Nanomaterial charges everyday batteries in seconds
If you want a battery that charges in seconds rather than hours, you go for a supercapacitor. There are some catches to that, though: either you give up the long-lasting energy of a chemical battery (like the lithium pack in your phone) or have to resort to exotic storage tech to get a long lifespan. Drexel researchers think they have a better balance. They've developed electrodes based on a nanomaterial, MXene, that promise extremely quick charging times for chemical batteries. The near-2D design combines an oxide-metal 'sandwich' with hydrogel to create a structure that's extremely conductive, but still lets ions move freely as the battery builds up a charge. In the lab's design, you can charge MXene electrodes within "tens of milliseconds" -- you could top up a phone in seconds or an electric car in minutes.
Drexel University intros MacBook Pro vending machine
Drexel University in Philadelphia has created a solution for students who need to use a computer on campus but don't have immediate access to one of their own: A free MacBook vending machine. Ok, so it's not exactly a vending machine, and the computers are only loaned to the students for free 5-hour intervals, but it's still a rather interesting system. The kiosk scans each student's ID before allowing them to take one of the dozen 15-inch MacBook Pro notebooks from its stock. The computers can be used for a total of five hours at no charge, with each additional hour costing $5. The MacBooks are equipped with security sensors to ensure they don't go missing. If the program proves beneficial for students, the university is considering adding iPad kiosks as well. Where were these when I was in college? [Via: Gizmodo]
Four HUBOs 'Come Together' for a Drexel Engineering MET-lab demo
Robot Beatles cover band? Check. Students at Drexel University's Music and Entertainment Technology Lab (MET-lab) have developed software that allows HUBO robots to create tunes following a musical score. The Roboband plays the song without human control during the performance -- a demo that combines humanoid tech and creative expression research. Four HUBOs jam the arrangement of the Beatles' "Come Together" by MET-lab student Matthew Prockup on Ringo's mini-kit and three "Hubophones." Drexel and seven other universities in the States are part of a humanoid research collaboration with KAIST, the designer of the HUBO robot.
Drexel University turns to 3D scanners, printers to build robotic dinosaurs
3D printers, 3D scanners and robotics are usually more than enough on their own to get us interested in something, but a team of researchers at Drexel University have played one other big trump card with their latest project -- they've thrown dinosaurs into the mix. As you can probably surmise, that project involves using a 3D scanner to create models of dinosaur bones, which are then reproduced (at a somewhat smaller scale) using a 3D printer. The researchers then hope to use those to build working robotic models that they'll use to study how dinosaurs and other prehistoric animals may have moved and lived in their environments. That work will start with a dinosaur limb that they expect to have completed by the end of the year, after which they say it will take a year or two to build a complete robotic dinosaur replica.
Fingercams / brain scanners to make mice and multitouch displays seem archaic
Oh sure, we've known that mice were going the way of the Dodo for eons now, but a nice compilation over at Wired details just how close we are to relying on brain scanners and fingercams (among other unorthodox input methods) to do everything from play games to flip through photo albums. For instance, at Drexel University's RePlay Lab, students are currently "trying to measure the level of neurotransmitters in a subject's brain to create games where mere thought controls gameplay." Another example of how fingers are better used away from the left / right click is FingerSight, a technology that would enable cursor inputs to be, um, inputted by simply waving one's hand around. Unfortunately, the reality of all of this fantastic research is that we're still years away from pushing the fabled keyboard / mouse combo aside, but you aren't apt to find any FPS fanatics kvetching about that.
Using an iPod while driving is distracting: duh
Man, we need to get in on the cash cow feeding all these driver distraction studies. A new study conducted by Drexel University found that using an iPod while driving has "significant effect" on driver performance. The study monitored 12 people who were asked to "drive" in a simulator while selecting and playing music, video and podcasts on their iPods. The result? No surprise: searching for media caused drivers to slow down and veer left or right whereas watching videos (!) "significantly affected" car-following speed. Hey, can we get some funding to prove that knitting a sock affects driving performance as well? Hell, let's just ban it all and get back to the intrinsically safe concept of propelling 2,000 pounds of steel and glass down the road at 80 feet per second.
Breakthrough in ferroelectric materials could enable million-GB thumbdrives
While we have to agree with certain Engadget readers who feel that 640KB of RAM is plenty for most computing tasks, those darn scientists just keep looking for ways to stuff more and more data into smaller spaces. The latest breakthrough on the storage tip comes courtesy of researchers from Drexel and Penn, who have found a way to stabilize the simple physical property of ferroelectricity at the nano scale, making possible such obviously unnecessary densities as 12,800,000GB per cubic centimeter. Ferroelectric materials are usable as memory because they possess the ability to switch electric charges in so-called dipole moments, but before Drexel's Dr. Jonathan Spanier and colleagues decided to embed the materials in water, it had previously been impossible to screen those dipole moments at scales small enough to be useful. Don't expect to be able to buy a zillion gig, water-filled iPod anytime soon, though, as the research team still faces significant hurdles in actually assembling the nanowires that would make up such a drive with the proper density as well as developing a method of efficiently reading and writing data.
