Communication & Charging Made Possible by Simply Holding the Cellular Phone!? 《Slim, Thin, Bendable》Next Generation NFC "Spiral Antenna" Technology by RICOH Co., Ltd.

  • Other Products Deadline : Jan 31,2019
  • NFC technology (Near Field Communication) is used in many situations, such as payment of mobile wallet and electronic money. Conventionally, the parts of "NFC antenna" required for this communication had limitations in the range of introduction due to size reasons. Therefore, RICOH developed "RICOH Spiral Antenna" with the characteristic of being delicate, thin, and able to bend. The change has made previously difficult ideas possible.
    What's better, the technology can be utilized for wireless charge not only communication, it may be able to reduce the charging stress of various items.

What is NFC?

In short, NFC (Near Field Communication: Near Field Communication Standard) is a standard for "holding communication".

When devices with IC chips of this communication standard are brought close to within 10 cm, both sides can recognize and exchange information, functions such as mobile wallet, exchanging data between devices, personal authentication, etc. It is a technology supporting various situations in our daily life.

NFC is a mechanism in which "module" holding data with IC chip embedded and external terminals called "reader / writer" communicate data via "NFC antenna" included in each.

However, the NFC antenna, which is the key component of this NFC technology, had the following problems and the subjects to be introduced were restricted.

  • By reason of size and shape, equipment that can be introduced is limited
  • It interferes with metal
  • A single directivity

Therefore, Ricoh's research team worked on this subject and created a new "NFC antenna" called "RICOH Spiral Antenna" which is the providing technology of this time.

Let's see that feature.

It is resistant to metal disturbance and easy to read from multiple directions

In the conventional "NFC antenna", due to the influence of the internal metallic parts etc., there was a case that an event that radio waves were hard to read from a certain direction.

On the other hand, "RICOH Spiral Antenna" is resistant to metal disturbance due to its magnetic field characteristics, making it easier to read communication from multiple directions, and it is expected to be used in a wider range of scenes.

RICOH Spiral Antenna can be used for wireless charging

For example, when adding both functions of "mobile wallet" and "wireless charging" to a ring-shaped device, each antenna must be incorporated so far, securing a space within a small enclosure becomes a major issue when designing this 2-funtioned product.

"RICOH Spiral Antenna" can be used not only for NFC communication but also for "wireless charging antenna" and can also benefit from space saving within a small enclosure such as a ring type device, for example.

 

However, there is a limit to the charging ability of the small "RICOH Spiral Antenna".

For example, charging the newest model smartphone may take several days.

Please contact us if you have a concrete product image in mind, we welcome any of your creative ideas/proposals.

Application Ideas

We suggest some ideas about innovative "RICOH Spiral Antenna" on the following aspects:

• Wearable terminals (smart ring, smart wrist band, etc.)

• Hearing aid

• Earphone, headphones

• Toys

• Games

This time, by utilizing this technology, from "product concept" of "what kind of customer", "what kind of needs" and "how to satisfy" to "product design" such as shape / color and package, we are looking for a TOTAL, COMPLETE product planning proposal!

 

* If the design work is difficult, suggestions of only "product concept" are also acceptable.

About the design proposal competition!

• Process until commercialization

The deadline for the product planning (concept · design) is January 31, 2019.

• Briefing sessions!

We will hold a briefing session on RICOH's technology, expect detailed explanation from RICOH's researchers on Wednesday, December 12 at 18:30 in Shibuya. We are looking forward to your active questions.
