New Electronic Device Developed to Help Mute People Talk

Two Chinese researchers have created a prototype device that can be taped to the skin to measure the motions and vibrations of the vocal cords and transform them into sounds.

The researchers also improved the device so it becomes thinner and lighter, so when attached to the neck like a temporary tattoo, it doesn't cause the wearer any discomfort, the German News Agency reported.

According to the ACS Nano journal, speech is actually a complex process that involves both motions of the mouth and vibrations of folded tissues, called vocal cords, within the throat. If the vocal cords sustain injuries or other lesions, a person can lose the ability to speak.

Researchers He Tian, Yi Yang, Tian-Ling Ren and colleagues used graphene on a thin sheet of polyvinyl alcohol film. The flexible device measured 0.6 by 1.2 inches, or about double the size of a person's thumbnail.

The researchers used water to attach the film to the skin over a volunteer's throat and connected it with electrodes to a small armband that contained a circuit board, microcomputer, power amplifier and decoder.

The Science Daily website reported that the instrument converts the throat's movements into emitted sounds, such as the words "OK" and "No."

The researchers say that, in the future, mute people could be trained to generate signals with their throats that the device would translate into speech.

The top bidder at a Tokyo fish market said they paid $1.3 million for a tuna on Sunday, the second highest price ever paid at an annual prestigious new year auction.

Michelin-starred sushi restauranteurs the Onodera Group said they paid 207 million yen for the 276-kilogram (608 pound) bluefin tuna, roughly the size and weight of a motorbike.

It is the second highest price paid at the opening auction of the year in Tokyo's main fish market since comparable data started being collected in 1999.

The powerful buyers have now paid the top price for five years straight -- winning bragging rights and a lucrative frenzy of media attention in Japan.

"The first tuna is something meant to bring in good fortune," Onodera official Shinji Nagao told reporters after the auction. "Our wish is that people will eat this and have a wonderful year."

The Onodera Group paid 114 million yen for the top tuna last year.

But the highest ever auction price was 333.6 million yen for a 278-kilogram bluefin in 2019, as the fish market was moved from its traditional Tsukiji area to a modern facility in nearby Toyosu.

The record bid was made by self-proclaimed "Tuna King" Kiyoshi Kimura, who operates the Sushi Zanmai national restaurant chain.

During the Covid-19 pandemic the new year tunas commanded only a fraction of their usual top prices, as the public were discouraged from dining out and restaurants had limited operations.
