by means of a roll-on coating consisting of a honeycomb of electrodes (see bottom right image).

whereby opaque, charged particles (approx. 1 micron in size) are attracted to electrodes that posses an opposite charge.

Thus the electric field created between the two electrodes causes the flow of these particles back and forth.

The interaction of incoming light with each electrophoretic pixel (two electrodes) depends on the position of the particles relative to these electrodes,

In reference to these, the device uses electrophoresis to attract charged color particles to the top transparent electrode to preadtheir color,

which are adjacent to the electrode. The device is filled with dual-colour, dual-particle colloidal dispersion inks.

It is common in e-ink displays to use sub-pixels (i e. multiple electrodes to do some fancy charged transport),

They use three electrodes and by altering the applied voltages between them all, many color states are created during operation,

which is the same technology used to pattern microchips and is very expensive. But the design here can be integrated with HP roll-to-roll micro-patterning technique, a much cheaper and large scale alternative.

or support layer, of a computer chip, with cellulose nanofibril (CNF), a flexible, biodegradable material made from wood."

"The majority of material in a chip is support. We only use less than a couple of micrometers for everything else,

"Now the chips are so safe you can put them in the forest and fungus will degrade it.

CNF offers many benefits over current chip substrates, she says.""The advantage of CNF over other polymers is that it's a bio-based material and most other polymers are based petroleum polymers.

"The group's work also demonstrates a more environmentally friendly process that showed performance similar to existing chips.

The majority of today's wireless devices use gallium arsenide-based microwave chips due to their superior high-frequency operation and power handling capabilities.

"I've made 1, 500 gallium arsenide transistors in a 5-by-6 millimeter chip. Typically for a microwave chip that size,

#Scientists print low cost radio frequency antenna with graphene ink (Nanowerk News) Scientists have moved graphene--the incredibly strong and conductive single-atom-thick sheet of carbon--a significant step along the path

Researchers from the University of Manchester, together with BGT Materials Limited, a graphene manufacturer in the United kingdom, have printed a radio frequency antenna using compressed graphene ink.

The antenna performed well enough to make it practical for use in radio-frequency identification (RFID) tags and wireless sensors,

the antenna is flexible, environmentally friendly and could be cheaply mass-produced. The researchers present their results in the journal Applied Physics Letters,

Paving the Way to Antennas, Wireless Sensors, and More The researchers tested their compressed graphene laminate by printing a graphene antenna onto a piece of paper.

The antenna measured approximately 14 centimeters long, and 3. 5 millimeter across and radiated radio frequency power effectively,
