New Project: Mold Detection

Mold is a big health issue and became more and more the subject of environmental medical investigations. The correlation between mold exposure and to some extent severe illnesses has been proven by several studies. Up to now, there is no reliable way to continuously quantify mold contamination. Because of the extensive and expensive laboratory-based analysis, it is often not determined at all or only sporadically. The aim of this research and development project is the realization of an automated sensor system for continuous measurement of mold contamination within industrial bio filter systems. For this, a novel micro-reactor-array will be designed, which allows autonomous cultivation and detection of mold spores.

The project is being funded by AIF/ZIM and runs for 2.5 years.

Monitoring dehumidifying of buildings damaged by water with an intelligent moisture-content measurement system

Different sensor technologies for measuring the moisture content in building materials will be evaluated, developed and tested. Sensor information will be used to monitor drying equipment after water-induced damages. Flooding repairs usually take several weeks and require large amounts of energy. Multiple checks by a technician might be necessary to determine when a sufficient drying state is achieved and the equipment can be switched off.

DFG-ANR Project “Tubular Bell” Kick-Off in Bremen

The German-French cooperation project “Tubular Bell” aims at a new class of phononic crystals, Tubular Phononic Crystals, and their application as a sensor, the Tubular Bell. Our vision is a fundamentally new sensor concept for in-line monitoring of liquids in cylindrical structures like pipes (chemistry) or vessels (medicine). The DFG and ANR funded project brings together research groups from the Université Pierre et Marie Curie in Paris, Université de Lille, Otto-von-Guericke-University Magdeburg, and University of Bremen, with the Kick-Off meeting held on 16.01.2019 in Bremen.

IMSAS presents new chip for 2-dimensional air-velocity measurement: Application during field test in cold storage warehouse

In many applications it is necessary to measure not only the magnitude, but also the angle of the air-velocity, e.g. for capturing the flow field in gaps or at surfaces. So far, two separate sensor chips were required to construct a 2-dimensional anemometer. The new IMSAS chip integrates 4 thermopiles placed with a small offset in ±x and ±y direction, close to a heater. Magnitude and angle can be calculated by the x and y difference signals. 

The first samples were processed in our clean room and put into service. The required chip area was reduced to 2mm by 2mm, i.e. only 60% of the initial 1-dimensional chip design. Now, only one square 2D chip is necessary instead of two 1D chips. In total, the required chip area was thereby reduced to one third. 

The new chip also enables more efficient housing and PCB designs. The sensor element can now be placed exactly in the center of the housing, resulting in an equal sensitivity in all four directions. 

The first test in our wind tunnel has shown that the new chip has a higher sensitivity at low velocities.  Nine Wireless Anemometers, equipped with the new 2D chip, were installed in a cold storage warehouse for apples during a field test in November 2017.
