1. A locking isolator, comprising:
one or more joints, configured to transition from a clearance fit state to an interference fit state in response to a first change in temperature and to transition from the interference fit state to the clearance fit state in response to a second change in temperature;
a dampener, configured to attenuate transmission of vibration through the one or more joints when the one or more joints are in the clearance fit state;
a heating element, configured to cause at least one of the first change in temperature and the second change in temperature; and
a piezoelectric cantilever, configured to deflect in response to the vibration and to generate electrical energy to energize the heating element.
