Novak Djokovic has raised eyebrows at this year’s Grand Slams by revealing a mysterious metal disc strapped to his chest.
The tennis star had the coin-like device taped between his pectorals at the French Open and Wimbledon, and could wear it again when the US Open starts on Monday.
His first opponent is Alexandre Muller, as the Serb aims for a record-extending 24th Grand Slam men’s singles title.
The world number two sees the chest gadget as key to his success – so what is it?
‘Biggest secret of my career’
Djokovic was asked about the disc after his second round French Open win over Marton Fucsovics in May, after it caught the attention of bemused commentators and viewers.
“When I was a kid I liked Iron Man a lot,” he said, noting its resemblance to part of the Marvel superhero’s suit.
“So I try to impersonate Iron Man.”
Iron Man’s similarly-shaped chest device powers his robotic outfit, and is designed to prevent bullet shrapnel in his body from reaching his heart.

For Djokovic, no such problems. Instead, he said it’s all about enhancing his performance on the court.
“My team delivers incredibly efficient nanotechnology to help me deliver my best,” he said.
“That’s probably the biggest secret of my career. If it wasn’t for that, I probably wouldn’t be sitting here.”

What kind of ‘nanotechnology’ is this?
Following Djokovic’s comments, an Italian company called Tao Technologies said it was behind the device.
Described as a “human upgrade device”, the patented Taopatch is designed to improve health and wellbeing.
It claims the patch, which “uses two layers of nanocrystals that convert heat from your body into light”, sends therapeutic signals to the wearer’s nervous system to help their body achieve true balance.
Improved sleep, posture, balance, flexibility, recovery times, and focus, alongside reductions in stress, anxiety, and chronic pain, are among the benefits it purportedly provides.
The firm even claims the patch – which starts at £238 – has helped patients with multiple sclerosis.
Fabio Fontana, inventor of Taopatch and CEO of Tao Technologies, told Sky News he was inspired to invest in the product after becoming dependent on painkillers after a car accident.
“All the therapies I tried only provided temporary results,” he said.
“A doctor in Rome was the first to give me results with laser treatments. The benefits were significant in relieving the tension in the muscles of my neck and back, but its effectiveness lasted only a week.
“I wondered if it would be possible to create a kind of wearable laser to prolong the effect of the treatment.”
The nanocrystals, he said, simulate the effect of the laser treatments he received – and that the patch is simply “a different way of administering light therapy”.

Are the claimed benefits legitimate?
Tao says its patch is an approved medical device, according to EU regulations, however is yet to be approved by America’s drugs regulator.
The firm cites studies into its effectiveness on its website. One Italian study in 2021 concluded it improved balance, movement, and affected limbs of multiple sclerosis patients, while another that looked into its impact on athletic performance said it had improved participants’ grip and squat strength.
Mr Fontana also pointed to studies into the benefits of light therapy, and said the patch was available to all research institutions that wanted to conduct clinical trials.
But Tao’s claims have failed to move some experts.
In an article for Science-Based Medicine, Dr Harriet Hall said the company’s explanation “is not credible”.
Dr Brandon Beaber, a neurologist, has said studies may suggest a “little bit of benefit” anecdotally, but they remained unproven so far as multiple sclerosis treatment.
And Professor Edzard Ernst, of the University of Exeter, told Sky News none of the company’s claims seemed “supported by sound evidence”.
“The notion that it generates any benefit is bogus,” he said.
“The principles put forward fly in the face of science.”
Prof Ernst said any benefit gained by Djokovic would “entirely depend on a placebo response”.

Given Djokovic has not been banned from using the patch, tennis authorities also appear unconvinced it provides tangible advantages.
The ATP Tour and International Tennis Federation have not commented on its use – and you could be forgiven for having doubts given Djokovic’s previous health positions.
The 36-year-old famously refused to take a COVID vaccine, and missed several tournaments as a result due to international travel restrictions.
He’s also previously suggested he believes some people have telepathic powers, gave up gluten after claiming proximity to a piece of white bread made his body feel weaker, and said having an operation on his elbow in 2018 caused him to feel “like I had failed myself”.
As for the “biggest secret” of his career, it’s now out in the open.
Whether it makes any difference or not, he’ll no doubt be among the main contenders at the US Open between now and the tournament’s end on 10 September.

“Terrible”, “weird”, “peculiar” and “baffling” – some of the adjectives being levelled by observers at the Donald Trump administration’s peace plan for Ukraine.
The 28-point proposal was cooked up between Trump negotiator Steve Witkoff and Kremlin official Kirill Dmitriev without European and Ukrainian involvement.
It effectively dresses up Russian demands as a peace proposal. Demands first made by Russia at the high watermark of its invasion in 2022, before defeats forced it to retreat from much of Ukraine.

