1. A downhole tool comprising:
an interior component having an outer diameter (OD) surface;
a protective housing positioned around at least a portion of the interior component and having an inner diameter (ID) surface proximate the OD surface of the interior component;
an adjustable damper including a piezoelectric layer positioned between the ID surface and the OD surface and configured to change size in a transverse direction perpendicular to a longitudinal axis of the interior component; and
wherein the piezoelectric layer and a damper layer are angularly adjacent to one another relative to a rotational axis of the downhole tool and the piezoelectric layer applies a tension force to the damper layer to change at least one dimension of the damper layer.
