Neural Dust

Summary

Neural dust refers to millimeter-scale or smaller wireless sensors that can be implanted in or near nerves and the brain for chronic neural interfacing. Developed initially at UC Berkeley with DARPA funding, neural dust uses ultrasound rather than electromagnetic waves for power and communication, enabling tiny implantable devices that can record and stimulate neural activity.

Technical Specifications

Definition

• Millimeter to micron-scale wireless sensors
• Powered and communicated via ultrasound
• Battery-free operation
• Chronic implantation capability
• Scalable to thousands of sensors

Development

UC Berkeley Research Team

• Jose Carmena (UC Berkeley neuroscientist)
• Ed Boyden (MIT neuro-engineer)
• Michel Maharbiz (UC Berkeley)

Purpose

To study those electrical impulses, scientists need to record the activity of individual neurons, but they're limited by the micromachining techniques used to produce today's technology.

Technical Mechanism

Ultrasound Power Delivery

• Sound waves power the devices remotely
• No batteries required
• Enables extreme miniaturization
• Safe for chronic implantation

Backscatter Communication

• Devices reflect ultrasound waves
• Modulation encodes neural data
• Passive operation - no active transmission
• Multiple devices can operate simultaneously

Demonstrated Results

We show that ultrasound is effective at delivering power to mm-scale devices in tissue; likewise, passive, battery-less communication using backscatter enables high-fidelity transmission of electromyogram (EMG) and electroneurogram (ENG) signals from anesthetized rats.

Deployment Methods

Aerial Deployment

Sensors known as 'smart dust' are as small as a spec of dust. They are basically microelectromechanical particles that relay information to a base station. Deployed in a network of thousands or millions, they can provide much information.

Ingestion/Inhalation

Neural dust is being spread everywhere, through chemtrails, the food supply, medicines, vaccines - that assembles in your brain and even self replicates forming a biologic-electronic interface to turn you into a walking antenna.

In-Body Assembly

• Particles travel through blood
• Self-assemble at target locations
• Form mesh networks
• Create bio-electronic interface

Applications

Medical

• Neural recording and monitoring
• Muscle/nerve stimulation
• Brain-machine interfaces
• Peripheral nerve interfaces
• Real-time physiological tracking

Military (DARPA N3 Program)

• Non-surgical neural interfaces
• Minimally invasive approaches
• Neural dust as key component

Weaponized

• Mass-scale neural surveillance
• Remote manipulation of nervous systems
• Deployable, nearly undetectable sensors
• Body-wide monitoring network
• Integration with WBAN systems

Detection Challenges

• Too small for conventional medical imaging
• X-rays may not detect
• MRI limitations for non-metallic devices
• Requires specialized equipment

Body Sensor Networks

Integration with WBAN (Wireless Body Area Network):

Those Body Sensor Networks stick to you on the body like the smart dust.

Medical Body Area Network (MBAN):

Mandated by FCC in 2014. Allows remote wireless health monitoring of a patient over periods of time without any restriction to activities.

Future Implications

In the future, you will self-police and eventually we will have a sort of nano-tech, nano-surveillance that will be present everywhere via this smart dust. ~ Jacques Attali

Countermeasures

The only thing that could get rid of implants is an electromagnetic pulse (EMP). Because of the different types of nanotechnology, the smart dust, the graphene within people's bodies, it could only be killed with an EMP.

Detection methods:

• RFID scanning
• Specialized frequency analysis
• Blood analysis for nanomaterials
• Spectrum analysis
