A sensor system. The sensory system includes a substrate extending in a substrate plane, a closed cavity and a movable structure in the closed cavity, at least one portion of the movable structure being situated at a distance opposite a surface of the substrate extending in parallel to the main extension plane within the cavity, the distance varying when the movable structure is deflected, a temperature difference between the surface of the substrate and the movable structure being measurable by an action of force on the movable structure.

A method for temperature compensation of a MEMS sensor. The method includes: in a balancing step, a temperature gradient is produced by a thermal element and a first and a second temperature are determined at a first and a second temperature measurement point, wherein a deflection of a movable structure produced by the temperature gradient is measured and a compensation value is ascertained dependent on the first and second temperature and the deflection; in a measurement step, a physical stimulus is measured by way of a deflection of the movable structure and a third and fourth temperature is determined at the first and second temperature measurement points; in a compensation step, a measured value of the physical stimulus is ascertained dependent on the measured deflection, the third and fourth temperature and the compensation value. A method is also provided including: a regulation step, and a measurement step.

A method for calibrating a structure-borne sound-sensitive acceleration sensor with the aid of at least one microphone. For this purpose, the acceleration sensor is situated in an intended position on the body of a user. Furthermore, at least one acceleration sensor signal and at least one microphone signal are detected, the at least one acceleration sensor signal and the at least one microphone signal being synchronized and having been caused by a vocalization of the user.
