Japanese researchers have demonstrated a new type of resin that could be used in 3D micro-electrodes that interface with the brain. With the material, it's possible to micro-sculpt tiny objects that hold their shape after being "carbonized" at 800 degrees Celsius, which increases electrical conductivity; the process reduces models made with other available resins to a charred, shapeless blob.
The image above shows how the resin was used to reproduce the "Stanford bunny," a common test blueprint for 3D modeling and printing. Though the model on the right, seen after undergoing the carbonizing process, shrank by around 20 percent, it held its shape and integrity well. This allows for the creation of complex structures just a few...
