Abstract
A Peltier effect device which detects in particular a condensation risk, includes a substrate and semiconducting bands disposed on the upper face of the substrate. The junctions connecting said bands which make up a series circuit are formed by semiconducting bands of N-type and P-type. Junctions of the same type, i.e., N-P type are situated on the central zone of the upper face of the substrate and defines a detection zone of the device. Semiconducting bands of one type are placed on one side of the upper face of the substrate and bands of the other type are placed on the other side of the upper face of the substrate. The substrate also includes at the peripheral zone of each band, except for a frontmost N-type band and a rearmost P-type band, a plated hole extending through the substrate to a lower face of the substrate and to a plating of the lower face such that a plated hole situated at an end of the P-type band is connected to a plated hole situated at an end of a next N-type band.
