Abstract
A self-energy type thermal response monitoring device includes a periphery constraint assembly, a variable-frequency beam arranged in the periphery constraint assembly, piezoelectric patches covering the variable-frequency beam, and an electric signal collector electrically connected to the piezoelectric patches. Deformation of the variable-frequency beam is limited by innovatively using rigid constraint, and a low-frequency thermal load is converted into a high-frequency post-buckling impact to trigger a piezoelectric material to generate an electric signal.
