RFIDs desenvolvidos pela Hitachi, com 0,005 mm quadrados… na foto da direita, ao lado de um fio de cabelo… Estão chamando de RFID Powder (talco de RFID)

Hitachi’s new RFID chips (pictured on right, next to a human hair) are 64 times smaller than their mu-chips (left)

Há previsão de comercialização destes em 2 ou 3 anos.

outros dados do artigo:

  • capacidade de 12-Bit ROM = ID único de 38 dígitos
  • Mu-chips: 0,4 x 0,4 mm
  • utilidades em papel-moeda, certificados, identificações
  • com essas novas dimensões, outras utilidades serão pensadas
  • medicine, pollution control, portability, etc.

transcrição do artigo original:

RFID keeps getting smaller. On February 13, Hitachi unveiled a tiny, new “powder” type RFID chip measuring 0.05 x 0.05 mm — the smallest yet — which they aim to begin marketing in 2 to 3 years.

By relying on semiconductor miniaturization technology and using electron beams to write data on the chip substrates, Hitachi was able to create RFID chips 64 times smaller than their currently available 0.4 x 0.4 mm mu-chips. Like mu-chips, which have been used as an anti-counterfeit measure in admission tickets, the new chips have a 128-bit ROM for storing a unique 38-digit ID number.

The new chips are also 9 times smaller than the prototype chips Hitachi unveiled last year, which measure 0.15 x 0.15 mm.

At 5 microns thick, the RFID chips can more easily be embedded in sheets of paper, meaning they can be used in paper currency, gift certificates and identification. But since existing tags are already small enough to embed in paper, it leads one to wonder what new applications the developers have in mind.

    A paper describing these chips was presented at ISSCC 2007 on Feb. 14 in San Francisco. Here’s an abstract of what was submitted (PDF):

    A 0.05×0.05mm2 RFID Chip with Easily Scaled-Down ID-Memory

    An ultra-small RFID chip uses an electron beam for writing 1T memory cells. A 90nm SOI CMOS process and double-surface electrode chip structures enable the design of 0.05×0.05mm2 and 5µm-thick RFID chips with small, low-cost and highly-reliable 128b ID-memory. The chip is verified at a carrier frequency of 2.45GHz with measured communication distance of 300mm.

    Doesn’t say anything about the antennas, but if they are like the Mu-Chips, they use external antennas that are much larger than the chips…

    Wow, i didnt think that I would actually live to see the mark of the beast appear. But hmmm, guess I did. Kinda same thing as
    neatoooo, i am positive this will not affect me as i will not get it..

    And where is the actual source for this news? I can’t find these chips on hitachi news and the rest of the sites that mention it trackback to here.

    […] Esta tecnología se está aplicando no sólo para la industria o el comercio, sino para utilidades cada vez más insospechadas: pulseras para gimnasios que te identifican y reconocen tu plan personal de ejercicios, frigoríficos que detectan los alimentos en su interior por su mera presencia (ni siquiera les tienes que pasar el código de barras), tickets de metro, identificación de mascotas, identificación para carnets de conducir o pasaportes, seguimiento de hormigones y de cultivos agrícolas, papel moneda… cadenas comerciales como Wal-Mart ya lo utilizan, e incluso la NASA está enviando RFID tags al espacio y PRADA utiliza RFID para identificar a sus artículos y a sus clientes!! No creáis que os queda muy lejos: Correos acaba de anunciar la implantación de su Plan Mercurio para hacer seguimiento de los envíos postales con localizadores mediante RFID, lo que os permitirá seguir la posición de cada uno de vuestros envíos por sms o directamente en su web… Lo realmente sorprendente es el nuevo invento de Hitachi: el Polvo de Radiofrecuencia, que son chips RFID minúsculos (0,05 x 0,05 mm) capaces de almacenar 38 dígitos de identificación. Es decir: os podéis encontrar un chip RFID escondido en cualquier objeto, alimento…. de manera imperceptible, con las grandes posibilidades de desarrollo que esto conlleva. […]

    This is so out of date. This chip was the typcial Japanese attempt to come up with their own standard and blow off the rest of the world.

    Some facts

    – ALL the new generations of RFID chips are tiny

    – You can’t possibly make money with electron beam writing on chips that have to sell for about a nickle (just the silicon). RFID tags of this class cost about 20 cents, and most of that is the package and the antenna

    – The small size becomes self defeating at some point – you still have to saw the wafer, and at some point, all you have is saw lanes (yes, I know you can cut the wafer with a laser)

    – The size of the chip has nothing to do with the tag – you still have to have an antenna – at least the size of a dime for this class of chip, unless you are willing to read it from only an inch away (some really small tags can’t even read at an inch)/

    – The reason you can’t find this on the company’s web site may have something to do with the fact that no serious customer wants to buy a tag that is not compliant to open standards.
