Semiconductor sensors, spectrometers as well as components from the Institute are used in the automobile industry, environmental analysis, building technology, safety technology or medicine technology – tailored, robust and energy-efficient. Current developments in gas sensors and thermoelectrics can be found on the Sensor+Test 2010 in Hall 12, stand 202.
The safety and quality in the food supply of today’s globally organized and networked supply chain is everything else than warranted. More than 50% of all foodstuffs are spoiled in the transport routes; alone in Great Britain this makes up 17 million tons and approximately 20 billion Euros. Intelligent measurement techniques – specifically applied – can sustainably save energy resources. Inside the Fraunhofer »Food Chain Management« Alliance, Fraunhofer IPM is developing different measurement systems for the online monitoring of foodstuffs. The use of gas chromatography in connection with metal oxide semiconductor sensors permits economical online control of processes in the food industry. A combination of gas chromatography and an optical ethylene measurement system monitors the quality of foodstuffs and safety for fruit, vegetables and also fresh meat. In a banana storage unit or container, the climatic technology can be efficiently controlled on the basis of the determination of the ethylene concentration, and this also applies to greenhouses.
Economic control of the transport routes of perishable goods
Since the start of last year, in collaboration with European partners in the »RFID Pro¬Active Cold Chain« project, the Fraunhofer IPM has been developing UHF-RFID tags with integrated sensoring in order to seamlessly document the transport routes of perishable goods such as medications, especially vaccines or foodstuffs. Moisture sensors also prevent rusted steering axes and help to save time and energy in this way. Temperature sensors are meant to sense the surroundings quickly and without contact, and thus control the climate technology in an as energy-efficient manner as possible. For instance, they raise the alarm as soon as the cooling chain is interrupted.
Clean air: Imission monitoring
Fraunhofer IPM is also active in imission monitoring. Besides optical systems for determining methane, the gas measurement system includes electrochemical elements for detecting ozone and CO; as well as semiconductor sensors, and temperature and moisture sensors. The aim is to create a mobile dynamic environmental cadastre for recognizing pollutant concentrations and counteracting them. With the aid of this complete measurement system, an important contribution is made towards achieving climatic protection goals and implementing the Air Pollution Regulation.
At the Sensor+Test 2010, Fraunhofer IPM is exhibiting sensing RFIDs, compact gas measurement systems, e.g. for ethylene, or gas sensor arrays for detection of gases and gas mixtures, as well as a gas-sensitive metal-oxide thin-film transistor. Interested parties can also inform themselves on measurement systems: a light source for infra-red spectroscopy, multi-reflection cells and fast modulating IR emitters for the 5 ìm to 12 ìm wavelength range.
Future technology thermoelectrics: energy-autonomous systems use waste heat.
More than 60% of the overall used fossil primary energy is wasted as unused heat energy according to a study of the Lawrence Livermore National Laboratory. Thermoelectric generators are able to utilize the energy portion of lost heat – at least partially – for instance, in firing plants in industrial processes, and especially in the automobile, and convert it into electric current. That this works is shown in thermoelectric generators in space where they have been used for decades as extremely reliable suppliers of energy for probes and satellites – emission-free, silent and vibration-free. Fraunhofer IPM is demonstrating this with a Carrera track, at which visitors can take part in car races. The model racers are powered by thermoelectric generators of bismuth or lead telluride. Moreover, energy-autonomous radio sensors use waste heat and thus cover many applications. In the car they can help to save weight as heavy cables are superfluous. The sensors also aid with monitoring old buildings. They can simply be stuck to the walls where, for example, they measure the moisture. They are even applicable in the field of medicine. In this way, sportspersons can measure their pulse via a sensor system built into their T-shirts, or use hearing aids which obtain their power from body heat.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
