Soft and flexible electrodes monitor neural activity in humans

28-Apr-2021

Key points from article :

Researchers developed implantable electrodes that capture signals from a human or animal brain without causing tissue damage.

Monitor and eventually understand brain function in both healthy and diseased people.

"To record signals from the brain with good results, the electrode must be bio-friendly and flexible inside the brain tissue," - Jens Schouenborg, Lead researcher.

Researchers named their tailored electrodes “3D electrodes.”

They’re extremely soft and flexible, so they can make stable recordings of electrical activity in brain tissue.

Encapsulates the electrodes in a hard but dissolvable gelatin material, that’s very gentle on the brain’s delicate tissue.

"Our new tech lets us implant the most pliable electrodes... but still retain the exact shape inside the brain," - Johan Agorelius, Co-researcher.

The array of electrodes is a bundle of 8 thin gold leads.
