Researchers in Singapore say they have found a way to charge gadgets worn by a person by tapping the human body as a medium for wireless power transmission. They say their technique draws power from one source, say a mobile phone kept in the person’s pocket and transfers it to other gadgets worn by the person. The team from the National University of Singapore’s (NUS) Department of Electrical and Computer Engineering said they developed this technique to address the body-shadowing issues encountered by wireless charging systems in a small indoor area.

In the system developed by the NUS team, each receiver and transmitter on the human body contains a chip that is used as a springboard to extend coverage over the entire body. A user needs to place the transmitter on a single power source, such as a smartwatch on their wrist and the system harnesses energy from the source to charge multiple wearables via a process called body-coupled power transmission. The user will only need to charge one device, which will then power the rest of the gadgets worn by them from that single source simultaneously.

Body shadowing, caused by the obstructive presence of the human body, can result in increased path loss in indoor wireless systems. Methods available today were unable to deliver sustainable power to charge wearables on the human body, the researchers said in a study published in the journal Nature Electronics, adding that instead of trying to send charge around the obstacle (human body), they used it as a conduit to harvest and transmit power.

The researchers also looked into ways to harvest energy from the environment. People are exposed to electromagnetic waves most of the time in a typical office or home environment, for example from a running laptop or other such devices. The team’s method allows the body to harvest this energy to power wearable devices, irrespective of their location on the human body.

This could mean that you charge a watch simply by wearing it someday, instead of having to power up all the small gadgets you’re toting around individually.

Government Eases Approval Process for FDI in Space Sector

Government Eases Approval Process for FDI in Space Sector

India will allow 100% foreign direct investment in the manufacture of satellite systems without official approval and eased the rules for launch vehicles, a government statement said, aiming for a greater share of the global space market.

India’s space ambitions got a boost when it became the first country to land a spacecraft near the unexplored south pole of the moon in August – and the fourth to achieve a soft landing – just days after a similar Russian mission failed.

The government said in a statement late on Wednesday that foreign companies could invest in the manufacture of components and systems or sub-systems for satellites up to 100% without approval.

Foreign firms planning to build satellites in India would not require government approval up to 74% of the investment; for investment in launch vehicles, investment could go up to 49% without such approval, the statement said.

India has privatised space launches and is aiming for a five-fold increase in its share of the global launch market, which some expect to be worth $47.3 billion by 2032. India currently accounts for about 2% of the space economy.

The country hopes that liberalised rules for the space sector, long controlled by the government, will draw interest from Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin, among others.

The foreign direct investment policy reform is expected to boost employment and will allow companies to set up manufacturing facilities in India, the government said in the statement.

“This will give India access to the latest tech advances and much-needed funds, not only from the country but from international investors too,” said A.K. Bhatt, director general of the Indian Space Association.

Space-related India stocks such as Paras Defence and Space Technologies , MTAR Technologies, Taneja Aerospace and Aviation and Apollo Micro Systems climbed 2% to 5% on Thursday.

Neuralink Switches Location From Delaware to Nevada

Neuralink Switches Location From Delaware to Nevada

Elon Musk‘s brain-chip implant company, Neuralink, changed its location of incorporation from Delaware to Nevada, according to the business portals of both states.

The development comes about a week after Musk said Tesla would hold a shareholder vote to transfer its state of incorporation to Texas from Delaware after a judge invalidated his $56 billion (roughly Rs. 4,64,880 crore) pay package.

However, switching the state of incorporation for Tesla could come with hurdles such as investor lawsuits, particularly if it was seen as a move to secure his pay package, legal experts said.

Musk said last week that Neuralink had implanted its first brain chip in a human patient, who was recovering well after the procedure.

Neuralink did not immediately respond to a Reuters request for comment.

In September 2023, the company received approval from an independent review board to begin recruitment for the first human trial of its brain implant for paralysis patients.

Those with paralysis due to cervical spinal cord injury or amyotrophic lateral sclerosis may qualify for the study, it said but did not reveal how many participants would be enrolled in the trial, which will take about six years to complete.

The study will use a robot to surgically place a brain-computer interface (BCI) implant in a region of the brain that controls the intention to move, Neuralink said, adding that its initial goal is to enable people to control a computer cursor or keyboard using their thoughts alone.

Elon Musk’s Neuralink Installs Brain Implant in Human for the First Time

Neuralink, the California-based neurotechnology company, has implanted a wireless brain chip in a human for the first time, revealed co-founder Elon Musk. The big development was revealed by Musk on January 29 via a series of posts on X (formerly known as Twitter). Neuralink has been working on creating implantable brain-computer interfaces (BCIs). Last year in May, the company received approval from the US Food and Drug Administration (FDA) to conduct human trials. In September 2023, the neurotechnology firm began its human trial recruitment.

Announcing in a post, Musk said, “The first human received an implant from Neuralink yesterday and is recovering well. Initial results show promising neuron spike detection.” He also revealed separately that the first BCI product by the company had been named Telepathy. The brain chip enables the control of a computer or a smartphone just by thinking, claimed the co-founder. Interestingly, the company posted a video on YouTube in 2021 where a monkey could be seen controlling a game of ping-pong with his mind, after being implanted with the chip.

“Imagine if Stephen Hawking could communicate faster than a speed typist or auctioneer. That is the goal,” he added. The first users of the product will be those who have lost the use of their limbs.

While Neuralink received its FDA approval to conduct human trials last year, it rejected an application to pursue the same in 2022. At the time, the regulatory body had cited major safety concerns involving “the device’s lithium battery; the potential for the implant’s tiny wires to migrate to other areas of the brain; and questions over whether and how the device can be removed without damaging brain tissue,” as per a report by Reuters.

In a 2019 presentation, Musk explained that Neuralink BCIs were composed mostly of polyimide alongside a thin gold or platinum conductor. These were inserted into the brain through an automated process performed by a surgical robot. The chip contains a high number of ultra-thin nodules with wires called probes. The endings of these probes contain electrodes that are capable of locating and reading electrical signals in brain. These signals are then wirelessly transmitted to a device which can convert it into electronic commands to control a device.

In the past, the company has conducted extensive tests on animals and has claimed a high success rate. While performing a successful brain chip implant is a major milestone, the success of the product will be determined by its long-term performance and lack of side effects.
