Activated carbon is a form of carbon that is shot through with nanosized holes that increase the material's surface area and allow it to catalyze more chemical reactions and store more electrical charge. But due to the way it is produced, most of the pores within it aren't interconnected, limiting the material's ability to transport electricity. Now researchers at Stanford University have created a "designer carbon" with greater pore connectivity and therefore greater electronic conductivity, which enables superior energy-storage performance.
As electronic devices are becoming outdated at an increasingly fast pace, e-waste continues to be a huge problem.
That's why scientists from the University of Wisconsin-Madison have
started producing "wooden" semiconductor chips that could almost
entirely biodegrade once left in a landfill. As an added bonus, the
chips are also flexible, making them prime candidates for use in
As digital technology becomes more ubiquitous and the Internet of Things takes shape, the question of how to power it all becomes more pressing. Japanese technology firm Ricoh is looking at its new "energy-generating rubber" as one solution. According the company, the new piezoelectric polymer converts pressure and vibration into electric energy with high efficiency, yet is extremely flexible and durable.
Texting is so much a part of modern life that some people can't even pause for a meal of fried chicken without sending a message. As part of an advertising campaign and in an effort to avoid an epidemic of greasy smartphone screens, KFC restaurants in Germany have been giving away paper tray liners with built-in Bluetooth keyboards, so patrons can text away while munching on their extra crispy.
Expanding on previous research into electronic devices that dissolve in water once they have reached the end of their useful life, researchers at the University of Illinois have developed a new type of "transient" electronic device that self-destructs in response to heat exposure. The work is aimed at making it easy for materials from devices that usually end up in landfill to be recycled or dissolved completely.
A supermarket in France has become the first in the world to install an "indoor positioning system" created by Philips. The LED-based technology acts like a sat-nav for shoppers, providing in-store directions to shopping list items via their phones.
Researchers have successfully transferred monolayer graphene to fibers commonly used in the textile industry. The transparent, flexible material could one day be used to create embedded wearable electronics, such as phones, fitness trackers or MP3 players.
If you’re into electronics as
a hobbyist, technician, or professional engineer, you know that you can spend
many hours designing circuits, sourcing components, and breadboarding or
soldering a project all together before you find out if your creation actually works. Wouldn’t
it make life simpler if you could just start with a basic, multi-function
controller and a few plug and play peripherals to get something – anything – up
and running straight away and then which you could tweak and add to as you go?
The makers of a new electronic design tool thought that this would be a good
idea too and have created Cubit, a make anything platform that allows drag and
drop software control over snap together hardware. Join Gizmag as we try a few builds to test out it out.
If you're like a lot of phone junkies and replace your phone as soon as the latest thing comes along, you'll know that often the hardware in the old phone is perfectly fine, even the battery. But fancier new screens and more powerful processors mean that battery life usually remains a problem, making battery packs a popular accessory. Enlighten's Better Re lets you get some more use out of your old phone's battery, by allowing it to slot into an adjustable external battery charger for your new phone.
Using a matrix of nano-sized memristors, researchers
working at the Royal Melbourne Institute of Technology (RMIT) and the
University of California, Santa Barbara claim to have constructed the world’s
first electronic memory cell that effectively mimics the analog process of the
human brain. By storing memories as multiple threads of varying information,
rather than a collection of ones and zeroes, scientists believe that this
device may prove to be the first step towards creating a completely artificial,
