Abstract
A capacitive detection device comprising: a capacitive detector comprising a ribbon made of a dielectric material, a pair of electrodes formed on a first face of said ribbon and comprising a first electrode and a second electrode in the form of combs whose branches are arranged alternately between one another; and a third electrode in the form of a layer formed on the other face of said ribbon; and further comprising a containment electrode arranged at least partly facing and at a distance from said pair of electrodes, this containment electrode being electrically connected to said third electrode. Measurement devices including this capacitive detection device are also disclosed.
