nanoe
Nano-sized electrostatic atomized water particle, nanoe™, that improves air quality
What electrostatic atomized water particle, nanoe™,can do
Panasonic has developed technology for producing nano-sized electrostatic atomized water particle, nanoe™, that improves air quality and changes our living.
Experiments have proven a long list of the benefits of “electrostatic atomized water particle,” generated by cutting-edge nanotechnology.
What is the nano-sized electrostatic atomized water particle?
"The electrostatic atomized water technology" is generating nano-sized water particles by gathering invisible moisture in the air and by applying high voltage.
These electrified water particles are called "electrostatic atomized water" and contain highly reactive components that easily affect wide variety of substances. This particle can inhibit virus and bacteria; and reduces pesticides.
Generally, highly reactive components tend to react with other substances easily and have short life.However the reactive components generated by "the electrostatic atmized water technology" are wrapped and contained in the water particle.
Hence, it has been proved that the substances have a longer life and are delivered to wider areas than usual ions.

Mechanism of producing electrostatic atomized water particles
Safety of nanoe™
Panasonic has confirmed the safety of nano.
nanoeTM is micro-particle ions wrapped by water. It is safe because it consists of moisture in the nature. The following safety test data have been obtained.

Proven benefits of electrostatic atomized water particles,nanoe™,through experiments
Experiments have newly proven that nanoe suppress Swine-origin influenza virus. The benefits range widely from inhibiting viruses and bacteria, reducing residue pesticides, suppressing mold and allergen, moisturizing skin and hair, and to maintaining vegetable freshness.
Experiments by universities and research institutions have proven the effects of nanoe. The world is focusing its attention on this breakthrough technology that could be the key to the air purification.

nanoe™ Story
Exploring the Unknown Frontier of Nanotechnology
Let’s take a look back on how this technology was developed. The electrostatic atomized water is in the unknown frontier of nanotechnology, then in order to prove its benefits, it was necessary to develop experimentation and evaluation methodologies from scratch.
The research originally grew out of a project Panasonic involved, led by the Japanese Ministry of International Trade and Industry (MITI; now METI). The project was started in 1997 for the development of technology for measuring nano-sized particles. At that time, Toshiyuki Yamauchi and his fellow researchers at Panasonic were exploring odor removal technology, such as removing the smell of tobacco from curtains, when they became aware of a research of Professor Kikuo Okuyama of Hiroshima University on how to refine electrostatic atomized water. By 2001, researchers from Panasonic had joined forces with Professor Okuyama to initiate joint research to develop a device for producing electrostatic atomized water particles.
Research at Panasonic was started by Yamauchi and a junior colleague. The pair struggled to prove the benefits of electrostatic atomized water, but there was no validation method at that time. The research team was close to being forced to abandon the technology, since they could not persuade the company’s business departments to commercialize the technology. “In spite of our struggles, the head of our research lab at the time decided that we would work on the project for one more year, enabling us to continue the R&D,” says Yamauchi.
The technology was kept alive by the dedication and attraction to technology that has always been a hallmark of Panasonic. On the other hand, there are still so many unknowns about nanotechnology. Researchers at Panasonic, in collaboration with researchers at universities and research institutions, are continuing to explore the benefits of this technology by developing new hypotheses, building up the validation methods for them, and thus proving the technology's benefits.

Corporate Engineering Division Appliance Company
Panasonic Corporation
Dedication, Discovery and Refinement
Panasonic was founded with a manufacturing philosophy of exploring all possibilities for business, work and products.There is a saying that “once dug deep into the vein, a well never dries out” and this continues to be symbolized by the company today.
The electrostatic atomized water technology is a good example of this philosophy, because it was discovered through Panasonic. tireless efforts to improve air quality. As the researchers dug on the technology well, more and more benefits had been revealed from the well, and today, the technology has become essential for improving air quality.
“Electrostatic atomized water, which continuously purifies air, has the potential to become an indispensable part of our lives,” says Shosuke Akisada of the Beauty and Living Business Unit, Appliance Company, in charge of business development. “We want this technology to be incorporated into all kinds of our products.”
Panasonic has reduced the size of the devices and improved performance so that the devices can be used in everywhere, and has filed approximately 300 patent applications in relation to the technology. The dedication and persistent pursuit of the engineers at Panasonic is steadily bringing the technology closer to the company’s vision.

Improving the Quality of the Air Worldwide
Panasonic electrostatic atomized water creates various new values. “I am convinced that this technology will change the way we live and improve the quality of life all around the world,” says Yamauchi.
The applications for the technology are huge as it can be applied to any place where there is an air. Panasonic is determined to improve the quality of the air, and make the environment better for the people.
The need for air quality improvement is high, whether it is in public spaces or the home or office. The technology can be expected to be used in transport facilities such as cars, trains and airplanes, as well as in medical facilities. There is also universal interest in using the technology for health and beauty applications. Panasonic is actively pursuing a global strategy for the technology, seizing on its enormous potential to be accepted in the worldwide market.
The prospects for the technology are outstanding in not only mounting in a broad range of Panasonic Group products but also shipment as value adding devices to the product in various industries.
