Abstract

La présente invention concerne un dispositif (10) de mesure de forces d'interaction d'une unité cosmétique avec des fibres, comprenant : - une éprouvette de mesure (12), comprenant : des fibres (20) de forme allongée entre une première et une seconde extrémités ; et un support (22) relié à la première extrémité de chacune desdites fibres, - un capteur de force (14), et - un élément (16) d'assemblage dudit capteur avec le support de l'au moins une éprouvette, dans une configuration assemblée du dispositif, tel que dans ladite configuration assemblée, ledit capteur est apte à mesurer un effort dynamique exercé sur ledit support selon au moins une direction (38, Z).The present invention relates to a device (10) for measuring interaction forces of a cosmetic unit with fibers, comprising: - a measuring test tube (12), comprising: fibers (20) of elongated shape between a first and a second end; and a support (22) connected to the first end of each of said fibers, - a force sensor (14), and - an element (16) for assembling said sensor with the support of the at least one test piece, in a assembled configuration of the device, such as in said assembled configuration, said sensor is able to measure a dynamic force exerted on said support in at least one direction (38, Z).
