Deciphering those circuits is critical to understanding how the brain works and what goes wrong in neurological disorders. MIT neuroscientists have now taken a major step toward that goal.

As designers continue to propose ever-smaller, ever-more-complex circuits, the demands on inspection equipment push the limits of what today's cameras can provide. Bruce Butkus, product line engineer ...

Figure 1 – A simple circuit showing power circuit causes bounce and must return to source The width of the GND and power lines should be guided by considering the acceptable loss. Typical 1-oz copper ...

Gene-based circuits are about to get decidedly more sophisticated. MIT scientists have developed a method for integrating both analog and digital computing into those circuits, turning living ...

Voigt and his students have now developed circuit components that don’t interfere with one another, allowing them to produce the most complex synthetic circuit ever built. The circuit, described in ...

The nanotube circuit is still relatively slow—its transistors are large and far apart compared to the latest silicon circuits. But the work is an important experimental demonstration of the potential ...

The Stanford group is currently working to make ever more complex integrated circuits. “So far as complexity is concerned, there is fundamentally no barrier” on carbon nanotubes, says Mitra.

Layered circuits To design synthetic circuits so they can be layered together, their inputs and outputs must mesh. With an electrical circuit, the inputs and outputs are always electricity.

That allows the circuits to buckle like an accordion when pulled or twisted without losing their electrical properties. Unfortunately, the materials used thus far are not compatible with human tissue.
