Title (EN) METHOD OF MANUFACTURING A PYROELECTRIC UNIT
(FR) PROCEDE DE FABRICATION D'UNE UNITE PYROELECTRIQUE
Abstract:
(EN) A method of manufacturing a pyroelectric unit which includes the steps of imparting a temperature change to pyroelectrically coupling particles dispersed between a pair of opposed electrodes (13, 14) applied by an electric field before the particles adhere to the electrode (13) when manufacturing a laminate of particles for a polycrystalline pyroelectric unit or composite pyroelectric unit, thereby forming a layer of pyroelectrically coupling particles on the electrode (13) so that the orientation of the pyroelectric axes is aligned in advance. This temperature change could be done by the steps of cooling the vicinity of the electrode (13) by evaporation from the surface of the dispersion liquid (12), thus lowering the temperature of the liquid as the particles approach the electrode (13). Thus, dipoles are induced on the particles, and the orientation of the polarity of the pyroelectric axes can be performed by the electric field between the electrode pair before the particles adhere to the electrode (13).
(FR) Un procédé de fabrication d'une unité pyroélectrique consiste à provoquer un changement de température dans des particules à accouplement pyroélectrique dispersées entre une paire d'électrodes opposées (13, 14) appliquées par un champ électrique avant que les particules n'adhèrent sur l'électrode (13) au cours de la fabrication d'un laminé de particules pour une unité pyroélectrique polycristalline ou une unité pyroélectrique composite, formant ainsi une couche de particules à accouplement pyroélectrique sur l'électrode (13) de telle sorte que l'orientation des axes pyroélectriques soit alignée à l'avance. Le changement de température peut être effectué par les étapes de refroidissement du voisinage de l'électrode (13) par évaporation à partir de la surface du liquide de dispersion (12), abaissant ainsi la température du liquide au fur et à mesure que les particules s'approchent de l'électrode (13). Ainsi, des bipôles sont induits dans les particules, et l'orientation de la polarité des axes pyroélectriques peut être effectuée par le champ électrique entre la paire d'électrodes avant que les particules n'adhèrent sur l'électrode (13).
