Aim of the project is condition monitoring of Elastomer-sealing with integrated pressure sensors.

Read Set

The aim of project READSET (Reproduzierbare Applikation von drahtloser Sensorik in technischen Textilien für Faser-Kunststoff-Verbundbauteile auf Basis passiver RFID-Sensortags‘, i.e. ‘Reproducible application of wireless sensor tags onto technical textiles for fibre reinforced plastics, using passive RFID technology‘) is to develop a wireless, material integrated sensor node (often referred to as ‘sensor tag’)  for data acquisition inside a fibre reinforced plastic (FRP) component. Additionally, a system for automatic placement of the sensor node during FRP production is to be developed.

Functional additive fabrication of simple sensor systems

The additive fabrication of objects with electrical or magnetic functionality is still a challenge especially for smaller dimensions. We combine different 3D and screen printing techniques to showcase the possibilities of printing custom sensor elements and ‘smart’ parts in a simple way.

Ligand

Within the scope of the project, a long-term stable combustible catalytic micro gas sensor will be developed for detecting hydrogen of very low concentration. Metalic nanoparticles linked by organic ligands will be used as catalysts. Long-term stability will be earned by creating a homogeneous temperature field on a catalytic layer by optimizing the design of the microfabricated sensor. Along with long-term stability, the sensor will have low power consumption, high sensitivity, low response time and low cross sensitivity. The Project LIGAND is funded by the DFG - Deutsche Forschungsgemeinschaft.

SINA – Sensorintegration in Aluminium Cast

Project ?SINA“ - Sensorintegration in aluminum cast - piezoresistive sensors for the direct integration in aluminum cast will be developed. Integration taking place during the casting process produces a shape connection between sensor and component which allows the measurement of strain directly at the relevant place in the component.

Lecksensorik

Testing for impermeability and detection of leaks play an important role in the construction and installation of Heating, Ventilation and Air Conditioning (HVAC) systems and other kinds of equipment. In cooperation with the company ZILA GmbH from Suhl, IMSAS develops a sensor module which can be used for testing HVAC systems and gas pipe systems for leaks.

InAuKa II - Development of novel multi-contact floating microelectrodes for the neuroscience

InAuKa - “Interareal phase coherence as a mechanism for attention-dependent neuronal signal routing: A model-guided causal analysis using new, multi-contact floating silicon probes for intracortical chronic stimulation and recording in primates”.

The project works on characterizing basic dynamic properties while processing visual stimuli in the brain and on developing realistic models for mechanisms taking place. The project’s results are essential for the development of visual neural prostheses, which enable patients with complete blindness to have a visual sensation.

ProWaChip – BioProzesswasserchip

The ProWaChip project will develop a Bio-Chip for fast, on-site detection of bacterial contamination in drinkable and industrial water, whose detection principle is based on a high-specific hybridization reaction taking place within the microfluidic chip. The BioChip performs both the lysis and analysis of bacterial RNA in a single substrate. The BioChip will be developed to produce “On-line”, “in-situ” detection of two indicator bacteria (E. Colli and L. pneumophila), technique which constantly monitors the process water of industries, such the sugar production, and becomes functional in drink water systems in combination with AGIL-equipment.

ReDynForce

Using measurement, modeling and feedback control of dynamic forces in order to reduce wind turbines' dynamic forces.

The service lifetime of wind energy plants is diminished by strong alternating loads, which are caused by turbulences in wind flow. In future systems improved control algorithms will have to be used, in order to reduce alternating mechanical loads. This requires instant sensory information about a change of flow. The project ReDynForce is funded by AiF and investigates the possibility to implement acceleration sensors into the rotor to get this sensory information right at the beginning of an increased energy input. Based on this information an innovative control strategy will be developed at the FWBI under the direction of Prof. Orlik. 

Kammsensor

In the project ?Kammsensor“ an ultrathin (a few microns) dielectric sensor will be developed to monitor the product life-time of fiber reinforced plastics parts. For this task, the sensor will be embedded in the composite. The focus is on the curing process of the resin which can be measured on-line with this method. Due to the small size the sensor can remain in the composite without disturbing the material’s properties which make it possible to use the sensor also for structural health monitoring.

Intelligente Dichtung

Elastomerdichtungen finden in vielen Bereichen der Industrie (z.B. Hydraulik, Druckluft) aber auch im Anwenderbereich (z.B. Auto, Wasserleitungen) Verwendung. Obwohl es sich bei Dichtungen um relativ kleine, kostengünstige und unscheinbare Bestandteile eines Systems handelt, kann ein Versagen oft gro?en Schaden anrichten. Dieses Projekt hat es zum Ziel, Sensoren in Dichtungsringe zu integrieren, um eine permanente Zustandsüberwachung dieser zu erm?glichen, so Ausf?lle vorherzusagen und letztendlich zu vermeiden.

Based on an existing approach, the Microsystems Center Bremen (MCB) develops a thermoelectric flow sensor on a 10 μm thick polyimide foil. The result is a new thermal flow sensor on a thin film substrate which can be easily integrated into different shaped surfaces. The first prototype has been developed at the MCB. (PDF)

Thermal Flow Sensor

The Microsystems Center Bremen (MCB) develops thermal flow sensors based on a new high-temperature fabrication process. The key advantage of this new fabrication process is a high-temperature LPCVD (Low-Pressure Chemical Vapour Deposition) passivation layer that makes the sensor superior for liquid applications, such as in hydraulic systems, or for medical and biological sensing. These flow sensors are also excellent for measuring gaseous flow in pneumatic systems or for wind-speed measurement devices.
