Abstract: A sensor device for sensing wetness in an absorbent article worn by a subject includes one or more sensing elements; and a coupling for communicating sensor signals between the one or more sensing elements and a receiver. A change in environmental parameter causes a change in electrical behavior of at least one of the sensing elements, which behavior can be analyzed to determine occurrence of a wetness event in the absorbent article. The changes in electrical behavior are communicated in the sensor signals to the receiver. The analysis may be by the receiver or a processor in communication with the receiver. Ideally, the sensing elements include capacitive elements and preferably, resonance circuits.

Abstract: An apparatus for holding a tissue sample having a retaining member with a first tissue engaging surface and at least one biasing element. The first tissue engaging surface is moveably attached to the retaining member. The apparatus also has a base comprising a second tissue engaging surface which is configured to engage the retaining member to form an interior area with the first and second tissue engaging surfaces facing each other. The apparatus also has a retracting member connected to the retaining member which is configured to retract the first tissue engaging surface and compress the biasing element to form a gap between the tissue sample and one of the first tissue engaging surface and the second tissue engaging surface.
