IBM moves toward post-silicon transistor

Joab Jackson | March 22, 2013
Exploring methods of computing without silicon, IBM has found a way to make transistors that could be fashioned into virtual circuitry that mimics how the human brain operates.

To work, such circuitry would take advantage of microfluidics, the emerging practice of engineering around how to tightly control small amounts of liquids in a system. "We would direct fluids to particular surfaces or three-dimensional structures of oxides and then change their properties by applying gate voltages," Parkin said. Entire virtual circuits could be built and once their work is finished, they could be torn down by simply passing liquid though other channels.
