Like when you push against the end of a con rod which then turns a crank which in turn turns a generator? In any way you need to push, stop pushing and then push again in order to have any usable energy.

You cannot gain energy from a constant pressure. Like the pressure at the bottom of the ocean or the pressure of you house pressing against the ground. You can only gain energy from a pressure gradient or a change in pressures. Take a balloon, blow it up, close it. The pressure in the balloon is now higher than outside the balloon. To gain energy from that difference you have to open the balloon and let the air out. Then you could hold a electric fan into the airstream and use it as a generator.

In Addition: You might be looking for piezo crystals.

They are used in electric lighters.
