Future of Engineering

Performing digital signal processing using organic and chemical materials without electrical currents could be the wave of the future — or so argue sotirios tsaftaris, research professor of electrical engineering and computer science, and aggelos katsaggelos, ameritech professor of electrical engineering and computer science, in their recently published "point of view" piece in the march 2008 edition of proceedings of the ieee.

Digital signal processing uses mathematics and other techniques to manipulate signals like images (natural medical, and others) and sound waves after those signals have been converted to a digital form. This processing can enhance images and compress data for storage and transmission, and such processing chips are found in cell phones, ipods, and hd tvs.

But over the past 10 years, scientists and engineers around the world have experimented with performing signal processing using different materials. In their piece, tsaftaris and katsaggelos describe these experiments while stirring the engineering community towards "a possible not-so-electronic future" of digital signal processing.
