17. A device, comprising;
-
a flexible substrate supporting magnetic sensors and magnetization lines that carry currents inducing selective magnetization of the magnetic sensors; and one or more controllers to collect magnetic sensor signals from the magnetic sensors, wherein the one or more controllers collect reference magnetic sensor signals when the flexible substrate is flat, first polarity magnetic sensor signals in response to deformation of the flexible substrate in a first direction and second polarity magnetic sensor signals in response to deformation of the flexible substrate in a second direction. - View Dependent Claims (18, 19)
