AI Technical Summary

Technical Problem

Existing sensor devices in multilayer composite articles face challenges in transmitting measurement data externally due to vulnerability to external influences and difficulties in signal assignment in complex systems, and current data transmission methods are susceptible to unauthorized access.

Method used

An interface element with a contacting element and sealing element protects the electrically conductive structure within a multilayer composite body, allowing secure and protected data transmission via mechanical electrical contact, using a compressible and elastically deformable sealing element that conforms to the composite body's surface, and a positive-locking mechanism for a stable connection.

Benefits of technology

Ensures reliable and protected data transmission from the sensor device, safeguarding against external influences and ensuring a stable electrical connection under dynamic conditions.
