Title
(EN) THERMAL-SENSING FIBER DEVICES WITH SEMICONDUCTING ELEMENT
(FR) DISPOSITIFS A FIBRES THERMOSENSIBLES AVEC ELEMENT SEMI-CONDUCTEUR
Abstract
(EN)
There is provided a thermal sensing fiber (100) including a semiconducting element (102) having a fiber length and characterized by a bandgap energy corresponding to a selected operational temperature range for the fiber in which there can be produced a change in thermally-excited electronic charge carrier population in the semiconducting element in response to a temperature change in the selected temperature range. At least one pair of conducting electrodes (104,106,108,110) is provided in contact with the semiconducting element (102) along the fiber length, and an insulator is provided along the fiber length. An optical transmission element (172) can be comprised in said fiber (100) .Said fiber can be used for measuring ambient temperature as well as for self-heat-monitoring. A grid of such fibers is disclosed for monitoring surfaces or structures.

cette invention concerne une fibre thermosensible (100) d'une certaine longueur à élément semi-conducteur (102), caractérisée par une énergie de la largeur de bande correspondant à une plage donnée de température de fonctionnement pour la fibre dans laquelle une modification de la population porteuse de charges électroniques excitées thermiquement peut être produite dans l'élément semi-conducteur en repose à un changement de température survenu dans ladite plage de température. On trouve au moins une paire d'électrodes semi-conductrices (104,106,108,110) en contact avec l'élément semi-conducteur (102) le long de la fibre et un isolant le long de cette fibre. Un élément de transmission optique (172) peut être inclus dans ladite fibre (100). Cette fibre peut s'utiliser pour mesurer la température ambiante ainsi que pour l'auto-surveillance thermique. L'invention porte sur l'emploi de telles fibres pour la surveillance de surfaces ou de structures.
