19. A hermetically sealed electronic device comprising:
a housing having an interior gas space;
one or more electronic components disposed within the housing;
a composition that can generate a gaseous oxidizing agent component, wherein the gaseous oxidizing agent component can be generated to provide the gaseous oxidizing agent component in the interior gas space at a mole fraction in the range from 0.1 to less than 20 mole percent based on the total gas in the interior gas space, wherein the composition actively generates the gaseous oxidizing agent component;
a generating device configured to actively cause the composition to generate the gaseous oxidizing agent component;
one or more sensors disposed within the housing and configured to sense a physical parameter within the hermetically sealed electronic device, wherein the one or more sensors are chosen from at least one temperature sensor, at least one pressure sensor, at least one oxygen sensor, at least one thermal conductivity sensor, at least one electrochemical sensor, at least one optical sensor, at least one relative humidity sensor, and combinations thereof;
a control system configured to control the concentration of the gaseous oxidizing agent component within the interior gas space, wherein the control system is in electrical communication with the one or more sensors, and wherein the generating device is in electrical communication with at least one of the sensors in a manner to control the generating device.
