Structural temperature self-monitoring system based on chiral structured shape memory polymer

A structural temperature self-monitoring system based on a chiral structured shape memory polymer microporous plate, comprising a fixing apparatus (1), a chiral structured microporous plate (2) and a triboelectric nanogenerators set (3);

• wherein each chiral element of chiral structured microporous plate (2) is provided with one hexagonal cell (201) and six chiral legs (202), adjacent chiral elements are connected to each other through the chiral legs (202), and deformation of chiral structured microporous plate (2) occurs during a temperature change;
• and
• wherein the chiral structured microporous plate (2) is fixed at the fixing apparatus (1), and the triboelectric nanogenerators set (3) comprises two slidable triboelectric nanogenerators symmetrically distributed to collect deformation data of the chiral structured microporous plate (2) in converse directions, one electronic of the nanogenerators is fixed at a bracket (102) of fixing apparatus (1), the other electronic of the nanogenerators is fixed at and moves with the chiral structured microporous plate (2), and two electronics of the nanogenerators move relative to each other to emerge a voltage for measurement during the temperature change.
