主权项

1. An active seal system, comprising:
a rotor having a rotating seal component and a first electrical generator element; and a stationary seal component disposed adjacent to the rotor and having a second electrical generator element and a piezoelectric portion in electrical communication with the second electrical generator element, wherein the first electrical generator element and the second electrical generator element are configured to cooperate to generate electrical power in the second electrical generator element when the rotor is rotated; and wherein the piezoelectric portion is configured to change a size of at least a part of the stationary seal component in response electrical power received from the second electrical generator element.
