Scientists introduced a device that creates holograms using ultrasound & polystyrene ball

Researchers at the University of Sussex in the UK have introduced technology that can create holograms using ultrasound and a 2mm polystyrene ball. They can move and interact with the observer.


Scientists called the new technology "multimodal acoustic trap display" (multimodal acoustic trap display, or MATD). Images are created between two horizontal plates on which many tiny ultrasound speakers are mounted. They create an inaudible sound field in which there is a "pocket" of low pressure, where a polystyrene ball enters. By moving the "pocket", you can move the ball, forming an image. Colors are added to the image using the projector.
Through careful monitoring of the ultrasound field, scientists can add sound effects and music to animated images. Vibrations can be adjusted to receive sound waves in the entire range of human hearing and, for example, to imitate clear speech. In addition, you can interact with images and even feel them in your own hands.

Why does Japan have high life expectancy? | Japan life expectancy reasons

In a world in which in the last sixty years the number of people 65 years of age or older (from 5 to 9%) has almost doubled, Japan holds the leadership.

The acceleration of aging here is more noticeable than in other places: more than a quarter of the population is 65 years of age or older. 

In Japan, the most advanced technologies have inspired the public and private sectors in health and innovation policies to ensure a better quality of life for the elderly.

An aging society is a serious challenge for the health system. The solutions offered by Japan centered an international summit in Tokyo that brought together medical experts from all over the world, public officials, start-ups, and foreign delegations.

The centerpiece of the Japanese strategy to establish a digital health care system has been the fusion of medical data and technology.

The German professor Erwin Bottinger, from the Hasso Plattner Institute, is one of the world's leading experts in digital healthcare innovation. "I am impressed by what is happening in Japan.

The benefits of digitalization, the benefits of Artificial Intelligence for our citizens, and our societies will be more excellent in the way we improve health, improve health in the distant future: but that requires that we have a good relationship with our data. "

Japan is establishing a new regulation to allow the public and private sectors to use anonymously processed medical data.

To see how this digital transition has been implemented, we have been in Kyoto, at the University Hospital. The collection of records begins in the patient's bedroom. Nurses transmit information such as blood pressure, heartbeat, body temperature, clinical tests, and treatments directly to the servers.

The processing of this vast data set outside of medical care, periodic controls and long-term care centers, allows to be more precise and efficient and obtain information on how to manage the health system to prevent diseases and boost the production of medicines.

"We collect data to understand what is happening in this country and what kind of medical treatment we provide to people. By using this data, we can see different treatments or care. We make these data anonymous, and the government prepares a system to share them with everyone. Through this system, the private sector can use the data to create new medications or treatments, "explains the director of Kyoto University Hospital, Tomohiro Kuroda.

Japanese health insurance depends on billions of data from more than 126 million citizens. A unique data set that could be a source of opportunities even outside the country.

Genta Kato, head of the center for solutions for the claim of health insurance, says that " more than 95% of care for the Japanese population based on data processing. There is a tendency to use data on medical treatment and care of nursing as a complete package for digital healthcare. Japan is a super-aged society, and I think our knowledge could be a reference for many other countries in the world. "

Japan is the second-largest market in the world in the health sector. The process of innovation in digital care has generated essential business opportunities for private medical companies in Japan. Sompo's 'Future Care Lab' project, for example, is developing cutting-edge technologies to address the needs of an aging society.

Products such as the AI ​​wheelchair, capable of moving autonomously, the convertible bed, and body sensors for the bathroom can help older people to live more independently.

Shinichiro Kataoka, head of the future care laboratory, explains: "Japan is an aging society and, by using technology, we can reduce the workload of caregivers and also improve the productivity of their work. For example, to minimize caregiver tasks, one of the solutions is the assisted bed. It allows reducing the burden and the number of caregivers to one person instead of two, who have to help patients with a lot of weight. "

Beyond high-tech solutions, the human factor remains important, as it can facilitate the interaction between the patient and the care device, or the person who takes care of it.

This is the case of the Virtual Reality headsets, developed by Silver Wood Corp. By simulating what it is to have dementia, it makes people understand the effects of that pathology and how to treat these types of patients.

"We do not want caregivers and patients to be divided, and we want to create a responsible relationship in which both need each other. This is content that reproduces the world precisely as perceived by patients with dementia. 

The fact that we, people without problems, we can experience it through Virtual Reality, it makes us understand the pain and difficulties of these people. Then, this technology allows us to feel all that for ourselves, "defends the president of the company, Tadamichi Shimogawara.

One of the caregivers working in this Tokyo nursing home appreciates the educational function of this device. "I felt I had learned a lot more about dementia than I could read in textbooks."

This combined approach to promote the use of cutting-edge data and technologies, to develop a next-generation health system, makes Japan a kind of open innovation ecosystem. Due to the global aging trend that can have a triggering effect on international cooperatives and companies, inspired by the large amount of high-quality medical data that Japan has.

"The success of this approach in Japan will be contagious and will motivate citizens to adopt the concept, so that throughout Europe, throughout the developed world and in the developing world, we have a unified approach: moving towards digital health," believes Professor Erwin Bottinger.

International collaboration will be vital to maximizing the potential of innovation in digital health and preparing a future society with a life expectancy of 100 years.
