Patent number: 9132044Abstract: A system is provided for detecting moisture at an absorbent article. The system includes a device arranged to be attached on the absorbent article and a resonance circuit including a moisture sensitive part, wherein the resonance circuit has a first resonance frequency when the moisture sensitive part is in a dry condition and a second resonance frequency when the moisture sensitive part is in a moist condition. The system further includes a monitoring unit being arranged to transmit a test signal to the device, receive a response signal from the device, determine a frequency of the response signal and generate a detection signal if the determined frequency corresponds to the second resonance frequency. There is also provided a method for detecting moisture at a device attached on an absorbent article.Type: GrantFiled: October 5, 2010Date of Patent: September 15, 2015Assignee: Pampett ABInventors: Johan Sjöholm, Christofer Lundin, Olle Hydbom

Patent number: 7071830Abstract: A sensor for indicating moisture, comprising a unit whose conductivity is dependent on the current moisture exposure and an electric circuit, the unit being included as a component in the electric circuit and the electric circuit being activable by applying an electric field and/or a magnetic field over the same to generate a measurable signal, which is dependent on the total resistance of the circuit. The unit comprises an enzyme together with a substrate, which enzyme is activated when moisture exposure occurs to catalyse a reaction with the substrate that is dependent on the degree of moisture exposure, the substrate reaction product increasing the conductivity of the unit. The invention also relates to the use of such a sensor and a method of using a sensor to indicate moisture.Type: GrantFiled: July 3, 2002Date of Patent: July 4, 2006Assignee: Bioett ABInventors: Bengt Sahlberg, Johan Sjöholm, Ernst Wehtje, Per-Olof Erlandsson
