Reading Minds and Influencing Human Behavior With Neural Dust
By Robert Sanders
UC Berkeley engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time.

Because these batteryless sensors could also be used to stimulate nerves and muscles, the technology also opens the door to “electroceuticals” to treat disorders such as epilepsy or to stimulate the immune system or tamp down inflammation.
The so-called neural dust, which the team implanted in the muscles and peripheral nerves of rats, is unique in that ultrasound is used both to power and read out the measurements. Ultrasound technology is already well-developed for hospital use, and ultrasound vibrations can penetrate nearly anywhere in the body, unlike radio waves, the researchers say.
“I think the long-term prospects for neural dust are not only within nerves and the brain, but much broader,“ said Michel Maharbiz, an associate professor of electrical engineering and computer sciences and one of the study’s two main authors. “Having access to in-body telemetry has never been possible because there has been no way to put something super tiny super-deep. But now I can take a speck of nothing and park it next to a nerve or organ, your GI tract or a muscle, and read out the data.“

Maharbiz, neuroscientist Jose Carmena, a professor of electrical engineering and computer sciences and a member of the Helen Wills Neuroscience Institute, and their colleagues will report their findings in the August 3 issue of the journal Neuron.
The sensors, which the researchers have already shrunk to a 1 millimeter cube – about the size of a large grain of sand – contain a piezoelectric crystal that converts ultrasound vibrations from outside the body into electricity to power a tiny, on-board transistor that is in contact with a nerve or muscle fiber. A voltage spike in the fiber alters the circuit and the vibration of the crystal, which changes the echo detected by the ultrasound receiver, typically the same device that generates the vibrations. The slight change, called backscatter, allows them to determine the voltage.
Motes sprinkled thoughout the body
In their experiment, the UC Berkeley team powered up the passive sensors every 100 microseconds with six 540-nanosecond ultrasound pulses, which gave them a continual, real-time readout. They coated the first-generation motes – 3 millimeters long, 1 millimeter high and 4/5 millimeter thick – with surgical-grade epoxy, but they are currently building motes from biocompatible thin films which would potentially last in the body without degradation for a decade or more.
The sensor mote contains a piezoelectric crystal (silver cube) plus a simple electronic circuit that responds to the voltage across two electrodes to alter the backscatter from ultrasound pulses produced by a transducer outside the body. The voltage across the electrodes can be determined by analyzing the ultrasound backscatter.

While the experiments so far have involved the peripheral nervous system and muscles, the neural dust motes could work equally well in the central nervous system and brain to control prosthetics, the researchers say. Today’s implantable electrodes degrade within 1 to 2 years, and all connect to wires that pass through holes in the skull. Wireless sensors – dozens to a hundred – could be sealed in, avoiding infection and unwanted movement of the electrodes.
“The original goal of the neural dust project was to imagine the next generation of brain-machine interfaces, and to make it a viable clinical technology,” said neuroscience graduate student Ryan Neely. “If a paraplegic wants to control a computer or a robotic arm, you would just implant this electrode in the brain and it would last essentially a lifetime.”
In a paper published online in 2013, the researchers estimated that they could shrink the sensors down to a cube 50 microns on a side – about 2 thousandths of an inch, or half the width of a human hair. At that size, the motes could nestle up to just a few nerve axons and continually record their electrical activity.
“The beauty is that now, the sensors are small enough to have a good application in the peripheral nervous system, for bladder control or appetite suppression, for example,“ Carmena said. “The technology is not really there yet to get to the 50-micron target size, which we would need for the brain and central nervous system. Once it’s clinically proven, however, neural dust will just replace wire electrodes. This time, once you close up the brain, you’re done.“
The team is working now to miniaturize the device further, find more biocompatible materials and improve the surface transceiver that sends and receives the ultrasounds, ideally using beam-steering technology to focus the sounds waves on individual motes. They are now building little backpacks for rats to hold the ultrasound transceiver that will record data from implanted motes.

They’re also working to expand the motes’ ability to detect non-electrical signals, such as oxygen or hormone levels.
“The vision is to implant these neural dust motes anywhere in the body, and have a patch over the implanted site send ultrasonic waves to wake up and receive necessary information from the motes for the desired therapy you want,” said Dongjin Seo, a graduate student in electrical engineering and computer sciences. “Eventually you would use multiple implants and one patch that would ping each implant individually, or all simultaneously.”
Ultrasound vs radio
Maharbiz and Carmena conceived of the idea of neural dust about five years ago, but attempts to power an implantable device and read out the data using radio waves were disappointing. Radio attenuates very quickly with distance in tissue, so communicating with devices deep in the body would be difficult without using potentially damaging high-intensity radiation.
A sensor implanted on a peripheral nerve is powered and interrogated by an ultrasound transducer. The backscatter signal carries information about the voltage across the sensor’s two electrodes. The ‘dust’ mote was pinged every 100 microseconds with six 540-nanosecond ultrasound pulses.
Marharbiz hit on the idea of ultrasound, and in 2013 published a paper with Carmena, Seo and their colleagues describing how such a system might work. “Our first study demonstrated that the fundamental physics of ultrasound allowed for very, very small implants that could record and communicate neural data,” said Maharbiz. He and his students have now created that system.
“Ultrasound is much more efficient when you are targeting devices that are on the millimeter scale or smaller and that are embedded deep in the body,” Seo said. “You can get a lot of power into it and a lot more efficient transfer of energy and communication when using ultrasound as opposed to electromagnetic waves, which has been the go-to method for wirelessly transmitting power to miniature implants”
“Now that you have a reliable, minimally invasive neural pickup in your body, the technology could become the driver for a whole gamut of applications, things that today don’t even exist,“ Carmena said.
Other co-authors of the Neuron paper are graduate student Konlin Shen, undergraduate Utkarsh Singhal and UC Berkeley professors Elad Alon and Jan Rabaey. The work was supported by the Defense Advanced Research Projects Agency of the Department of Defense.

