In Artificial Intelligence, an agent is defined as an entity that perceives and acts in an environment. Here's an example of a cool technology for perceptual input.
"The tactile sensitivity of human skin is hard to re-create, especially over large, flexible surfaces. But two California research groups have made pressure-sensing devices that significantly advance the state of the art."
One, made by researchers at Stanford University, is based on organic electronics and is 1,000 times more sensitive than human skin. The second, made by researchers at the University of California, Berkeley, uses integrated arrays of nanowire transistors and requires very little power. Both devices are flexible and can be printed over large areas; they are described this week in separate papers in the journal Nature Materials.
