Abstract:
1. An apparatus for indicating whether a bed is wet, said apparatus comprising: a sheet with first and second electrodes, said the first and second electrodes each comprising electrically conductive material, and the first and second electrodes being located at a distance from each other in or at the sheet, a measuring circuit for measuring at least one of resistance, capacitance and impedance between the first and second electrodes, each of said first and second electrodes including respective first and second ends thereof, each of said first and second electrodes further including respective first and second electrical connection points at said respective first and second ends of said first and second electrodes, wherein said first and second electrical connection points for each of said first and second electrodes are configured for electrical connection to said measuring circuit, and a control unit for determining whether the bed is wet on the basis of the measurements from the measuring circuit.
