  • Patent number: 12286354
    Abstract: A method for manufacturing a humidity alarm device based on laser-induced graphene is performed as follows. Carbon-based films are coated with a hydroxide ion-containing solution and processed by a laser device to generate hydrophilic graphene layers. The hydrophilic graphene layers are peeled off from the carbon-based films, wetted, and respectively wrapped around shaping rods varying in diameter. The wrapped rods are heated and shaped by a drying oven to obtain curled graphene switches. Each curled graphene switch is connected in series with an alarm lamp to form an alarm component. The alarm components are connected in parallel, and then connected to a positive terminal and a negative terminal of a power supply to form the humidity alarm device.
