Abstract: The present invention concerns an elongated capacitive sensor (1) for fluid monitoring. The sensor (1) comprising: a fibre support (5) made of a dielectric material or dielectric composite material; and a first electrode (7, 9) and a second electrode (7, 9) arranged longitudinally along the fibre support (5), the first and second 5 electrodes forming together with the fibre support (5) a capacitive sensing element whose capacitance is dependent upon one or more electrical properties of one or more materials inside the support (5) and/or outside the support (5), and/or is dependent upon a change of materials configuration and associated overall change of one or more electrical properties inside the support (5) and/or outside the support (5).

Abstract: The method for drawing a fiber with a textured surface comprises the following steps: - forming of a preform from which the fiber is to be drawn with a textured surface; - addition of an outer layer to the textured preform to preserve the shape of the texture of the preform surface during the drawing operation; - drawing of a fiber from the preform, whereby the fiber keeps the formed texture of the preform surface and - removing the additional outer layer to leave the original surface textured fiber exposed. The obtained fiber can be used as a mold to form a textured hollow channel in another material, as a surface coating and as a pressure detector.

Abstract: One aspect of the present invention relates to a method of fabricating a chemically active fibre device (1) by thermal drawing. The method comprises the steps of providing a preform, the preform comprising a support element (3) at least partially made of a first polymeric material; and carrying out a thermal drawing process of the preform to produce a thermally drawn fibre. The preform comprises one or more chemically active agents and/or biological materials configured to react with a fluid sample when the one or more chemically active agents and/or biological materials are in contact with the fluid sample. In this manner miniaturised lab-in-fibre devices can be fabricated.
