AI Technical Summary
Current implantable microelectrodes face challenges in handling and accurate fabrication due to their small dimensions and three-dimensional structures, making them difficult to implant and interface with biological tissues reliably.
A substrate for implantable microelectrodes is designed with a flexible non-swelling base layer and a swelling layer that can deform and curve around biological tissues upon contact with water, allowing for self-folding and stable interfacing through a controlled mechanism.
The substrate enables reliable and controlled self-folding around biological tissues, facilitating accurate implantation and improved signal recording and stimulation efficiency by providing a stable interface with minimal manual intervention.
