February 2018: Magnetic measurements for medical diagnostics

In the future, highly-sensitive sensors could be able to detect magnetic signals from the body in order to draw conclusions on heart or brain functions. In contrast with established electrical measurement techniques, they would achieve contactless measurement, i.e. without direct skin contact. At present, such measurements are still associated with considerable expense and effort. This is because the sensors must…

February 2018: New Phase Noise Measurement Device

Our new phase noise analyzer FSWP from Rohde & Schwarz has just arrived. With this measurement device the phase noise (and also the amplitude noise) of both one-port and two-port devices under test (DUT) can be measured. One-port measurements are particularly necessary for the noise characterization of the oscillators used for the excitation of our sensors. However, the main feature…

December 2017: Magnetic Measurement of Nerve Signals

A highlight, especially for the team of the projects B2 and B6 of the CRC 1261, was the magnetic measurement of nerve signals with a 304 SQUID vector magnetometer at the PTB in Berlin. For further development and also for optimization of our uncooled magnetoelectric (ME) sensors, a better understanding of spectral power distribution and signal strength of nerve signals…

July 2017: Localization of Magnetic Nanoparticles

Ron-Marco Friedrich recently reported on great progress the project project B7. Here, the aim is the detection of magnetically labeled cells for biomaterial scaffold characterization and first measurements of the magnetic field and localization of magnetic nanoparticles were successful. For the measurement, an ME sensor samples space over a surface with magnetic nanoparticles (Fig. 1). The magnetic field is measured…

July 2017: New Sensor Characterization form Central Project Z2

Good news from our central project Z2. Alexander Teplyuk (project Z2) has finished a new scheme for mounting and characterization of our cantilever-based ME sensors. Instead of of permanenty fixing the cantilevers on a mouning plate (as we did it so far), we can contact the cantilevers now in a non-permanent manner. This allows to adjust the resonance frequency of…

February 2017: News from our Central Project Z2

Alexander Teplyuk (project Z2) had improved the head scanner with respect to scanning speed, robustness, and saftety means. It is ready now to be used for patient measurements. First evaluations have been performed in close cooperation with our medical project B5. The scanner has reached the next level ... Your browser does not support the video tag. Furthermore, a head…

October 2016: Enno Lage Received the DGM Young Researcher Award

Schematic of an magnetoelectric cantilever sensor the magnified region represents the layer stacking of piezolectric (AlN), and the self biased magnetostrictive stack (Ta, Cu, MnIr, FeCoSiB). The arrow represents the bias field orientation. For his work about magnetoelectric sensors in medical engineering Dr. Enno Lage, post doc at Kiel University, received an award for young researchers from the German Society…

September 2016: Patent on the Tuning-Fork Principle

Today (September 15th, 2016) the inventors Robert Jahns, Holger Runkowske, and Reinhard Knöchel were informed from the European Patent Office that their idea on the "tuning fork" sensor principle is protected now by the European patent EP 2 811 314 B1. Congratulations to the inventors! A "tuning fork" sensor basically consists of two ME sensors, which are arranged on top…

August 2016: New Sensitivity Record Obtained with Thin Film Resonant Sensors

Recently a new AlN deposition process was sucessfully established within the CRC 1261. Conventional sensors follow a certain deposition order, i.e. AlN-FeCoSiB, dictated by the temperature limitations of the magnetostrictive phase. This was overcome with the implementation of a low temperature AlN deposition process, which in turn allows the deposition of FeCoSiB as the first layer on the polished surface…
