Abstract
A device is provided that includes an electrically conductive structure on a non-conductive substrate for generating a time-dependent signal on a capacitive surface sensor. A method for generating a tamper-proof time-dependent signal on a surface sensor is also provided by means of such a device. A system or kit for carrying out the method and generating a time-dependent, tamper-proof signal on a capacitive surface sensor is also provided.

A method of generating a tamper-proof time-dependent signal on a surface sensor (20) comprising:
- a) providing an apparatus (22) having a capacitive surface sensor (20) and a device (10) comprising an electrically conductive structure (12) having structural elements (13) on a non-conductive substrate (14) for generating static signals (40) on the capacitive surface sensor (20);
- b) placing the device (10) on the surface sensor (20), thereby generating a set of static signals (40) on the surface sensor (20);
- and
- c) providing a dynamic input in the form of a movement and/or a gesture with an input means for generating an input signal (44) which is suitable for deflecting the static signals (40) on the capacitive surface sensor (20) and converting the static signals (40) into dynamic signals (42) so that the dynamic input signal (44) and the dynamic signals (42) represent a time-dependent overall signal (46) which can be evaluated by the apparatus (22) containing the surface sensor (20).
A system for generating a tamper-proof time-dependent signal (46) on a capacitive surface sensor (20), the system comprising a device (10) and an apparatus (22) comprising a capacitive surface sensor (20),
- characterized in that
- a) the device (10) comprises an electrically conductive structure (12) having structural elements (13) on a non-conductive substrate (14) adapted to generate a set of static signals (40) on the capacitive surface sensor (20),
- b) the static signals (40) can be deflected and converted into dynamic signals (42) by an additional input by means of an input means (30) on the capacitive surface sensor (20), and
- c) the dynamic input signal (44) generated by the input means (30) and the dynamic signals (42) represent a time-dependent overall signal (46) which is evaluated by the apparatus (22) comprising the surface sensor (20).
