For a very long time, scientists have dreamed about combining electronics with the human body, and now it would appear that they have succeeded. A group of experts managed to create a type of circuit that essentially dissolved into the human body. The way they accomplished that was by combining thin, flexible silicon electronics with silk substrates. The innovative work went as far as creating arrays of transistors that were based entirely on thin films of silk, Technology Review reports.
 
The main role of the fabric is to ensure that the circuits are in tune with the body. Other circuits, for example, need to be protected when inserted into a living organism, but the new, silicon-based ones do not. Over a period of time, the silk melts away inside the body and only the silicon wires remain. However, they do not cause irritations, because they are only nanometers thick, and, therefore, nearly inexistent. “Current medical devices are very limited by the fact that the active electronics have to be 'canned,' or isolated from the body, and are on rigid silicon,” University of Pennsylvania Associate Professor of Neurology and Bioengineering Brian Litt says.
