Abstract: An electroconductive thermal insulating material includes first domains and at least one second domain. The first domains each have a phononic crystal, and the phononic crystal has holes arranged in plan view. The second domain is a domain formed around the first domain in plan view and having no hole.

Abstract: A thermoelectric conversion element includes a p-type thermoelectric converter, an n-type thermoelectric converter, a first electrode, a second electrode, and a third electrode. One end of the p-type converter is electrically connected to one end of the n-type converter. The other end of the p-type converter is electrically connected to the second electrode, and the other end of the n-type converter is electrically connected to the third electrode. The p-type converter includes a first phononic crystal layer having a first phononic crystal structure including regularly arranged first through holes. The n-type converter includes a second phononic crystal layer having a second phononic crystal structure including regularly arranged second through holes. The through direction of the first through holes is a direction extending between the ends of the p-type converter. The through direction of the second through holes is a direction extending between the ends of the n-type converter.

Abstract: A temperature sensor is a temperature sensor using a MEMS resonator, and includes: a MEMS resonator; a sweeper that sweeps a frequency of an excitation signal for a vibrator of the MEMS resonator in a predetermined sweep direction, and outputs the excitation signal swept to the MEMS resonator; a discontinuity point detector that obtains a vibration state information signal, which is a characteristic quantity expressing a vibration state of the vibrator based on the excitation signal, from the MEMS resonator, and detects a detection value that is (i) a frequency of the excitation signal when the vibration state information signal obtained changes discontinuously or (ii) a time corresponding to the frequency; and a converter that determines a physical quantity acting on the MEMS resonator based on the detection value detected.
