Wireless Controlled from the Cloud

March 22, 2010

IBM researchers in China believe that shifting the signal-processing requirements for cellular phone networks from traditional expensive base stations into the cloud will make it cheaper and easier to upgrade networks.

Intel could include wireless charging technology in select ultrabooks and smartphones beginning in the second half of 2013, according to a report from Digitimes.

It will use an ultrabook as the power source paired with related software and a transmitter to wirelessly charge a smartphone.

Samsung is also expected to launch a resonance wireless smartphone charger by 2013.

The report did not specify… read more

Wireless brain stimulation with magnetic nanoparticles

March 15, 2015

MIT researchers have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles to treat neurological diseases such as Parkinson’s disease.

Currently, brain stimulation uses pulses of electricity and requires a surgically implanted electrode wired to a power source outside the brain.

In their study, the team injected magnetic iron oxide particles 22 nanometers in diameter into the brain.… read more

Wireless brain sensor-transmitter could unchain neuroscience from cables

December 8, 2014

head-mounted transmitter

A team of scientists led by Brown University has developed a high-data-rate, low-power, wireless brain-sensor and transmitter system for acquiring high-fidelity neural data during animal behavior experiments.

The new system solves a fundamental problem in neuroscience research: cables, which are needed to connect brain sensors to computers, constrain movement of subjects, limiting the kinds of research that are possible.

“We view this as a platform device for tapping… read more

Wireless at the speed of plasma

December 14, 2010

A new antenna, called a Plasma Silicon Antenna, or PSiAN,  promises superfast wireless networks.

It consists of thousands of diodes on a silicon chip. When activated, each diode generates a cloud of electrons — the plasma — about 0.1 millimeters across. At a high enough electron density, each cloud reflects high-frequency radio waves. By selectively activating diodes, the shape of the reflecting area can be changed to focus and… read more

Wireless at Fiber Speeds

October 6, 2008

Battelle has demonstrated 20-gigabit-per-second wireless transmission in the lab, using 60 to 100 gigahertz signals.

The technique could be used to send huge files across college campuses, to quickly set up emergency networks in a disaster, and even to stream uncompressed high-definition video from a computer or set-top box to a display.

Wireless artificial heart implanted

July 3, 2001

University of Louisville surgeons made medical history yesterday, cutting a damaged heart out of the chest of a terminally ill patient and replacing it with an artificial pump that has no wires to the outside world, according to a unconfirmed report.

The plastic-and-metal heart, called the AbioCor, uses an implanted battery that powers the motor. It recharges from a coil that transfers energy through the skin.

Wired to the Brain of a Rat, a Robot Takes On the World

May 15, 2003

Georgia Tech researchers have created a hybrid mechanical/biological robot controlled by the neural activity of rat brain cells grown in a dish.

The neural signals are analyzed by a computer that looks for patterns emitted by the brain cells and then translates those patterns into robotic movement, providing real-world feedback to the neuron.

Wired textiles for a phone as useful as the shirt on your back

The director of the ElectroScience Laboratory at Ohio State University is trying to end the need for cellphone hardware like the Bluetooth earpiece by fabricating communication devices out of something that most states require we carry with us all the time anyway: clothing.

His effort is part of a broad technological effort to make “smart textiles”: wearable fabrics with embedded electronics that can collect, store, send and receive information.

‘Wired microbes’ generate electricity from sewage

September 19, 2013


Interdisciplinary team creates ‘microbial battery’ driven by naturally occurring bacteria that evolved to produce electricity as they digest organic material.

Engineers at Stanford University have devised a new way to generate electricity from sewage using naturally occurring “wired microbes” as mini power plants that produce electricity as they digest plant and animal waste.

Wired M.D.

September 9, 2004

Imagine a computer chip that can diagnose thousands of diseases from a single drop of blood, or detect any possible chemical or biological hazard.

Peidong Yang, a chemistry professor at the University of California Berkeley has grown exceptionally long, flexible nanowires from the same materials used in computer chips, like silicon and gallium nitride.

“Because of the unique dimension of these nanowires — thin and very long –… read more

Wipe out a single memory

March 15, 2007

A single, specific memory has been wiped from the brains of rats, leaving other recollections intact, using a drug known to cause limited amnesia (U0126).

Greg Quirk, a neurophysiologist from the Ponce School of Medicine in Puerto Rico, thinks that psychiatrists working to treat patients with conditions such as PTSD will be encouraged by the step forward. “These drugs would be adjuncts to therapy,” he says. “This is the… read more

Winning ways

February 7, 2007

Supercomputer programs like IBM’s Deep Blue have demonstrated their ability to outthink human chess players. There is one game, however, where humans still reign supreme: Go. Yet here too their grip is beginning to loosen.

MoGo, a program developed by researchers from the University of Paris, has even beaten a couple of strong human players, using the Monte Carlo method, a form of statistical sampling. It is ranked 2,323rd… read more
