A 3D-printable electrode that looks like a single strand of human hair has been developed that measures brain activity.
And it could make taking readings to diagnose things like epilepsy and sleep disorders much less complicated than they presently are.
Currently someone having an electroencephalogram , known as an EEG, requires their head to be covered in electrodes.
The standard EEG typically uses 21 of them, affixed to the scalp in strategic positions to capture activity from various brain regions.
But a team of researchers from the USA’s Pennsylvania State University reckons it has ushered in the future of EEG.
It has developed a single electrode that looks just like a strand of hair and is more reliable than the standard, multi-electrode version.
It’s designed to be worn continuously for long periods while not interfering with the wearer’s usual activities or drawing attention to its presence.
The electrode portion of the device is 3D-printed using a polymer hydrogel to be like a single strand of hair.
It can be printed using different biocompatible dyes to ensure the device matches the user’s hair colour.
On one end is the electrode which looks like a small dot and captures the brain’s electrical signals from the scalp.
The long, thin wire-like component extends from the electrode and connects to the monitoring system.
OPS: The lightweight and flexible electrode, which looks like a strand of hair, attaches directly to the scalp and delivers stable, high-quality recordings of the brain’s signals.

Londons Metropolitan Police train to use Taser stun guns.
The Metropolitan Police's Territorial Support Group. Sgt Alun Jones demonstrates a Taser.
The Taser is an electroshock weapon that uses electrical current to disrupt voluntary control of muscles. Its manufacturer, Taser International, calls the effects "neuromuscular incapacitation" and the devices' mechanism "Electro-Muscular Disruption (EMD) technology". Someone struck by a Taser experiences stimulation of his / her sensory nerves and motor nerves, resulting in strong involuntary muscle contractions.There are two main police models, the M26 and X26. Taser International is also marketing a civilian model called the C2. Tasers were introduced as less-lethal weapons to be used by police to subdue fleeing, belligerent, or potentially dangerous subjects. The use of Tasers has become controversial following instances of Taser use that have resulted in serious injury and death,and while they are far less lethal than many other weapons, the U.N. are concerned that use of Tasers may amount to torture, and Amnesty International has reported cases where they believe that their use amounted to "cruel, inhuman or degrading treatment which is absolutely prohibited under international law".
