New Wireless Sensor Detects Physiological Signals Emanating from the Skin

Using metallic ink, researchers screen-print an antenna and sensor onto a stretchable sticker designed to adhere to skin and track pulse and other health indicators, and beam these readings to a receiver on a person’s clothing.

(Image credit: Bao Lab) Engineers at Stanford University have developed a method to identify physiological signals arising from the skin with the help of sensors that stick like Band-Aids and beam wireless readings to a receiver fixed onto clothing.

In order to illustrate this wearable technology, the scientists fixed sensors to the abdomen and wrist of a test subject to track the pulse and respiration of the person by detecting the way the skin stretches and contracts with each breath or heartbeat.

Similarly, stickers fixed to the knees and elbows of the person monitored movements of the arms and legs by determining the slight relaxation or tightening of the skin whenever the corresponding muscle flexed.

According to Zhenan Bao, the chemical engineering professor whose laboratory elucidated the system in an article published in Nature Electronics on August 15th, 2019, the new wearable technology—which the team refers to as BodyNet—will be initially utilized in medical environments like monitoring patients suffering from heart conditions or sleep disorders.

When an ID card is held up to an RFID receiver, an antenna within the ID card harvests a small amount of RFID energy from the receiver, then utilizes this to produce a code, and finally beams it back to the receiver.

To accomplish this task, they screen-printed metallic ink on a rubber sticker, but each time the antenna stretched or bent, those movements rendered its signal unstable or too weak to be useful.

NetsDaily Off-Season Report - No. 16

The Nets, once seen as the woeful little brother in New York, are sold in the biggest transaction in U.S. pro sports history, with a price tag more than one billion dollars higher than the next biggest deal!

Why it’s the most momentous week in Nets history since, well, the first week in July when the Nets acquired two of the league’s 10 best players, including perhaps its best player!

On September 23, 2009, in a bit of a surprise, Bruce Ratner agreed to sell control of the team and a piece of the yet unbuilt Barclays Center to the Russian oligarch who was then the richest man in Russia and the richest owner in sports.

A quarter of the team’s non-basketball staff had been laid off and the rest were forced to take “Friday furloughs,” an unpaid day off each week.

Moreover, the team played in the worst venue in professional sports, voted so annually in Sports Business Journal’s survey, and the vaunted move to Brooklyn was stuck in the courts.

In the meantime, the Nets challenged league records for futility, losing the first 18 games of the 2009-10 season and barely escaping the record for most losses in a season, going 12-70.

Jay-Z, the legend who Ratner had recruited to help the move, stopped going to games, his courtside seats empty or filled by lesser lights.

He was young, then in his late 40’s, and had a rogue past that included being detained by French police for bringing 20 young women to his Alpine retreat by charter jet from Russia.

The mining mogul agreed to buy 80 percent of the team and 45 percent of the arena for $223 million in cash (the first tranche of “good faith” money —$40 million— arriving in October 2009) plus agreements to cover $160 million in team debt and provide $60 million to cover basketball operations.

The bachelor billionaire (whose fortune at that point was estimated at between $18 billion and $25 billion) even promised to get married if he didn’t succeed.

People also tend to forget this was an era of good feelings between Russian and the U.S. The day of the agreement in September 2009, then Russian President Dmitry Medvedev was in New York for the UN General Assembly and took U.S. President Barack Obama aside at a function to let him in on the deal, asking for assurances that things would go well.

On “60 Minutes,” he claimed he didn’t know the whereabouts of his $50 million yacht Solemar, showed off an AK-47 that he said had been presented him by the Spetnaz, Russia’s version of the SEALS, for an unspecified favor.

He was “The Most Interesting Man in the World.” He even ran for President of Russia against Vladimir Putin and got 8.8 percent of the vote (25 percent in his hometown of Moscow.) Many saw the presidential foray as a farce, that he was set up as a phony liberal alternative to Putin ...

