How Silk-Based Electronics Are Transforming Neurology
Imagine a future where severe neurological conditions like epilepsy could be managed not with invasive brain surgeries or powerful medications with debilitating side effects, but with a tiny, dissolvable electronic interface thinner than a human hair.
Revolutionary approach using nature's materials for brain interfaces
Unprecedented stability in recording brain activity
Transforming how we diagnose and treat brain disorders
Creates mismatch with brain's soft tissue, leading to inflammation and scar tissue formation 8
Causes degradation, swelling, and conductive failure in conventional materials 6
Skull bone attenuates 80-90% of electrical signals, especially low-frequency brain waves 8
The breakthrough centers on transforming silk fibroin through oriented crystallization (OC), creating a material with:
This transformed material overcomes the limitations of conventional silk that rapidly absorbs water in biological environments 6
