The membrane structure is deflectable in a first stable deflection state and in a second stable deflection state and is operable in a resonance mode in at least one of the first and the second stable deflection states. The actuator is configured to deflect the membrane structure in a first actuation state into one of the first and the second stable deflection states, and to operate the membrane structure in a second actuation state in a resonance mode having an associated resonance frequency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensor element, particle sensor device and method for detecting a particulate matter density","description":"A sensor element includes a membrane structure suspended on a frame structure, wherein the membrane structure includes a membrane element and an actuator.
