The invention relates to a sensor, which is made of organic materials and can be used for the measurement of static and dynamic mechanical variables. Accelerations are measured by means of a strain gauge beam 1 having a seismic mass 2 at the end, wherein both are made of a flexible polymer. Due to the inertia of the seismic mass, the beam is deflected, resulting in expansion in the edge of the strain gauge beam 1, wherein the expansion can be measured by means of an intrinsically conductive polymer 3 that is structured into a strain gauge. The further modules 4, which comprise a measurement bridge, an amplifier circuit, a transmitter, and an optical display, or electrodes, are integrated on the substrate 5. A frame 6 may also be provided, which simplifies the handling of the overall system and may protect the strain gauge beam from lateral influences. The substrate 5 and the frame 6 are made of the same flexible polymer as the strain gauge beam 1 and the seismic mass 2. |
