摘要： A biosensor comprises a unit, comprising a substrate and an enzyme, which when brought into contact with the substrate is adapted to affect the substrate so that its conductivity changes as a function of time and temperature, and an electric circuit. The unit is included as a component in said electric circuit and the electric circuit is 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 invention also relates to the use of a biosensor, a label with such a biosensor and a method of indicating the status of a product with such a biosensor.

摘要： 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.