Ukrainian support for peace plan ‘very much in doubt’
The suspicion is Mr Witkoff and Mr Dmitriev conspired together to choose this moment to put even more pressure on the Ukrainian president.
Perversely, though, it may help him.
There has been universal condemnation and outrage in Kyiv at the Witkoff-Dmitriev plan. Rivals have little choice but to rally around the wartime Ukrainian leader as he faces such unreasonable demands.
The genesis of this plan is unclear.
Was it born from Donald Trump’s overinflated belief in his peacemaking abilities? His overrated Gaza ceasefire plan attracted lavish praise from world leaders, but now seems mired in deepening difficulty.
The fear is Mr Trump’s team are finding ways to allow him to walk away from this conflict altogether, blaming Ukrainian intransigence for the failure of his diplomacy.
Mr Trump has already ended financial support for Ukraine, acting as an arms dealer instead, selling weapons to Europe to pass on to the invaded democracy.
If he were to take away military intelligence support too, Ukraine would be blind to the kind of attacks that in recent days have killed scores of civilians.
Europe and Ukraine cannot reject the plan entirely and risk alienating Mr Trump.
They will play for time and hope against all the evidence he can still be persuaded to desert the Kremlin and put pressure on Vladimir Putin to end the war, rather than force Ukraine to surrender instead.
The Eurovision Song Contest is changing its voting system, following allegations of “interference” by Israel’s government this year.
Israeli singer Yuval Raphael received the largest number of votes from the public in the contest in May, ultimately finishing as runner-up after the jury votes were counted.
But a number of broadcasters raised concerns about Israel’s result.
After the final, Irish broadcaster RTE requested a breakdown in voting numbers from contest organiser the European Broadcasting Union (EBU), while Spain’s public broadcaster, Radio Television Espanola (RTVE), called for a “complete review” of the voting system to avoid “external interference”.
In September, Dutch public broadcaster AVROTROS said it could no longer justify Israel‘s participation in the contest, due to the Israel-Hamas war in Gaza.
It went on to say there had been “proven interference by the Israeli government during the last edition of the Song Contest, with the event being used as a political instrument”. The statement did not elaborate on the means of “interference”.
Sky News has contacted the Israeli government for comment.

In early December, the EBU will hold its winter general assembly, with members due to consider the changes, and if not satisfied, vote on Israel’s participation.
Key changes to next year’s competition include:
• Clearer rules around promotion of artists and their songs • Cap on audience voting halved • The return of professional juries to semi-finals • Enhanced security safeguards

Will Eurovision boycott Israel?
Sanctions threat
The EBU said the tightening of rules around promotion was to “discourage disproportionate promotion campaigns… particularly when undertaken or supported by third parties, including governments or governmental agencies”.
It said that “any attempts to unduly influence the results will lead to sanctions”.
Contest director Martin Green said “no broadcaster or artist may now directly engage with or support campaigns by third parties – including governments or their agencies – that could distort the vote”.
He said the reduction in the number of votes that can be made online, or via SMS or phone call, from 20 to 10 was “designed to encourage more balanced participation”.
He said that “although the number of votes previously allowed did not unduly influence the results of previous contests, there were concerns expressed by participating broadcasters and fans alike”.
Professional juries in semi-finals – and younger jurors
It was also announced that professional juries in the semi-finals would be restored for the first time since 2022, with an expansion to the range of professions from which jurors can be chosen.
The EBU said this will give roughly 50-50 percentage weight between audience and jury votes.
At least two jurors aged 18-25 will be present in every jury, to reflect the appeal of the contest with younger audiences.
Also mentioned were enhanced technical safeguards designed to “protect the contest from suspicious or coordinated voting activity” and strengthen security systems that “monitor, detect and prevent fraudulent patterns”.
Politics making itself heard over Europop lyrics
Mr Green said that the neutrality and integrity of the competition is of “paramount importance” to the EBU, its members, and audiences, adding that the event “should remain a neutral space and must not be instrumentalised”.

