Abstract
The position of a mechanical interaction in a sensor constructed from fabric is detected. A substantially constant electric current is established through elements of the fabric. A first electrical potential developed in a first plane is measured in response to such current. A second electrical potential developed in a second plane is also measured in response to the current. Then the measurements are processed to identify a position of the mechanical interaction. A calibration circuit is connected to provide an alternative route for current flow through the first plane and through the second plane.
