A message from Gerald Murauer, Executive Director of SAL

I am very proud that SAL leads and coordinates a H2020 project for the first time. SAL has already been a project partner in the past but it’s the first time that SAL is in the lead. Within the project AEROMIC, SAL works together with industrial and scientific partners to develop an innovative sensor technology for aeroacoustic measurements based on high performance MEMS microphones integrated as microphone arrays, and the development of a compact smart sensor surface through the integration of sensors and electronic components using vertical integration technology. While these are challenging times, we keep moderately growing and creating new innovative solutions for technologies of tomorrow.


SAL leads first H2020 project AEROMIC

Together with Technische Universität Berlin (Germany), Vectoflow GmbH (Germany), USound GmbH (Austria), University Carlos III de Madrid (Spain) and Universitetet i Sørøst-Norge (Norway), SAL is working on the project AEROMIC. The project, which is part of the Horizon 2020 funded Clean Sky 2 Program, aims at developing an innovative sensor technology for aeroacoustic measurements based on high performance MEMS microphones integrated as microphone arrays, and the development of a compact smart sensor surface through the integration of sensors and electronic components using vertical integration technology.

AEROMIC aims to develop two types of new digital MEMS microphones to fulfil the stringent requirements for wind-tunnel tests and flight tests, respectively, and then integrate those MEMS microphones into large arrays for the accurate measurement of unsteady pressure fluctuations underneath the turbulent boundary layer, which can be applied to predict the cabin noise excitation. The project is coordinated by SAL. 

Smallest particle sensor made in Graz
It is smaller than a coin, particularly energy-efficient due to its size, requires no maintenance and can be integrated in smartphones, smart watches or fitness wristbands: This is the tiniest sensor in the field of airborne particle detection.
Smallest particle sensor

The goal of the ParticleSens project was to develop a highly integrated all-in-one sensor for detection of PM2.5 aerosol particles. The project was funded by FFG and executed together with ams AG and TU Graz. Jaka Pribošek, Senior Scientist in the research unit Photonic Systems, leads this project at SAL.  

In the first part of the project, SAL was responsible for system design considerations, performing optical simulations including ray-tracing and wave-optical simulations, implementing analytical Lorentz-Mie scattering simulations for aerosol particles, as well as CFD simulations for the design of microfluidics.In the second part of the project, SAL has developed and implemented a novel photonic system integration process to fabricate and assemble the sensor within the specified tolerances.

This little sensor could inform users in real time about the fine dust content of the air and warn in case of increased values. With this breakthrough, personalized particle detection could be made possible and this could be an important step in improving respiratory health.

Hemp, flax and nettles as new high-tech components
Natural fibers from hemp, flax or nettles are not only processed in textiles. This is demonstrated by SAL in cooperation with the wood research center Wood K plus and the Carinthian University of Applied Sciences. Research is being conducted on the use of these renewable raw materials in longboards, aircraft components or knee prostheses, for example, and on how these products can be linked to new technologies. All of this is taking place within the framework of the EU projects "Smarter Lightweight 4.0" and "NoWaste", the former being one of the 25 Austrian showcase projects chosen to mark "25 years of Austria in the EU".

SAL participates in this research project at the Villach location in the research divison Sensor Systems. Specifically, we are responsible for developing the innovative sensors which are integrated into natural fiber reinforced materials. "Due to their low thickness, printed sensors are laminated into material parts and can thus monitor the manufacturing process and mechanical stability in the application", says Lukas Rauter, Junior Scientist in our research unit Sensor Applications.

Project call for cooperative research: CAPSENS - Wafer Level Hermetic Capping for MEMS Sensing

The aim of the project is to create a reliable hermetic wafer-level packa­ging for MEMS sensors in order to increase the life-span of sensors in consumer & automotive applications, reduce cost and footprint of sensors, and faciliate the development of novel sensors on wafer-level.

Partner call open until end of November 2020

SAL presents papers at EMC Europe Conference
Ralph Prestros and Herbert Hackl from the research unit EMCC presented their co-written papers at the virtually held EMC Europe Conference.

"Benchmark for the Near-Field Problem: Simulation versus Measurement" was the topic of the paper written by Ralph Prestros, Karl Hollaus, Bernhard Auinger (all SAL) and Michael Leumüller (Vienna University of Technology). This paper evaluates how exactly impedances and the near field around a typical housing of an electronic based system with openings can be simulated. Two variants of the device under test (DUT) representing typical electronic device housings with balanced and unbalanced feeding were built and simulated. The 3D finite element simulation results showing the electric field strength and impedance plots are compared to near-field and impedance measurements. The results should give a feeling how exactly the shielding effect on the near field of an electronic housing can be simulated.

Herbert Hackl, together with Martin Ibel, Bernhard Auinger (all SAL), Dominik List and Christian Stockreiter (ams AG), published the results of the "Non-Destructive Modeling of a 9V Alkaline Battery for EMC Simulation Based on S-Parameter Measurement". Batteries are fundamental components of many modern systems, most prominently electric vehicles (EV) or mobile devices. Hence, generation of battery models is becoming a crucial task to evaluate the performance of suchlike electronic systems in simulation, including electromagnetic compatibility (EMC). But even commercial cells like a 9V block battery may critically impact daily EMC measurement tasks, namely if they are used for powering tested devices or peripheral equipment. To depict the battery’s influence by simulation, a model of selfsame suitable for 3D simulation with commercial software is developed. It is validated by two practical experiments and eventually applied to reproduce results of a bulk current injection (BCI) test.
Virtual Conference

Herbert Hackl gives talk at EMV Symposium
Herbert Hackl (SAL EMCC) and Dominik List (ams AG) gave a presentation on BCI simulation at the 18th Austrian EMC online symposium.Their lecture was intended to show practical problems of the simulation of EMC measurements using the example of the BCI test according to ISO 11452-4. The main problem areas are:
  • the determination of the relative permittivity of the support material (PU rigid foam),
  • the modelling for cable harnesses (equivalent, effective permittivity of the cable shield),
  • 3D modelling of the BCI sample, frequency dependence of the permeability of the ferrite core and
  • the influence of the battery supply at the DUT on the measurement result
They discussed the influence of the above parameters by means of practical experiments and also presented models for illustration in the simulation.In addition, research results from an ongoing project between ams AG and Silicon Austria Labs GmbH were presented.
