Abstract

The paper presents the results of a project to create highly sensitive thermoelectric converters for small temperature differences on a flexible film base, consisting of a large number of compact thermocouples connected in series. Such sensors may be used, for example, as the part of fire alarm systems without any power supply. The sensors were produced as multilayer structure coating of thermoelectric alloys on the flexible polymer substrate through photolithographic masks. A pair of chromel-T and kopel was taken as thermoelectric alloys. The preliminary operating parameters of the obtained samples are presented.
