▎ 摘　　要

NOVELTY - The unit has a self-adhesive sensing unit provided with a porous structure. The self-adhesive sensing unit is made of carbon nanomaterial. Liquid is adsorbed in holes when the self-adhesive sensing unit is placed in the liquid. The self-adhesive sensing unit is adhered by van der Waals force between the carbon nanomaterial and a carrier. The movement of charges contained in the adsorbed liquid in the holes, which realizes the sensing function when the pressure of the liquid environment changes. The carbon nanomaterial is provided with carbon nanotubes, graphene or carbon black. The liquid environment is provided with an acidic, alkaline or marine liquid environment. USE - Self-adhesive sensing unit for liquid environment. ADVANTAGE - The unit adheres underwater by van der Waals force mounted on different carriers, absorbs liquid based on the pore structure of the self-adhesive sensing material, so that the charges in the liquid are fully adsorbed on the inner surface of the holes, moves the charge in the hole confinement space when the pressure fluctuation generated by the detected target is felt, generates real-time electrical signal corresponding to the pressure change to realize the sensing function, achieves long-term adhesion, is small in size, easy to carry, sensitive in monitoring, and can be monitored for a long time, and improves the adhesion strength. DESCRIPTION OF DRAWING(S) - The drawing shows a partial schematic view of the self-adhesive sensing unit for liquid environment.
