Abstract
A sensor element includes an acoustic emission sensor for detecting acoustic emission. The sensor element has a second sensor for a second measured variable which is different from acoustic emission. Furthermore, a sensor element is provided, which includes an acoustic emission sensor for detecting acoustic emission and includes an interface for receiving an external sensor signal.

1-10. (canceled)
A sensor element, comprising:
- an acoustic emission sensor configured to measure acoustic emission;
- and
- one or more second sensors, each of the one or more second sensors being configured to measure a quantity that is different from acoustic emission.
A sensor element, comprising:
- an acoustic emission sensor configured to generate first electrical signals based on a strength and/or direction of measured acoustic emission from a monitoring object;
- and
- one or more second sensors, each of the one or more second sensors being configured to generate second electrical signals based on a measured physical characteristic from the monitoring object that is different from the measured acoustic emission.
A sensing method, comprising:
- measuring acoustic emission from a monitoring object;
- and
- measuring one or more physical quantities from the monitoring object that are different from the measured acoustic emission.
