Abstract
A temperature exposure indicator includes a first temperature responsive material, a capacitor including a first electrode, a second electrode, and a gap between the first electrode and the second electrode, and a first path connecting the first temperature responsive material to the gap. The first temperature responsive material is configured to migrate along the first path and into or along the gap in response to exposure to a temperature above a first threshold temperature. The migration of the first temperature responsive material into or along the gap causes a change of the capacitance of the capacitor.
