Overcurrent protection device and method of forming an overcurrent protection device

An overcurrent protection device, comprising:

• a first electrode disposed substantially parallel to a second electrode;
• a material disposed between the first electrode and the second electrode;
• and
• a plurality of conductive material nodules disposed in the material between the first electrode and the second electrode, including a first conductive material nodule at least partially contacting an inner surface of the first electrode and a second conductive material nodule at least partially contacting an inner surface of the second electrode and the first conductive material nodule, wherein a thickness of the material between the first electrode and the second electrode is less than or equal to a sum of a length of the first conductive material nodule and a length of the second conductive material nodule;
• wherein in response to an overcurrent condition the material is configured to expand, such that the contact between the first electrode, the first conductive material nodule, the second conductive material nodule, and the second electrode is at least partially interrupted.
