A device (100) for intrusion detection comprises a housing (102), a controller (230), and one or more foils (220; 240; 260a, 260b). The housing defines an interior (280; 282). The controller is located in the interior. Each of the one or more foils includes a surface sensitive to a local action at the sensitive surface. The one or more sensitive surfaces at least partially enclose a volume defined by the interior. Each of the one or more foils is coupled to the controller and configured to output a signal that depends on a location of the action at the respective sensitive surface. |
