Abstract: Disclosed is a waterproof sound-transmitting sheet for facilitating a visual inspection, which radiates a polymer material in a state of blending a pigment to form a waterproof layer having an achromatic color, thereby facilitating a vision inspection, and improving a water repellence even while making the waterproof sound-transmitting sheet thin and light. The disclosed waterproof sound-transmitting sheet for facilitating the visual inspection includes an acoustic layer interposed between an upper waterproof layer and a lower waterproof layer, and at least one of the upper waterproof layer and the lower waterproof layer is composed of a porous colored membrane having a color.

Abstract: Disclosed is a battery pressure detection apparatus, which operates in a short mode when a pressure of a standard level or more is applied to a battery, and recovers after the short mode operation to allow the repeated use. The disclosed battery pressure detection apparatus disposes a lower electrode under an upper electrode, interposes an elastic layer having conductive bodies distributed and disposed therein between the upper electrode and the lower electrode, and has a void disposed in at least one of an upper portion and a lower portion of the elastic layer.

Abstract: Disclosed is a method for producing a sensor and a battery pressure detecting sensor produced thereby, which operate in a short mode when a pressure of a standard level or more is applied, thereby preventing the breakage and ignition of a battery due to swelling. The disclosed battery pressure detecting sensor disposes a membrane sheet formed with a first accommodation hole under a conductive sheet, has a part of the conductive sheet connected to a first terminal through a first accommodation hole, and has the membrane sheet connected to a second terminal.
