Injectable Electronics capable of melding with the Brain

A flexible electronic mesh was injected into the brains of mice to evaluate their neurological activity. Very impressively, these electronics are inserted using a needle that a diameter of 0.1 mm, but is capable of safely unfurling around 30 times that size in one place without causing any damage to the brain.

According to Charles Lieber from Harvard University, these traditional techniques involve surgeries which would make an opening to the size of the structure, however this defeats the advantages of the flexible electronics which is why syringe injection can be so powerful. According to Lieber, their foldable mesh electronic is capable of unfolding and integrating seamlessly with the biological tissue without causing any chronic damage and immune reactivity for the first time in history.

He further states that their procedure will make a huge impact on the research that is being conducted to help those that are suffering from locked-in syndrome communicate via brain implants. In the United States, a firm called BrainGate builds brain-machine interfaces which are capable of translating messages via a subject’s motor cortex to tis robotic prosthetics. So when a subject thinks about moving their prosthetic, it does move. This is an incredible achievement of science, however, according to Charles Lieber their electronics could do better.

According to him, their breakthrough can deliver fundamentally new ideas and bring results to these kind of studies. He further states that they are really making the new electronic network start to look and behave in a way that of the neural network is trying to interface to.
