During the drying process of MV, for the whole board, the effect of thermal diffusion on moisture movement is not significant, but it can cause a leveling of moisture profile in a local range of wood.

Combined with a water-based attractant derived from human sweat (collected from a wrist band), the trap mimics the scent, moisture, and temperature profile of a sleeping body.

By experiments, it analysed the influence of cross sections of profile fiber on the properties of moisture-transfer and dry-fast.
