As a newer and cleverer solution to solve the problem of “overcharging”, Bracketron’s GreenZero chargers can automatically shut off once your devices is fully charged. The GreenZero, available in a Mushroom and Stone styles, is compatible with iPhone, USB, and Android specific models, shutting off automatically to save energy and avoid top-off stress on batteries. Set to be released at CES in Las Vegas later this month, the GreenZero will be priced at $22 to $29.

PumPing Tap is a 2011 red dot design concept winner, which can cleverly solve the problem of wastage of electricity by automatically ejecting a plug when the appliance is switched off. About ten minutes later after you’ve turned your device off but haven’t unplugged it, the socket will then eject the plug, so as to completely cut off the electricity.

The development of bio-batteries is now pushed to a new level, after electronics giant Sony announced that it has developed a battery powered by paper. The batteries were demonstrated at the Eco-Products exhibition in Tokyo, where they have successfully powered a mini fan to work. Sony’s actually utilizes cellulose enzymes to accomplish this technology: after breaking down the paper, the enzymes were left with sugar that had been created from the cellulose; and then the sugar is processed to create hydrogen ions and electrons. Theoretically, a piece of A4 paper is expected to produce about 18 watts of electricity, equivalent to the electricity power of six AA batteries. But currently the electricity power we get is fewer than that, which is also a drawback of this bio-battery.

New developments have been found in the Electronic Skin field, because researchers from the Lawrence Berkeley Lab have created both flexible and stretchable electronic skin using semiconductor-enriched carbon nano tubes. The electronic skin is proved capable of detecting and responding to touch, and expected to provide lithography-free fabrication of low-cost flexible and stretchable electronics in the future in combination with inkjet printing of metal contacts.

Researchers from Northwestern University have developed a breakthrough battery technology that features both high efficiency of re-charging and better electricity energy storage. Compared with ordinary batteries, the new lithium ion batteries allows for using 10 times longer and recharges 10 times quicker. Generally it could keep your cellphone charged for a week and recharge in 15 minutes; when applied on electric cars, the battery can power it to run 500 miles with 10 minutes of charging.

Till now, the International Funkausstellung Berlin 2011 has brought us many surprising designs and products, and today we’d like to add a new one to the list of innovative electronics. It is Sony’s “Lenticular Sheet”, a thin film that can be places in front of any laptop screens to turn them into glass-free 3D displays. With such a product, 3D fanciers would then enjoy 3D films without needing to wear glasses any more. [Read the rest of this entry...]

The Airsketcher, which looks the same as ordinary fans, actually has an astonishing function that it can automatically “follow” the users and bring them with cool air. How? Because there’s a small-sized webcam built inside the fan, which can track a specially-made flag so as to locate the users. Besides, the fan can also recognize different symbols and act accordingly. Therefore the users can easily switch on/off or adjust the speed by showing certain symbols to the fan. [Read the rest of this entry...]

Etymotic Research’s HD-15 High-Definition electronic earplugs is the ever-best gadget that can both protect your ears from loud noises and let people to hear when it isn’t noisy. Note that you can always have the earplugs in your ears, no needing to take them out or in from time to time. [Read the rest of this entry...]

Researchers from the University of Illinois have exhibited their latest achievement – the Electronic Skin via the Internet. It is hair-thin, constructed with sensors, antenna, LED and other parts and powered by built-in solar batteries to monitor a person’s heartbeat, brain activity, muscle contractions and so on. If you put it besides your throat, the device can even “hear” your words so as to accomplish certain tasks. It can be easily applied to anything, without need for glue. When such amazing things used in the medical field, we bet we humans can benefit more from the advanced technology.