Russia was banned from the competition in 2022 following its invasion of Ukraine.
Israel has competed in Eurovision for more than 50 years and won four times, but there have been ongoing calls to block their participation over the conduct of Prime Minister Benjamin Netanyahu’s government in the Hamas-Israel war.
Israel denies targeting civilians in Gaza and has said it is being unfairly demonised abroad.
In September, Spain, the Netherlands, Ireland, Iceland, and Slovenia threatened to withdraw their participation in Eurovision unless Israel is excluded from the competition.
There were also demonstrations against Israel’s inclusion in Basel, Switzerland, when the 2025 competition took place.
‘Step in right direction’
Responding to the changes, Iceland’s official broadcaster RUV told Sky News they were “a step in the right direction”, and they would be discussing them with their “sister stations in the Nordic countries” ahead of the EBU meeting in December.
Ireland’s official broadcaster RTE told Sky News: “Clearly, events in the Middle East are unfolding day by day. As previously confirmed by the EBU, the issue of participation in the 2026 Eurovision Song Contest has been included on the agenda of the EBU Executive Board’s ordinary Winter General Assembly.”
Sky News has also contacted the official broadcaster for the Netherlands (AVROTROS), Spain (RTVE), Slovenia (RTVSLO), and Israel (Kan) for comment.
The chief executive of Kan, Golan Yochpaz, has previously said the event should not become political and that there is “no reason” why Israel should not be part of it.

Netanyahu praised Israeli entrant
Earlier this year, Israeli Prime Minister Benjamin Netanyahu told Israel’s 2025 Eurovision entrant Yuval Raphael she had brought the country “a lot of honour” after she finished in second place, adding “you’re the real winner. Statistically, it’s true… You entered the hearts of a huge portion of the public in Europe.”
The year before he told entrant Eden Golan: “I saw that you received almost the highest number of votes from the public and this is the most important thing, not from the judges but from the public, and you held Israel’s head up high in Europe.”
In October, a ceasefire deal was put in place, aimed at bringing an end to the two-year war in the Middle East.
The war began when Hamas stormed into Israel on October 7 2023, killing around 1,200 people and taking 251 hostage.
Israel invaded Gaza in retaliation, with airstrikes and ground assaults devastating much of the territory and killing more than 67,000, according to the Hamas-run health ministry.
Its figures do not differentiate between civilians and combatants, but it says around half of those killed were women and children.
The world’s largest live music event, next year’s contest will be held in Vienna, Austria, in May and will celebrate 70 years of Eurovision.
Over 200 students have been kidnapped from a Catholic boarding school in western Nigeria – the second mass abduction in the country this week.
Gunmen took 215 students and 12 teachers from St Mary’s School in Agwara, Niger state, early on Friday, according to the Christian Association of Nigeria.
Daniel Atori, a spokesperson for the Niger state chapter of the association, said he met parents of the abducted children “to assure them that we are working with the government and security agencies to see that our children are rescued and brought back safely”.
St Mary’s is a secondary school that has students aged 12 to 17, but the institution is attached to an adjoining primary school with more than 50 classrooms and dormitory buildings.
Dauda Chekula, 62, said that four of his grandchildren, ranging in age from seven to 10, were among those abducted.

“We don’t know what is happening now, because we have not heard anything since this morning,” Mr Chekula said.
“The children who were able to escape have scattered, some of them ran back to their houses and the only information we are getting is that the attackers are still moving with the remaining children into the bush.”
On Monday, 25 schoolgirls were kidnapped from a boarding school in neighbouring Kebbi state, northwest Nigeria.
Police said men armed with rifles stormed the Government Girls Comprehensive Secondary School in the town of Maga at around 4am local time (3am UK time), arriving on motorcycles in an apparently well-planned attack.
Student escapes from kidnappers
A 15-year-old student who was among those abducted from the boarding school in Kebbi state’s Danko-Wasagu area managed to escape.
She said she found refuge at a teacher’s house.

It was not immediately clear who was to blame for either of the abductions.
Abubakar Usman, the secretary to the Niger state government, said in a statement that the latest kidnapping occurred despite a prior intelligence warning of heightened threats.
“Regrettably, St Mary’s School proceeded to reopen and resume academic activities without notifying or seeking clearance from the state government, thereby exposing pupils and the staff to avoidable risk,” it read.
A security staffer was “badly shot” during the early-morning attack on the school, the Catholic Diocese of Kontagora said.

Ransom demand for worshippers
Separately, gunmen attacked a church in Kwara state on Monday, killing at least two people.
A church official said 38 worshippers were also kidnapped by the gunmen, who have since issued a ransom demand of 100 million naira (£52,660) for each person.

The attacks have highlighted insecurity in Nigeria and forced President Bola Tinubu to postpone foreign trips.
At least 1,500 students have been abducted in the region since Boko Haram extremists seized 276 Chibok schoolgirls more than a decade ago.
No group has claimed responsibility for the attacks in Niger and Kebbi state, but analysts say gangs often target schools in kidnappings for ransom.
Nigeria was recently thrust into the spotlight after Donald Trump singled the country out, claiming that Christians are being persecuted – an allegation that the government rejected.
