A switch device capable of safely opening or short-circuiting an electrical circuit in response to an abnormality such as wetting with water or liquid leaking from a battery is provided. The device includes first and second conductors connected to an external circuit, and a reaction part including an insulating material which changes state on contact with a liquid, the first and second conductors being electrically connected or disconnected by the insulating material changing state on contact with the liquid.

An elongated sensor for detecting the presence of a particular fluid includes first and second conductors, both extending from the proximal end to the distal end of the sensor. The second conductor includes a swellable conductor, at least a portion of the swellable conductor is swollen when in contact with the fluid and its conductance at least 10 times less when the portion is in contact with the fluid than when absent contact with the fluid. The second conductor further includes a subsidiary conductor in direct contact with the swellable conductor. In one embodiment the first conductor is isolated from the second conductor in the inner part of the sensor, and the two conductors are electrically connected at the distal end of the sensor. In another embodiment, the first contactor is in direct contact with the subsidiary conductor within the inner part of the sensor.

An incontinence detection system monitors an area for moisture events and wirelessly transmits moisture-related information to one or more notification devices. The system has a pad that includes a substrate and one or more sensors supported by the substrate. The sensor(s) emit wireless signals indicative of the moisture-related information. A sensor event communication system forwards the sensor signals to another device, such as a notification device. Portions of the system are included in a patient support apparatus, such as a bed.

The present disclosure relates to a water detection device that includes a water-activated battery configured to switch from a dormant condition to an active condition upon contact with water, such that the water-activated battery supplies an electrical voltage upon contact with the water, an electronic circuit configured to receive the electrical voltage from the water-activated battery, where the electronic circuit is configured to communicate with an external, electronic device via one or more wireless communication techniques when the electronic circuit is powered by the electrical voltage, and where communication between the electronic circuit and the external, electronic device is an uninterrupted communication when the electronic circuit is receiving the electrical voltage from the water-activated battery, and a housing configured to receive the water-activated battery and the electronic circuit, where the housing has passageways configured to facilitate movement of the water into the housing and toward the battery.

An example a method of manufacturing a film is provided. The method involves dissolving a backbone material in a non-aqueous solvent to form a non-aqueous solution. The method further involves adding the non-aqueous solution to an aqueous solution to form a liquid-liquid interface and injecting a particulate proximate to the liquid-liquid interface the non-aqueous solution is then evaporated to form a film containing the particulate. The film may be used in devices such as sensor devices for detecting hydrocarbons.