Later, Prokhorov called the Knicks owner “the little man.” When his GM couldn’t get a deal done on Carmelo Anthony, he referred to Melo as “Carmela” and ordered Billy King to “hereby” stop negotiating with the Nuggets.

More importantly, he spent a lot of his vast fortune on the team as it transitioned to Brooklyn, financing part of the arena construction, re-signing Williams to a $100 million deal (that he would later regret), trading for Joe Johnson and his massive contract, then finally greenlighting what ultimately was perceived as the worst trade in NBA history, trading for three long past their prime stars in Paul Pierce, Kevin Garnett and Jason Terry for a king’s ransom (pun intended) of draft picks and swaps.

In Russia, he tried to parlay his now high profile into running for mayor of Moscow but Putin’s allies changed the law to prohibit those with foreign investments from running.

When his media outlet, the Russian Business Channel, began investigating how Russian trolls were involved in US election meddling and how Putin’s daughter was engaged in money-laundering, his Moscow offices were raided ...

and more confused, Prokhorov claimed he had not offered Marks the job, jokingly (?) telling reporters, “I have never heard this name before.” The very next day, after 36 draining hours of offers and rumors and feigned ignorance, Marks had the job and the rest is history.

He didn’t pass blame on to his underlings, not Razumov, who had played a big role in the Boston trade, not Yormark who despite his marketing genius never delivered him a profit on the team.

Still, if the measure of a manager —or owner or “governor”— is leaving an organization better than when you found it, Prokhorov’s tenure was a huge success.

Compared to the other owners of New York pro sports teams, who are universally bland or worse, they were young, with a love of risk, quick wits and yes, a commitment to excellence.

That start-up became Alibaba, the Chinese e-commerce giant and the primary source of his net worth (which is now rivaled by his investment in sports.) There’s no personal scandal, no jet-skiing videos.

Its AliSports encompasses television and digital sports rights, event operation, venue commercialization, copyright, media, business development, gaming, and ticketing.

2 to Ma, became one of the world’s wealthiest people, with a current net worth hovering around $10 billion, the same as Mikhail Prokhorov, according to those who track such things.

He is a go-to commentator for western media looking for a voice to defend China in its ongoing trade war with the U.S. Tsai has warned that a full-blown trade war between the countries would hurt many U.S. businesses that have ties to China ...

Most recently, Reuters reported that Alibaba was the “force” behind a Chinese government propaganda app called “Xuexi Qiangguo,” which is required reading for Communist party cadre.

China’s rise as an economic power and its importance to world stability is too important for there to be a singular thesis.” Tsai may be critical of the current U.S. administration —and generally approving of the Chinese regime— but he and his American wife, Clara Wu Tsai, are very much woven into the fabric of American life.

In addition to their education —he at Yale, she at Stanford and Harvard — and their choice of domicile —La Jolla, their children are being educated in the U.S. and they have given generously to their alma maters through the Joe and Clara Tsai Foundation.

“Over the years I’ve come to learn it’s very difficult to move the needle on economic mobility, particularly in urban areas like Brooklyn, without also addressing the problems latent within our criminal justice system.” And basketball is only one of the sports the family cares about.

And of course, he’s owner of the New York Liberty buying full control of the team from James Dolan earlier this year, only a few months after agreeing to buy a minority stake in the Nets.

He’s called himself Lin’s “biggest fan” and a “very good friend.” The friendship —which extended to Tsai playing in Lin’s charity basketball game in China— survived the trade that sent Lin to Atlanta.

The night of the trade Tsai tweeted that Marks had made him aware of the trade talks and praised the GM for “doing terrific work to build the Nets for the long term.” Now, with the Nets, Barclays and Liberty making up a significant part of his net worth and his other charity work taking up significant chunks of time, Tsai will start to step back from his responsibilities at Alibaba.

There are rumors he’d like to parlay his sports ownership into a more high profile role on the international stage, but that doesn’t always work out as planned.
