FLEXIBLE THERMOACOUSTIC DEVICE, AND FLAG INCLUDING THE SAME AND USING THERMOACOUSTIC ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a flexible thermoacoustic device using carbon nanotubes, and a flag including the same and using a thermoacoustic element.

SOLUTION: This flexible thermoacoustic device includes a flexible supporter and a sound wave generator. The sound wave generator is installed on a surface of the flexible supporter. The sound wave generator includes a carbon nanotube structure. In the carbon nanotube structure, a plurality of carbon nanotubes are combined by intermolecular force. The thermal capacity per unit area of the carbon nanotube structure is ≤2×10-4J/(cm2K).
