of energy isn’t enough. A given form of energy isn’t always available—maybe it’s cloudy or you’re in a meeting and can’t get up to move around. Other researchers have developed devices that can harness multiple forms of energy, but they require multiple materials, adding bulk to what’s supposed to be a small and portable device.

Wireless power transmission safely charges devices anywhere within a room

Posted by in categories: internet, robotics/AI

A new method developed by Disney Research for wirelessly transmitting power throughout a room enables users to charge electronic devices as seamlessly as they now connect to WiFi hotspots, eliminating the need for electrical cords or charging cradles.

The researchers demonstrated their method, called quasistatic cavity resonance (QSCR), inside a specially built 16-by-16-foot room at their lab. They safely generated near-field standing magnetic waves that filled the interior of the room, making it possible to power several cellphones, fans and lights simultaneously.

“This new innovative method will make it possible for electrical power to become as ubiquitous as WiFi,” said Alanson Sample, associate lab director & principal research scientist at Disney Research. “This in turn could enable new applications for robots and other small mobile devices by eliminating the need to replace batteries and wires for charging.”

SatRevolution building new satellite plant in Poland with partners APWorks

Posted by in categories: 3D printing, satellites

Polish company SatRevolution have announced plans to create a new satellite production plant in Poland and use 3D printing to develop the country’s first satellites. SatRevolution will partner with APWorks to produce a prototype of the Światowid satellite. Airbus subsidiary, APWorks, will provide metal additive manufacturing solutions to the Polish developers.

The Światowid is intended to measure cosmic radiation and electromagnetic interference. To facilitate launching, the design was developed in line with the cube-sat parameters. Measuring 10 × 10 × 20 cm, the satellite will weigh 2 kg.

The project will reportedly require $50 million to complete, with the satellite production facility planned to be built near the Polish city of Wroclaw.

Australian entrepreneur reveals ‘brain-controlled’ telepresence robot

Posted by in categories: education, robotics/AI

Luv this.


Australian entrepreneur reveals brain-controlled telepresence robot. Teleport utilizes brain controlling interface to follow the focal point of a user’s mind and serve various fields of life.

Australian Developer has released a telepresent robot that will let the users attend school or work distantly. People, with a limited mobility of upper limb, will remotely attend tasks through this off-the-shelf mind controlling interface costing 200 UDDs.

Nanoelectronic thread probes form reliable, scar-free integration with the brain

Posted by in categories: engineering, neuroscience

Another new interface method.


Engineering researchers at The University of Texas at Austin have designed ultra-flexible, nanoelectronic thread (NET) brain probes that can achieve more reliable long-term neural recording than existing probes and don’t elicit scar formation when implanted.

The researchers described their findings in a research article published in Science Advances (“Ultraflexible nanoelectronic probes form reliable, glial scar–free neural integration”).

Brain implants might soon restore vision to the blind, improve digestion, relieve PTSD symptoms

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

[Brain implant experiments] like those that let a paralyzed person swig coffee using a robotic arm, or that let blind people “see” spots of light, have proven the huge potential of computers that interface with the brain. But the implanted electrodes used in such trials eventually become useless, as scar tissue forms that degrades their electrical connection to brain cells.

[However,] tests will begin in monkeys of a new implant for piping data into the brain that is designed to avoid that problem. [Led by Harvard researchers,] the project is intended to lead to devices that can restore vision to blind people long-term…[The device will] go beneath the skull but can rest on the surface of an animal’s brain, instead of penetrating inside the organ.

Inkjet-printable stretchy circuits could lead to huge e-wallpaper screens

Posted by in categories: electronics, health

When and if that hurdle is overcome, the researchers say that the easily-fabricated stretchy technology could begin to find commercial applications, in devices like rubbery wrist-worn health trackers, deformable tablets and electronic wallpaper that can make huge screens out of entire walls.

“We have created a new technology that is not yet available,” says Wang. “And we have taken it one big step beyond the flexible screens that are about to become commercially available.”

The research was published in the journal ACS Nano.

Thin, built-in batteries to free up valuable space on CubeSats

Posted by in categories: habitats, satellites

Real estate is a valuable commodity aboard a CubeSat, a compact satellite about the size of a shoebox, so the smaller each component can be made, the better. To that end, scientists at NASA’s Kennedy Space Center and the University of Miami are developing a thin, solid-state battery, which could not only save space for more important instruments aboard satellites, but also provide power on other planets, in cars or within the walls of a home.

At less than 3 mm (0.1 in) thick, the new batteries could be incorporated into the structure of pint-sized satellites, rather than taking up room in the area designated for research instruments. The batteries are made by sandwiching a solid-state battery layer between two layers of compressed carbon fiber.

“Creating a structural battery material could revolutionize the way NASA operates small payloads,” says senior principal investigator, Luke Roberson. “Rather than placing a battery in the experiment taking up 20 to 35 percent of the available volume, the battery now resides in the payload structure, thereby opening up additional free space for researchers to perform more science.”
