New York, Dec 11, 2016: You may soon be able to charge cell phones and power Bluetooth headsets with the swipe of a finger as scientists have developed a device that can harvest energy from human motion.

According to a research published in the journal “Nano Energy”, a foldable keyboard called “Biocompatible Ferroelectret Nanogenerator” (FENG) that operates by touch and for which no battery is needed can harvest energy from human motion.

“We are on the path toward wearable devices powered by human motion,” said Nelson Sepulveda, Associate Professor at Michigan State University. He added, “What I foresee, relatively soon, is the capability of not having to charge your cell phone for an entire week, for example, because that energy will be produced by your movement.”

The scientists used the low-cost device to successfully operate an LCD touch screen, a bank of 20 LED lights and a flexible keyboard, all with a simple touching or press motion and without the aid of a battery.

According to the scientists, the process starts with a silicone wafer, which is then fabricated with several layers of environmentally friendly substances including silver, polyimide and polypropylene ferroelectret.

“Ions are added so that each layer in the device contains charged particles. Electrical energy is created when the device is compressed by human motion, or mechanical energy,” the study explained.

FENG is as thin as a sheet of paper and can be adapted to many applications and sizes.

“Advantages such as being lightweight, flexible, biocompatible, scalable, low-cost and robust could make FENG an alternative method in the field of mechanical-energy harvesting for many autonomous electronics such as wireless headsets, cell phones and other touch-screen devices,” the study suggested.

When FENG is folded, the amount of voltage a person creates is exponentially increased in it.

“You can start with a large device, but when you fold it once, and again, and again, it is now much smaller and has more energy,” said Sepulveda. (IANS)

Aadhaar Helpline Mystery: French Security Expert Tweets of doing a Full Disclosure Tomorrow about Code of the Google SetUP Wizard App

Google’s admission that it had in 2014 inadvertently coded the 112 distress number and the UIDAI helpline number into its setup wizard for Android devices triggered another controversy on Saturday as India’s telecom regulator had only recommended the use of 112 as an emergency number in April 2015.

After a large section of smartphone users in India saw a toll-free helpline number of UIDAI saved in their phone-books by default, Google issued a statement, saying its “internal review revealed that in 2014, the then UIDAI helpline number and the 112 distress helpline number were inadvertently coded into the SetUp wizard of the Android release given to OEMs for use in India and has remained there since”.

However, the Telecom Regulatory Authority of India (TRAI) recommended only in April 2015 that the number 112 be adopted as the single emergency number for the country.

According to Google, “since the numbers get listed on a user’s contact list, these get  transferred accordingly to the contacts on any new device”.

Google was yet to comment on the new development.

Meanwhile, French security expert that goes by the name of Elliot Alderson and has been at the core of the entire Aadhaar controversy, tweeted on Saturday: “I just found something interesting. I will probably do full disclosure tomorrow”.

“I’m digging into the code of the @Google SetupWizard app and I found that”.

“As far as I can see this object is not used in the current code, so there is no implications. This is just a poor coding practice in term of security,” he further tweeted.

On Friday, both the Unique Identification Authority of India (UIDAI) as well as the telecom operators washed their hand of the issue.

While the telecom industry denied any role in the strange incident, the UIDAI said that he strange incident, the UIDAI said that some vested interests were trying to create “unwarranted confusion” in the public and clarified that it had not asked any manufacturer or telecom service provider to provide any such facility.

Twitter was abuzz with the new development after a huge uproar due to Telecom Regulatory Authority of India (TRAI) Chairman R.S. Sharma’s open Aadhaar challenge to critics and hackers.

Ethical hackers exposed at least 14 personal details of the TRAI Chairman, including mobile numbers, home address, date of birth, PAN number and voter ID among others. (IANS)
