1. A MEMS device, comprising:

  • a cavity having an internal environment;

    a seal isolating the internal environment from an external environment outside the MEMS device,wherein the seal is susceptible to damage in response to a calibration unsealing energy, wherein upon damage to the seal, a pathway forms which couples the internal environment to the external environment, wherein the seal is a fusible link, and wherein the fusible link can damage the seal in response to an electrical current;

    a calibration circuit capable of measuring a parameter of the internal environment before and after damage to the seal; and

    a channel coupling a corner of the cavity to the seal.
