Abstract:
A capacitive sensor comprising:A. a first electrode assembly including:i. an elastic member disposed about and extending transverse to a central axis, and said elastic member having a first principal surface and a second principal surface on opposite sides thereof bounded by a peripheral portion of the elastic member,ii. one or more elongated petal elements, each of said petal elements connected to and extending in a direction at least in part perpendicular to said first principal surface from points on said first principal surface disposed about said central axis and said petals including an electrically conductive region at points distal from said first principal surface,B. a second electrode assembly including an electrically conductive element extending along an electrode axis,C. a support structure for fixedly supporting said peripheral portion of said elastic member with respect to said electrically conductive element of the second electrode assembly, whereby said central axis and said electrode axis are collinear and said conductive element is disposed opposite to and spaced apart from said conductive regions of said petal elements.
