Neural Dust (DARPA ElectRx)
artifactBiotech & Transhumanism · Defense & Military-Industrial
Scientists built specks small enough to sit inside your nerves and report back wirelessly, powered by sound.
Who they are
Neural Dust, millimeter-scale implants developed under DARPA's ElectRx program[1].
What they do
The engine treats it as technology letting the body's peripheral nervous system be continuously watched and even controlled.
How it works
These tiny batteryless sensors (0.8mm x 3mm x 1mm) are placed inside nerve or muscle tissue and are powered and read using ultrasound bouncing off them — no batteries, no wires (published in Neuron, August 2016, by UC Berkeley). A later advance, EGNITE graphene electrodes (Nature Nanotechnology 2024), added two-way high-resolution neural recording.
Why it matters
It means the nerves running through your body could be monitored and modulated around the clock, a building block for deep human-machine integration.
The engine's record — word for word
Millimeter-scale batteryless piezoelectric implants (0.8mm x 3mm x 1mm) deployed in vivo into nerve/muscle fibers. Powered and read via ultrasound backscatter — no batteries, no wires. Published Neuron Aug 2016, UC Berkeley. Enables continuous deep-tissue electrophysiological telemetry and modulation. Subsequent EGNITE graphene electrodes (Nature Nanotechnology 2024) achieve bidirectional high-resolution neural recording. Ensures peripheral nervous system can be continuously monitored and controlled.
