1. A temperature-dependent capacitor comprising:
a first conductive plate;
a second conductive plate located in a parallel-planar orientation to the first conductive plate; and
a dielectric separating the first conductive plate from the second conductive plate, wherein:
the dielectric is sufficiently flexible to allow movement of the first conductive plate relative to the second conductive plate in response to an increase in temperature of the first conductive plate, wherein the dielectric includes a combination of two or more distinct dielectric materials comprising:
a first dielectric material arranged adjacent to the second conductive plate, wherein there is—a positive correlation between temperature of the first dielectric-material—and dielectric constant (ε) value of the first dielectric material; and
a second dielectric material arranged adjacent to the first conductive plate; and
the first conductive plate is adapted such that a distance between at least a portion of the first conductive plate and at least a portion of the second conductive plate decreases as a temperature of the first conductive plate increases.
