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.

Abstract: Provided is an editable read-write data memory based on mechanical structure, including: a storage unit, a signal collection unit and a cantilever unit. The data memory is formed by arranging several storage units, and each of which includes a rotation unit and a variable-frequency unit. An N-pole magnet is provided on the rotation unit, and an S-pole probe is provided on the cantilever unit. When the external environment changes and drives the S-pole probe on the cantilever unit to approach the N-pole magnet on the rotating unit, the rotation unit rotates and drives the variable-frequency unit to buckle, and the change of buckling shape leads to a state change, so as to store data. The signal collection unit is connected with the variable-frequency unit, and the collected electrical signals are display. The stored information in the memory is read according to the change of the output electrical signals.
