Graphene Sensor Enables Mind Control of Robots, A new Technology

Published

on

technology

Australian researchers have developed a new brain-computer interface (BCI) that utilizes the incredible properties of graphene, a carbon-based material just one atom thick. With funding from Australia’s Defense Innovation Hub, the team at the University of Technology Sydney (UTS) developed an effective “dry” sensor made from silicon and graphene, which can read brain signals and translate them into commands for machines. This breakthrough technology could one day make hands-free and voice-free control of robots possible, without the need for external devices such as keyboards, touchscreens, or hand-gesture recognition.

Current BCIs that translate brain activity into commands for machines are mainly used for medical reasons. For instance, someone with a limb amputation can use a BCI to control a prosthetic with their mind, while individuals with paralysis can use it to “type” words on a computer screen just by thinking about them. However, non-medical applications of BCIs are being explored, such as controlling smartphones with thoughts or even enhancing intelligence by “merging with AI.”

Graphene sensor enables mind to control robots

Evolving Technology

One of the challenges of developing BCIs is the difficulty of reading brain signals without invasive techniques such as implanting tech into the skull. Another challenge is the use of external “wet” sensors, which are covered in gels that can cause skin irritation and have a time limit on how long they can be used. The UTS researchers overcame these limitations by combining the best of graphene, which is very biocompatible and conductive, with the best of silicon technology, making the biosensor very resilient and robust to use.

To test their dry sensors, the researchers built them into a BCI with an augmented reality headset that displayed multiple squares of light, each linked to one of six different commands for a robot dog. The wearer could issue a certain command by concentrating on the corresponding square, and the dry sensors behind their ear read their brain activity and sent the order to the robot dog. The researchers collaborated with the Australian Army to demonstrate the system, and the correct command was issued with an average accuracy of 94%.

The dry sensors were not as accurate as wet ones, but the difference was small enough that the researchers believe the tech would be able to mostly close the gap with more precise sensor placement and pressure in a headset. The potential for this technology is broad and could be implemented in various systems by translating brain waves into zeros and ones. This breakthrough brings us a step closer to noninvasive BCIs for many applications, both on and off the battlefield.

WhatsApp’s New Audio Call Bar Feature Simplifies Calling Experience

Published

on

Whatsapp new audio call bar feature released.

Digital platforms like WhatsApp work hard to improve user experience. Meta, WhatsApp’s parent company, has introduced a new feature to enhance calling. Let’s explore this addition and how it helps users.

New Whatsapp Feature:

WhatsApp’s latest feature is the Audio Call Bar feature. It aims to make calls easier for users. It’s first available to select users and will come to iOS soon.

How It Works:

When users make a call, they’ll see a new call bar. This design lets users do other things while on a call. Users can mute or end calls from the interface. When you start a call, you’ll see a new call bar at the top of the app. It stays there even if you switch to another app, making it easier to do other things while you’re on a call. You can also mute or end the call right from this bar, which saves you time and makes things simpler.

Meta’s Improvement:

Meta is committed to making WhatsApp better. They want to make it a top communication platform. It shows their aim to connect people through easy communication.

Seamless Communication:

WhatsApp’s aim is to make communicating easy. The new call bar is part of this. It keeps up their promise to help users communicate easily.

Other WhatsApp Latest Features:

Along with the call bar, there are other new whatsapp features. Apple users have passkeys for secure logins. WhatsApp’s AI assistant also does more now, like generating info and images. All these updates make using WhatsApp better.

Pakistan First Lunar mission

In a historic move that marks Pakistan’s debut in lunar exploration, the country’s first satellite mission named ICube Qamar was successfully launched aboard China’s Chang’e 6 mission from Hainan, China. This monumental event not only underscores the burgeoning space alliance between Pakistan and China but also signifies a pivotal moment in global lunar research efforts.

The Chang’e 6 mission, renowned for its ambitious goal to retrieve samples from the far side of the moon, took to the skies on a Long March-5 rocket from the Wenchang Space Launch Site. This mission is poised to carve a new chapter in lunar exploration by focusing on areas of the moon that have remained largely unexplored by previous missions.

Exploring the Moon’s Mysterious Far Side

China’s venture to explore the enigmatic far side of the moon showcases the nation’s advancing capabilities in space technology. The Chang’e 6 mission is designed to spend two days on the lunar surface, with plans to gather around 2 kilograms (4.4 lb) of lunar samples. These samples are anticipated to shed light on the moon’s composition and uncover secrets about its enigmatic past.

What sets this mission apart is its emphasis on collaboration. The integration of Pakistan’s ICube Qamar satellite into the mission exemplifies a global collaborative effort in the quest for lunar exploration. ICube Qamar, representing Pakistan’s inaugural venture into moon exploration, is poised to play an instrumental role in gathering data from the lunar surface, enhancing our collective understanding of the moon.

A Milestone of Collaboration

The mission’s successful launch has been greeted with widespread acclaim and enthusiasm, especially within Pakistan, where the Prime Minister has celebrated this achievement as a landmark moment for the country’s aspirations in space exploration. This event underscores the profound partnership between Pakistan and China in pushing the frontiers of space technology and exploration.

The Chang’e 6 mission, featuring payloads from various countries, serves as a testament to the spirit of international cooperation that fuels our exploration of the cosmos. Through shared resources, knowledge, and visions, nations are unlocking extraordinary possibilities in space exploration, paving the way to unravel the mysteries of our universe collectively.

Looking Ahead

The success of the Chang’e 6 mission, with Pakistan’s ICube Qamar onboard, heralds a new era of international cooperation in space exploration. It demonstrates the immense potential of collaborative missions in advancing human knowledge and pushing the boundaries of what is possible.

As we await the return of the Chang’e 6 probe with samples from the moon’s far side, we stand on the brink of new discoveries that could redefine our understanding of the moon and beyond. This mission is not just a triumph for Pakistan and China but a victory for the international community’s collective endeavor to explore the unknown frontiers of space
