Hygiene monitoring device with a sensing panel

A hygiene monitoring device comprising a sensing panel, the sensing panel comprising:

• an elongate flexible panel defining a longitudinal axis, the elongate flexible panel comprising a first pair of plates spaced apart from each other in a direction crossing the longitudinal axis and a second pair of plates spaced apart from each other in a direction crossing the longitudinal axis, the first pair of plates and the second pair of plates being disposed on a flexible substrate of the elongate flexible panel,
• wherein each plate of the first pair of plates and each plate of the second pair of plates is elongate along the longitudinal axis of the elongate flexible panel,
• wherein the first pair of plates is offset along the longitudinal axis with respect to the second pair of plates, and
• wherein the hygiene monitoring device is configured to measure an impedance between two of the plates.