Former U.S. Representative From Ohio and Candidate for the President of the United States Dennis Kucinich's Attempted Ban of Space-Based Weapons
First off, see here for information on Electronic Warfare.
Dennis Kucinich attempted ban on space-based weapons, read more: http://thomas.loc.gov/cgi-bin/query/z?c107:H.R.2977:
This new class of weapons is being used on unaware, not informed humans, who of course did not consent to such experimentation. The Nuremberg Code of Conduct for experimentation with human subjects, is part of the Customary Law and the UDHR. The Code lists ten points, which universally have been adopted after the Nuremberg trials of war criminals by the Nuremberg Military Tribunals.
The secret technologies in question are covered by military/agency secrecy orders, mostly obtained under the US Inventions Secrecy Act, 1951. The US Patriot Act, for example, protects governments and connected criminals from criticism and/or detection and prosecution. Under this act anyone whistleblowing or fighting the system on a major concern is arbitrarily deemed to be unpatriotic. They can then be listed (by a senior politician or at the request, through them, of a connected criminal) as a security risk and harassed covertly; using secret technologies. In fact a Department Of Defense Directive, Directive 5240 1-R, 1994, gives open permission for those under surveillance to be used for remote experimentation. It's no coincidence that this particularly undemocratic and evil move was followed in 1996 by a significant increase in the number of satellites deployed for the purpose of civilian surveillance and harassment.
The victims are not openly confronted as that would remove any feigned excuses and leave the perpetrators open to all manner of accusation. Instead, the methods used are covert; employing high-tech methods to remotely torture, torment and deceive victims without leaving evidence.
The situation is getting worse not better with more and more secretive, undemocratic legislation being sneaked past the unwary public all the time. State treachery and terrorism are behind it yet it is all hidden under the guise of "the war on terror". For example, the US government just passed the National Defense Authorization Act of 2012, giving the President (and others) the power to target and silence anyone questioning State corruption. When this is done openly in other countries the US is the first to condemn such evil. Yet when they are guilty of the same they do it in secret and no-one dares to criticize them, lest they join the ranks of those they persecute.
Eg. In the USA over 300,000 NSL's (National Security Letters) have already been issued. These allow the agency targeting of innocent civilians whose objections to corruption / crime in high places have been deliberately skewed or misinterpreted as a threat to powerful people. Once placed in a program people can be abused and experimented on, from a distance (using satellites / high tech'). This effectively silences and discredits them while providing agency researchers with guinea pigs for experiments in control, brain function, dreams, health, robotics and much more. Post 9/11, $750 billion per year has been spent on satellite weapons used for human experimentation / targeting. Most of this has found it's way from government coffers to about 80 defense contractors who are also culpable for the crimes against humanity that are addressed on this site.
There is a circular / Catch 22 type problem in that governments use "classified" covers to hide criminal activity (esp. if it is an unconstitutional act) but targets can't prove any of that BECAUSE it has been classified. Executive Order 13526 section 1.7 (covering classified status allocation) specifically says that **"You cannot classify information merely to cover up a crime"**. Even if devices or procedures are classified this also applies to them and information on them when they are being used for criminal purposes. So, in theory, by misusing devices, abusing authority and so on, the administration not only commits crimes but should open up the information relating to that for public scrutiny...(Government of, by and for the people).
Now Presidents Obama and Bush both signed executive order 13526, so if any of these hidden crimes were to be presented to the US Supreme Court, any current US leader could be impeached as having breached their oath of office...which includes upholding the constitution.
The ECHELON spying system, remote neural monitoring, the use of directed energy weapons and more are all clearly crimes against the people and humanity in general and so by classifying the devices the government and it's leaders are breaching the constitution as well. As with any crime the break in the loop between the acts, investigation, trial and incarceration is the lack of proof. "Classifying" information and calling it a matter of National Security negates the need for the criminals involved to even create excuses for their conduct. The ability of government to classify crime is what must be fought.

Also, the US military is supposed to be prohibited by law from targeting US citizens with PSYOPS within US borders under Executive Order S-1233, DOD directive S-3321.1 and National Security Directive 130. Of course, there's no-one to police that especially since Psyops, by their very nature, are difficult to prove.
This is particularly so where the secret weapons discussed on this blog are employed. Also nothing stops agencies, US or allied, from doing that dirty work and hiding it under the National Security carpet. Nonetheless, public discussion of these Psyops crimes is beginning.
The International Commitee of the Red Cross (ICRC) raised the issue of psychotronic weapons; firstly in 1994, then the 2002 Geneva Forum and then the 2009 5th Symposium on non-lethal weapons. The EUROPEAN PARLIAMENT passed a "Resolution on the Environment, Security and Foreign Policy" - A4-0005/99, January 28th, 1999 which called for "An international convention introducing a global ban on ALL development and deployment of weapons which might enable any form of manipulation of human beings"..."It is our conviction that this ban can not be implemented without the global pressure of the informed general public on governments. Our major objective is to get across to the general public the real threat which these weapons represent for human rights and democracy and to apply pressure on the governments and the parliaments around the world to enact legislation which would prohibit the use of these devices to both government AND private organizations as well as individuals". (Plenary sessions / European Parliament, 1999). ]
