We present an approach to measure in situ the local temperature increase in the exposed volume during three-dimensional direct laser writing. The method is based on the detection of the luminescence of NaYF4:Yb3+/Er3+ codoped nanocrystals.
A fully ink jet printed humidity sensor on a thin PET foil is presented in this paper. Conductive silver electrodes were ink jet printed in the first step. Afterwards film forming polymer particles were printed on top as the humidity sensitive layer. Capacitance measurements were performed to investigate the sensor behavior at different humidity levels. By optimization of the electrode printing parameters...
Passive RFID transponder applications, requiring integrated sensors, can greatly benefit from unconventional sensing strategies. Especially in situations where there is the need to continuously monitor environmental properties, but without having access to an energy source or an omnipresent reader station in communication range. Since in many cases the violation of a threshold value is of interest,...
So far, embedded sensor networks in composites have mostly been used for structure health monitoring. In contrast to that, in the present work a new stand-alone embedded sensor network for load monitoring of a composite component is presented. Design considerations for the manufacturing of a demonstrator as well as measurement results for cyclic loading are discussed. The presented demonstrator comprises...
