Maybe! A patent application, filed in 2010 but only recently uncovered, has Sony looking at biometric controls on devices that look like a DualShock, a PlayStation Move controller, and a handheld.
What does that actually mean? It means the controllers would be able to measure your skin moisture, heart rhythm and muscle movement and use those to help control or influence a game.
This is quite a few steps beyond Nintendo's ill-fated Vitality Sensor, which basically would only read your pulse (and which has since been put on the shelf because it didn't work very well).
Some of the possible applications for using this data include a game's difficulty adapting to match your stress levels and a game's soundtrack adapting to...match your stress levels.
Remember, though, unlike the Vitality Sensor, which was officially announced by Nintendo, these are just patent applications, meaning it's just stuff Sony is thinking about, not necessarily intending to bring to market.
