Accutronics has launched two new lithium-ion batteries in its Intel lion series of credit card sized batteries. These new smart batteries are ideal for high-tech portable applications including tele-healthcare devices, test and measurement equipment and wearable computers

The CC2300 and CC3800 batteries allow integration of smart lithium ion battery into handheld portable products with minimal effort and cost.

The products feature 3.7V Lithium Ion cell technology coupled with impedance tracking fuel gauge, an active protection system, and a compact connector.

The batteries feature an active electronic protection system that prevents them from being overcharged, over discharged or short circuited.

In addition, they have impedance tracking fuel gauge that constantly tracks battery status, providing information such as remaining battery capacity, state of charge, run time to empty, battery voltage and temperature.


Super capacitors (also known as electric double-layer capacitors – EDLC), are electrochemical capacitors with energy densities hundreds of times larger than conventional capacitors, making them suitable for energy storage applications.

Researchers have used computer simulations for how super capacitors are able to store electric charge.

Researchers from France, the UK and the US have used realistic molecular-scale computer simulations to examine how ions are arranged in carbide-derived carbon electrodes, which has cast light on the origin of super capacitance at the atomic scale.

In order to examine the behavior of ionic liquids at the interface with carbon electrodes, the team designed a realistic simulation cell consisting of an ionic liquid electrolyte surrounded by two porous electrodes which could be held at a constant potential.

When two different voltages were applied between the electrodes, the team could compare how ions are organized in the electrified pores of electrodes and how they behave at a planar graphite surface.

Mojtaba Mirzaeian who investigates super capacitors at Queen’s University Belfast, UK, says the simulations offer new and useful information on the mechanism of ion separation and charge storage inside micro porous electrodes.

This could be beneficial in the preparation of micro porous carbons with desired porous structures to enhance the capacity and performance of EDLCs,’ he says.

Missing Calls? Nokia Will Pair It With Your Tattoo

Your boss calls on your mobile phone and your tattoo starts to vibrate.

Yes, it is spooky but could be a reality soon with the recent patent that Finnish handset maker, Nokia has filed. The technology will work on the concept of haptics.

It basically deals with the sense of touch that is ignited by applying vibrations or forces to your skin.

According to Nokia’s plan, they want to work on tattoos that will be made using ferromagnetic ink that will receive commands from your mobile phone.

It will either tell you about the caller through vibration or can also be attuned to inform if it is a call, text or video message. These tattoos can either be worn on the skin or inked.

How it works??

Nokia proposes that the material worn on the body or painted on the skin can detect a magnetic field and emit a vibration with options for different kind of haptic feedbacks, among which the user may choose to personalize the device.

If you’ve ever touched a cellular phone, there’s a good chance you’ve been exposed to haptics. Before you start reaching for the hand sanitizer and calling your doctor , know that the only infectious thing about haptics is its amazing ability to take gameplay, touch screen devices, and portable electronic user experiences to an entirely different level.

Haptic technology, or haptics, is a tactile feedback technology which takes advantage of the sense of touch by applying forces, vibrations, or motions to the user.

Haptic technology has made it possible to investigate how the human sense of touch works by allowing the creation of carefully controlled haptic virtual objects..



now waiting for this…when it will launch in market???

Honda 1.6-litre i-DTEC diesel engine

Honda Motor Europe’s President, Manabu Nishimae, announced the 1.6-liter i-DTEC engine in the new Civic would deliver CO2 emissions of 95g/km*

About i-DTEC:-

This 1.6 liter i-DTEC turbo diesel engine will pump out 120 BHP of peak power at 4000 rpm along with 300 Nm of peak torque at 2000 rpm .

The new 1.6-liter i-DTEC engine is the first drive t from Honda’s new Earth Dreams Technology engine series which introduced in Europe.

This new 1.6 liter of i-DTEC turbo diesel engine                                

emits low CO2, which comes out to be 95 grams
