Patent number: 7278327Abstract: Simultaneous pressure and position information is accurately measured in a sensor realized by utilizing first and second sensor elements that each exhibit a decreasing width over the length of the sensor element and that are arranged overlapping each other and in a substantially complementary orientation to one another with respect to the width so that the point of narrowest width of the first sensor element overlaps the point of the widest width of the second sensor element. Pressure applied to the sensor causes each sensor element to generate an electrical signal that is proportional to both the applied pressure and the surface area at the location of the applied pressure. As a result of the complementary orientation and overlapping for these sensor elements, the first and second sensor elements generate an asymmetric pair of signals that uniquely define the applied pressure by position and magnitude.Type: GrantFiled: July 26, 2005Date of Patent: October 9, 2007Assignee: New Jersey Institute of TechnologyInventors: Timothy N.
