“In the field of human-computer interaction, researchers have developed a high-performance flexible stress sensor, which uses natural porous loofah as the matrix material and carbon nanoparticle/multi walled carbon nanotube multidimensional composite material as the conductive coating, with conductive anisotropy. The experimental results show that the sensor exhibits high sensitivity, low detection limit, fast response/recovery time, and maintains good consistency under cyclic loading in different stress ranges. In addition, the practical applications of sensors in encrypted communication and human joint motion detection have also been demonstrated, demonstrating their potential applications in multidimensional wearable electronic products and intelligent robots.”
