A biomimetic blade integrating water absorption, self-transport and infiltration

Abstract

The present invention is a bionic blade integrating water absorption, self-transport and penetration, comprising an adsorption self-transport layer, a base, a permeable layer and a petiole; the adsorption self-transport layer is arranged above the base, the petiole is arranged below the base, and the permeable layer is arranged At the center of the entire bionic leaf, it runs through the upper part of the adsorption self-transport layer, base and petiole, and communicates with the microchannels in the lower part of the petiole; the adsorption self-transport layer includes hydrophilic surfaces, super-hydrophobic tracks and micro-hydrophobic points. A through hole is opened at the center of the water surface, and the permeable layer is arranged in the through hole; a plurality of super-hydrophobic tracks and micro-hydrophobic points are arranged on the circumference of the through hole, and the super-hydrophobic track includes a third-level gradient channel, and the two sides of the third-level gradient channel There are multiple sets of second-level gradient channels, and multiple first-level gradient channels are arranged on the second-level gradient channels; the centerlines of the first-level gradient channels and the third-level gradient channels are parallel, and the present invention can absorb water in the air The fog is self-transported to a certain area and penetrates into the interior for storage.

Description

technical field [0001] The invention belongs to the field of on-line detection of soil ion concentration, and in particular relates to a bionic blade integrating water absorption, self-transportation and infiltration, which collects air moisture under passive conditions and forms an ion micro-solution supplement around the soil ion concentration on-line detection sensor. moisture. Background technique [0002] On-line detection of soil matrix ion concentration is one of the keys to realize intelligent cultivation automation. Due to loose soil particles, large gaps, large changes in components and moisture, etc., the water around the measuring electrode is insufficient, and it is difficult to form an ionic solution, resulting in poor measurement accuracy. In addition, the online detection of soil matrix ion concentration has higher requirements on the overall energy consumption and water source: it can realize water collection under the condition of low power consumption or ...
