New Delhi, August 1, 2017: A super touch sensitive material has been developed by a team of Indian and French scientists. This material has the ability to enhance response rate by thousand times from existing materials. A super touch sensitive material has been developed by a team of Indian and French scientists. This material has the ability to enhance response rate by thousand times from existing materials.

The material is made of Quantum Dots (QD) with liquid crystals. QDs are tiny semiconductor particles which are only several nanometers in size. This material has its applications in semiconducting devices with pico-ampere sensitivity and it is able to mimic any biological system.

This system can also store electrical energy more efficiently.

For this specific purpose, the team controlled the assembly of quantum particles in liquid crystal matrix by altering the concentration of QDs. Professor Sandeep Kumar of Raman Research Institute, Bengaluru was responsible for preparing the QDs that were used in this project.

In a conversation with Indian Science Journal, Dr Dharmendra Pratap Singh, the corresponding author of the study and a post doctoral researcher at University of the Littoral Opal Coast in France, said, “This invention opens up development of semiconducting energy storage devices.We are planning to do some more experiments to make a battery for pocket devices using this material by next year.”

Dr. Singh also mentioned that the advantage of the new touch sensitive material is its ability to store more energy in less space, that can be very-utilised for applications like mobile handset, especially new age smartphones.

According to ANI report, the research details have been published in the latest edition of Journal of Physics D: Applied Physics.

Currently, touch sensitive materials are made of liquid crystals on Indium Tin Oxide (ITO) in IPS mode (in-plane switching mode), which means that a device captures traffic for the sensor and then forwards a copy for analysis to the sensor.

Scientists have been trying for some time now to develop organic light emitting diode (OLED) devices which could possibly help in reducing the operating voltage significantly while improving the efficiency and light output.

The five most common types of touch screen technology are :  5-Wire Resistive, Surface Capacitive, ProjectedCapacitive, SAW (Surface Acoustic Wave), and Infrared. The most widely used touch technology today is 5-Wire Resistive Touch.

Resistive touch screens were invented in 1970. A resistive screen basically consists of a number of layers. It functions like this: when the screen is pressed, the mechanism pushes the outer layer onto the next layer, the technology is programmed to sense that pressure being applied and register input.

Resistive touch screens are widely versatile, users can use them with a finger, a fingernail, a stylus or any other object. They are very user-friendly as well.

Capacitive touch screen – a control display that uses the conductive touch of a human finger or a specialized device for input, was designed first but they were eclipsed in the early years of touch-screen technology by the invention of resistive touch screens. A fun fact, American inventor Dr G. Samuel Hurst developed resistive touch screens almost accidentally.

How Gionee Aims to be Among Top 5 Smartphone Brands in India


After a brief hiatus, second-tier Chinese handset maker Gionee is geared up for a big splash in India with new smartphone launches amid a revamped strategy to be among the top five players in the country, a senior company executive has said.

The smartphone maker confirmed its restructuring plans last month, saying it will adopt a new business model under which distributors across the country would do their own marketing to enhance sales.

“India is becoming the second-largest mobile phone market globally and, for Gionee, it is as important as China or the European market. It is our commitment to invest further in this market to bring major change,” David Chang, Global Sales Director, Gionee India, told IANS in an interview.

“Setting up a manufacturing plant will help us in making all our phones by ourselves,” Chang added.

“We are aiming to get into the top five smartphone brands in the second half of 2018. In the first half of 2019, we will target to be among the top three players in the Indian smartphone market,” said the Gionee executive.

Buoyed by the response of its first bezel-less display smartphone — the “M7 Power” which was launched in November 2017 — the smartphone maker is set to introduce a series of full-view display devices.

The company said it will launch its first smartphone for 2018 as early as next month. Wikimedia Commons


This will be followed by several other bezel-less smartphone launches within the price bracket of Rs 10,000-Rs 15,000 — essentially either selfie-focused or battery-centric devices.

In an attempt to take on its rivals, the handset maker is also exploring the in-display fingerprint scanning technology.

“We are working on this new technology. We are working on a smartphone with under-the-display fingerprint scanner which would be launched globally,” Chang noted. Wikimedia Commons

The company will also introduce wireless chargers by the end of this year.

Acknowledging that its online distribution channel is not up to the mark, Chang said: “We started investing more in online channels beginning October 2017 and we believe online and offline channels are equally important. Now, we want to be more involved and would invest more in our online partners.”

“We have our exclusive stores, but right now we will focus more on building relationships with retailers directly,” Chang noted.

The handset maker is also mulling to restructure its strategy for online channels. Wikimedia Commons


“Gionee would be partnering with Amazon India, Flipkart and Paytm for introducing our new devices on their platforms.

“We will choose our best-selling models to be showcased online. We’ll also make sure there is no difference in price of the product that is available both online and offline,” Chang said.

Gionee, which has more than 600 service centres in India, said it will also work towards further strengthening its after-sales services in the country. IANS
