Short summary
We present a concept for angle and position measurement based on metamaterials. The distance between the sensor and the rotating or moving metamaterial target is not limited to a precise value. We use state-of-the-art millimeter wave radar chip technology for read-out, initially intended for applications such as gesture recognition or contactless switches. We implement a demonstrator test setup and show the proof of principle.

The measurement principle shows how to measure calibration torque moment shunts in a 5 MN m torque standard machine using an interferometer and hinge flexure stiffness. The analysis of the measurement uncertainty influences shows that the measurement uncertainty of transversal force measurement ranges from 0.61 % to 3.04 % and stays constant at 1.7 % for torque measurement. A FE validation was performed. The measurement uncertainty of the calibration torque moment sank from 0.106 % to 0.100 %.

Short summary
NiCr-carbon thin-film strain gauges offer the outstanding characteristic of a very high strain sensitivity. This can be very advantageous for many high-precision mechanical sensors like load cells. A downside of sensors based on these NiCr-carbon strain gauges is a rather large creep error, meaning reversible signal deviations at a constant load. We present two applicable methods for adjustment of the creep error: a modification of the film composition and a modification of the strain transfer.

Short summary
In this paper, we present a tactile sensor based on the interaction of coils with a magnetic elastomer. The first experimental approach is sampling the sensor with indentations of constant depth at different positions. A mathematical model is used to reproduce the data. Afterwards, this model is applied to random indentations at the same depth. As a result, we provide conceptual proof for position determination in one direction as a basis for a refined sensor design and further model approaches.

Short summary
This paper introduces a new method to drastically reduce the anisotropic strain sensitivity of granular thin film strain gauges. As a result, these improved strain gauges produce a much higher sensor signal when used for force transducers with biaxial strain fields. This gauge type is also more advantageous for uniaxial stress measurements. The method is based on the creation of a certain topographic structure of the strain gauges; in our case, this was realized by a picosecond laser system.

Short summary
Multi-parameter sensing is examined for thickness shear mode resonators that are in mechanical contact with thin films and half-spaces on both sides. A formula is derived that delivers insight into a set of material and geometry parameters accessible by measurement. Further analysis addresses the problem of accuracy of extracted parameters at a given experimental uncertainty. The demonstrated procedure is suitable for developing experimental strategy for highly efficient multi-parameter sensing.

The basis of our work presented in this paper stems from the research on new materials, especially temperature-stable thin films that transform strain into a resistance change very effectively, allowing higher sensitivity and higher operating temperatures. Different sensor concepts for time-resolved cylinder pressure monitoring of combustion engines are realized and evaluated. Reliable sensors with a minimum of internal components are provided.

Short summary
An electrochemical hydrophone based on the principles of molecular electronic transfer (MET) is described. The paper presents theoretical and experimental results for the sensitivity and the level of self-noise determination for METH in the frequency range of 0.02–200 Hz, which determines the fields of acceptance of the devices being developed. An experimental model has been developed by using a force-balancing feedback. Different methods and techniques for its calibration have been developed.

We combine two modern trends in component fabrication, namely, the integration of sensors into machine parts and the 3-D-printing technology, which is rapidly emerging in the fabrication of standardized and customized components and prototypes. We present a 3-D-printed ‘smart’ screw with an integrated strain gauge. The signal of the sensor can be used to monitor the fastening process of the screw as well as the reduction in strength of the screw joint over time.

The presented work gives insight into the behaviour of co-resonantly coupled oscillating cantilever beams by means of electro-mechanical analogies. An electric circuit model is analysed with various stages of complexity, and conclusions are drawn regarding the applicability of the co-resonant concept for sensors. Furthermore, this is validated by a comparison between the theoretical predictions and experimental data.

The exploitation of new application fields and the drive to size reduction even in highly stable pressure sensing systems makes the extension of the operating temperature range of the microelectromechanical sensors (MEMS) essential. For this reason, a silicon-based pressure sensor with an application temperature ranging up to 300 °C and the associated manufacturing technology was developed. The evolved sensor has an excellent stability and is uncomplicated to mount due to its stress insensitivity.

We tested two types of home-made sensing elements – four coupled silicon micro-levers and a multilayer graphene membrane – which have the potential to further enhance the sensitivity of laser photoacoustic spectroscopy. Graphene sheets possess outstanding electromechanical properties and demonstrate impressive sensitivity as mass detectors. Their mechanical properties make them suitable for use as micro-/nano-levers or membranes, which could function as extremely sensitive pressure sensors.
