Title:
SENSOR SYSTEM FOR CAPACITIVE DISTANCE MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2015/078466
Kind Code:
A1
Abstract:
The invention relates to a sensor system for capacitive distance measurement, comprising an evaluation unit, a first electrode unit, a second electrode unit spaced apart from the first electrode unit and a flexible, and elongated forming element connecting the first electrode unit and the second electrode unit to each other, the longitudinal direction of which elongated forming element defines a connection direction and which allows a position change of the two electrode units independently of each other, wherein the extension of the forming element transversely to the connection direction, which defines a transverse direction, is significantly smaller than the extension of the first electrode unit and/or of the second electrode unit in a direction parallel to the transverse direction. The invention further relates to an arrangement of such a sensor system.
