An overcurrent protection device according to an embodiment of the present disclosure may include a first electrode disposed substantially parallel to a second electrode. A material may be disposed between the first electrode and the second electrode. A plurality of conductive material nodules may be 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. In response to an overcurrent condition the material may be 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.
