AI Technical Summary
Technical Problem
Existing pressure sensors cannot simultaneously possess high sensing sensitivity, wide sensing range, and excellent reproducibility, and therefore cannot effectively monitor the comprehensive deformation of towers, from minute to large deformations.
Method used
A conductive material CRF was prepared by combining C-MOF powder with a polyaniline array, and then loaded onto a PU sponge skeleton and further adhered to a polylactic acid film to form a pressure sensor.
Benefits of technology
It achieves a wide operating range, high sensitivity, and fast response/recovery time for pressure sensors, enabling real-time monitoring of tower deformation and ensuring the safety of power transmission networks.
