SENSOR SYSTEM WITH ACTUATED STRUCTURE RELEASING A COLOURED INDICATOR

摘要

The invention relates to a sensor system for detecting a target substance, and for providing visual indication of a presence of the target substance. The sensor system comprising at least a first fluid system, and a second fluid system containing a coloured or colour inducing indicator substance. The sensor system further comprises a flexible structure separating the at least first fluid system and the second fluid system, the flexible structure having a surface being functionalized to interact with a target substance in a fluid present in the first fluid system. The flexible structure upon exposure to the target substance releases energy stored in the flexible structure resulting in a mechanical actuation of the flexible structure, resulting in a release of the coloured substance either into the first fluid system or into a third fluid system connected to the second fluid system, or resulting in a colouring of a substance released either into the first fluid system or into a third fluid system connected to the second fluid system.
