Abstract: An infrared sensor with a microstructure has a multiplicity of sensor rods protruding from a sensor base and arranged axially parallel to one another. Each of the sensor rods is designed as a thermocouple, in that a first rod end, arranged on the sensor base, is electrically connected to an opposite free second rod end by both a first and a second electrically conductive rod element. The two rod elements have a different Seebeck coefficient, and the first rod element is formed as a hollow profile and the second rod element is arranged in the first rod element such that each thermocouple is formed as a single rod with a small standing area on the sensor base.

The device for energy conversion has a piezoelectric, mechanically vibrating diaphragm structure for converting mechanical energy into electrical energy and/or vice versa, the diaphragm structure being arranged encapsulated in an environment which has a predetermined pressure which is, in particular, lower than an isostatic pressure.

Abstract: A first dynamically deflectable membrane structure has two electrode layers and one piezoelectric layer for converting mechanical capacity into electrical capacity, and vice versa. The first membrane structure is mechanically coupled to extra weight. Mechanical and electrical capacities are provided which reduce a non-linear portion of a resetting force of the membrane structure. A second membrane structure is mechanically counter-coupled to the first membrane structure such that both membrane structures are mechanically biased in opposite directions by the extra weight. In this manner, a linearization of the resetting forces occurs as a function of the membrane deflection. The piezoelectric energy converter can generate an electrical capacity of, for example, 0.4 watts to 10 watts.
