Investigation of low-temperature cofired ceramics packages for high-temperature SAW sensors [PDF]
Journal of Sensors and Sensor Systems, 2016 Surface acoustic wave (SAW) temperature sensor devices have been developed for operating temperatures up to and above 1000 °C. A challenging task to make these devices available on the market is to develop an appropriate housing concept.

Automated contactless characterization of local thin film thickness and film stress with standard MEMS structures at wafer level [PDF]
Journal of Sensors and Sensor SystemsThe fabrication of microelectromechanical systems (MEMS) devices comprises many steps, each of which adds to the tolerance, resulting in device performances that may fall outside the defined limits in the design process.

Large strain actuation in polypyrrole actuators [PDF]
SPIE Proceedings, 2004 A typical limitation of polypyrrole based conducting polymer actuators is the low achievable active linear strains (2 % recoverable at 10 MPa, 7 % max) that these active materials exhibit when activated in a common propylene carbonate / tetraethylammonium hexafluorophosphate electrolyte.

Biosensing System for Concentration Quantification of Magnetically Labeled E. coli in Water Samples
Sensors, 2018 Bacterial contamination of water sources (e.g., lakes, rivers and springs) from waterborne bacteria is a crucial water safety issue and its prevention is of the utmost significance since it threatens the health and well-being of wildlife, livestock, and ...

Correction to: TDOA versus ATDOA for wide area multilateration system
EURASIP Journal on Wireless Communications and Networking, 2020 The paper (Stefanski and Sadowski, EURASIP J. Wirel. Commun. Netw. 2018, Article 179) introduces a multilateration algorithm for unsynchronized sensor networks. However, a very similar method has been proposed before that is not cited.

, 2017 IntroductionThe term actuation problem was first introduced and defined by Weinreich, Labov and Herzog (1968:102). In their words: (1) The actuation problemWhat factors can account for the actuation of changes? Why do changes in a structural feature take place in a particular language at a particular time, but not in other languages with the same ...
