The present disclosure relates to a three-dimensional micro-environment structure for controlling cell behavior, a three-dimensional surface and an array for controlling cell behavior, and a method for manufacturing the three-dimensional micro-environment structure.

Three-dimensional micro-environment structure for controlling cell behavior, three-dimensional surface for controlling cell behavior, and method for manufacturing array and three-dimensional micro-environment structure

A breathable waterproof sheet, which interposes a support layer having a plurality of holes formed therein, thus preventing a waterproof air-permeable layer from colliding with a pressure sensor by a water pressure. The breathable waterproof sheet includes a waterproof air-permeable layer formed of a film having elasticity, an adhesive layer having one surface adhered to one surface of the waterproof air-permeable layer, and a support layer having a plurality of air-permeable holes formed therein and having one surface adhered to the other surface of the adhesive layer.

Breathable waterproof sheet

A waterproof sound-transmitting sheet, which interposes an adhesive layer composed of a material having micropores formed therein, thus smoothing the flow of the air between a waterproof sound-transmitting layer and a support layer. The waterproof sound-transmitting sheet includes a waterproof sound-transmitting layer formed of a film having elasticity, an adhesive layer having one surface adhered to one surface of the waterproof sound-transmitting layer, and a support layer having one surface adhered to the other surface of the adhesive layer; and the adhesive layer includes a substrate having a pore formed therein and an adhesive agent formed on both surfaces of the substrate.

Waterproof sound-transmitting sheet

A waterproof sound-transmitting sheet, which forms a reinforcement member on a waterproof sound-transmitting layer, thus maintaining waterproof performance and sound-transmitting performance by minimizing the displacement amount while maintaining stretch-shrinkage performance at a water pressure of about 1 atm or more. The waterproof sound-transmitting sheet may be configured to include a waterproof sound-transmitting layer formed in a film shape having elasticity, a first adhesive layer adhered to one surface of the waterproof sound-transmitting layer, a second adhesive layer adhered to the other surface of the waterproof sound-transmitting layer, and a reinforcement member formed of a hardening material to be formed on the waterproof sound-transmitting layer, thus maintaining waterproof and sound-transmitting performance by minimizing the displacement amount while maintaining stretch-shrinkage performance of the waterproof sound-transmitting layer even when a pressure of about 1 atm or more is applied thereto.

Disclosed is a waterproof sound-transmitting sheet, which includes a waterproof layer of a nonporous material and a support layer of a porous material, and maintains waterproof performance and sound transmission performance at a water pressure of about 10 atm. The disclosed waterproof sound-transmitting sheet includes a waterproof layer formed of a film shape of a nonporous material, a first adhesive layer having one surface adhered to one surface of the waterproof layer, and a support layer formed of a film shape of a porous material, and having one surface adhered to the other surface of the adhesive layer; and the support layer can be composed of metal mesh or nonwoven fabric.

Disclosed herein is a waterproof sound-transmitting sheet having high sound transfer efficiency and excellent water proofing performance and a method of producing same. The waterproof sound-transmitting sheet includes: a film-shaped sound-transmitting layer made of a first polymer material; and a webbed pigment layer formed on at least one side of the sound-transmitting layer and made of a second polymer material containing a pigment having a predetermined color, wherein the second polymer material has a melting point higher than that of the first polymer material.

Waterproof sound transmitting sheet, and method for producing same

Disclosed herein is a waterproof sound-transmitting sheet, the thickness of which can easily be adjusted and which has a high sound transmitting efficiency and excellent waterproofness, and a method for producing same. The waterproof sound-transmitting sheet, which is attached to a sound hole of a case, includes: a support layer made of a film-shaped porous material and formed in the case; and a waterproofing layer formed on one side of the support layer in the shape of a porous nanoweb in which fine fiber strands are crosswisely layered and exposed to the outside of the case.

Disclosed herein is a waterproof sound-transmitting sheet having high sound transfer efficiency and excellent water proofing performance and a method for producing same. The waterproof sound-transmitting sheet includes: a sound-transmitting layer made of a polymer material and formed in the shape of a web having a plurality of pores; and a coating layer formed on at least one side of the sound-transmitting layer to block pores existing on the surface of the sound-transmitting layer.
