Beijing, July 26, 2017: Chinese researchers have developed a user-interactive electronic skin that can change colour — an ability associated with animals such as chameleons, octopuses and squid. The changes are perceptible to the human eye without much strain.

Though science has been able to replicate these abilities with artificial skin, the colour changes are often only visible to the naked eye when the material is put under huge mechanical strain.

The research conducted by Tsinghua University in Beijing can have applications in robotics, prosthetics and wearable technology.

“This user-interactive e-skin should be promising for applications in wearable devices, robots and prosthetics in the future,” the study mentioned.

The researchers employed flexible electronics made from graphene, in the form of a highly-sensitive resistive strain sensor, combined with a stretchable organic electrochromic device.

“To obtain good performance with a simple process and reduced cost, we designed a modulus-gradient structure to use graphene as both the highly sensitive strain-sensing element and the insensitive stretchable electrode of the ECD layer,” said Tingting Yang from Tsinghua University, in a paper published in the journal 2D Materials.

The researchers found that subtle strain — between zero and 10 per cent — was enough to cause an obvious colour change, and the RGB value of the colour quantified the magnitude of the applied strain.

The study noted that the capability for interactive colour changes with such a small strain range has been rarely reported before. (IANS)

Cryptocurrencies are gaining robust popularity amongst the masses due to its decentralised approach. Since cryptocurrencies eliminate the intervention of institutions and Governments in its transactions, it is more transparent in its operations. People might be well aware of the popular crypto Bitcoin, but there are many other better performing coins like Litecoin, Bitcoin Cash, Ethereum and Ripple. If you intend to buy litecoin, then you should have a crypto wallet which can store the litecoins for you. A crypto wallet acts like a regular wallet to keep the money safe, but it does not actually hold any physical form of cryptos. 

Find below some of the Litecoin wallets to secure your LTC:

Ledger Nano S: It is a hardware wallet which can be easily plugged into your system like a USB device. Ledger nano s is considered safer than online wallets as they can be physically carried and plugged off the device thereby providing less space for any fraudulent activities. Ledger nano is equipped with private keys for better security and is the best choice if you have LTC in large numbers.

Trezor wallets: Trezor was a child from the Satoshilabs and is the first hardware wallet meant for providing more security to the coins. Trezor renders its support to many coins like Dash, ZCash, Litecoin and Dogecoin. It provides a 9-digit pin code to store your Litecoins even offline. Trezor is one of the lightest and portable Litecoin wallets.

Exodus: Exodus is a popular desktop wallet which provides space for storing many cryptocurrencies including Bitcoin, Litecoin, ZCash and Ripple. Exodus has an inbuilt connection with famous cryptocurrency exchange Shapeshift allowing easing access to LTC to BTC converter and BTC to LTC exchange.  Exodus is a multi-currency wallet and hence is a favourite for many crypto enthusiasts.

Jaxx: Jaxx wallet supports desktop and mobile applications. Jaxx provides a user-friendly experience for all the 13 cryptocurrencies it supports. One amongst them is Litecoin. Jaxx wallet can be used in IOS, Android, Windows and Linux devices. It has a tie-up with Shapeshift which is a leading crypto exchange thus allowing you to buy Bitcoin anonymously with credit card.

Electrum LTC: To get away with the slow speed of heavy Litecoin core wallets, you can shift to a lite wallet like Electrum LTC to store Litecoins. Electrum is a desktop wallet which works without downloading the entire Litecoin blockchain.  Electrum LYTC wallet is protected by a 12 digit seed key and is available for different types of desktops like MAC, Windows and Linux.
