Flexible resin is selected as the elastic material
and the body-centered cubic (BCC)lattice structure prepared by digital light processing (DLP) printing technology is used as the substrate.Multi-walled carbon nanotubes (MWCNTs) are bonded to the lattice framework through ultrasonic impregnation coating.A 3D flexible piezoresistive pressure sensor based on MWCNTs is prepared.The research results show that the sensor achieves a high sensitivity of 0.798kPa
-1
in the range of 0~13.2kPa.More notably
the sensor also demonstrates fast response times of 160 and 200ms under 60% deformation compression-release and good cycling characteristics under 600 compressio
n cycle tests.The sensor also shows good response feedback in the designed gait detection experiment
showing its potential for wide application in the field of health detection.
