Abstract
An apparatus and method for monitoring a vehicle driver having at least one sensor for measuring pressure and/or humidity. The sensor includes at least one capacitor having at least two electrodes, which may be arranged horizontally on a flexible support material. At least one dielectric layer may be arranged between the electrodes. At least one electrode, and/or the dielectric layer, and at least one, at least partially liquid-permeable and/or liquid-absorbing moisture layer may be arranged on a side facing away from a support material. At least one electrode and/or the dielectric layer may be arranged transversely between the support material and the moisture layer. A capacitance may be changed by liquid on the dielectric layer, and a processing unit measures and/or stores values from the sensor, creating a capacitive humidity sensor. The processing unit may send the to a central CPU, wherein this data may be processed by the processing unit.
