Abstract
A sensor element may be provided for a monitoring device designed to protect displayed merchandise against theft. The sensor element may be flexible and include a sensor layer with a measuring circuit loop integrated therein. During attempted theft, a contact element that may be arranged on an adhesive surface creates an open in the measuring circuit loop, thereby triggering an alarm.
Claims10
A sensor element comprising:
- a sensor layer having a measuring circuit loop, the measuring circuit loop having a break, the sensor layer being fastenable to a device by way of an adhesive layer having a contact element positioned on a surface thereof, the contact element for short-circuiting the break of the measuring circuit loop, wherein the sensor element is one of flexible and elastic;
- wherein the sensor layer includes a second measuring circuit loop, the second measuring circuit loop having a break and being connected electrically in series to the measuring circuit loop, the sensor layer being attachable to a fastening element via a second adhesive layer, and the second adhesive layer includes another contact element for short-circuiting the break of the second measuring circuit loop.
A monitoring device for protecting displayed merchandise against theft, the monitoring device comprising:
- a processing circuit;
- a cable for connecting a sensor element with the processing circuit;
- wherein the sensor element includes a sensor layer having a measuring circuit loop, the measuring circuit loop including a break, the sensor layer being attachable to the merchandise by way of an adhesive layer, the adhesive layer having a contact element located on a surface thereof, the contact element for short-circuiting the break in the measuring circuit loop, and wherein the sensor element is one of flexible and elastic;
- and
- a second sensor element, the second sensor element at least for attaching the processing circuit to a member.
