Thermal sensor

摘要

A thermal sensor includes a first electrode, a second electrode, and a plurality of beads disposed between the first electrode and the second electrode, the beads defining bead cavities between each other. A method for manufacturing a thermal sensor includes disposing a plurality of beads on an inner electrode, dip coating the inner electrode with beads using a molten state changing material, and disposing an outer electrode over the inner electrode and beads after dip coating.

1. A thermal sensor, comprising:
a first electrode; a second electrode; and a plurality of beads disposed between the first electrode and the second electrode, the beads defining bead cavities between each other; and a state changing material disposed in the bead cavities, wherein the state changing material transitions between a non-conductive state to a conductive state at a threshold temperature, wherein, in the conductive state, the state change material electrically connects the first and second electrodes.
