Fraunhofer researchers have succeeded in using the bioresorbable silica gel Renacer® to produce an electrospun membrane that is neither cytotoxic to cells nor genotoxic. This model mimics fibrous structures found in connective tissue and is therefore particularly suitable for regenerative applications, such as for improved wound healing.

Drones are operating increasingly in areas out of sight of the person controlling them. However, conventional remote controls have a limited range, which makes them unsuitable for these flights. On the other hand, simple mobile network-based systems have so far been unable to guarantee a reliable connection when mobile network loads are high or where there is a lack of network coverage. Researchers at the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut, HHI have joined forces with partners in the SUCOM project to develop a new mobile network system that can be used to control drones even over long distances and over difficult terrain.

In the “smood® — smart neighborhood” project, sixteen companies, four research institutions and an association have been working together, with the scientific support of Fraunhofer, on the future of energy-related renovation measures over the past few years. Covering everything from digitalized planning processes and innovative district storage systems for electricity and heat to intelligent control and operational management solutions, the project aims to ensure that existing district facilities are ready for the energy transition — and that tenants benefit from lower costs of living as a result.

They are barely the size of a thumbnail, able to communicate with each other and respond to each other, and designed to make life easier for people with functional limitations. We are talking about a new generation of interactive microimplants developed by the innovation cluster INTAKT, which is funded by the German Federal Ministry of Education and Research (BMBF) and coordinated by the Fraunhofer Institute for Biomedical Engineering IBMT. These miniature assistants can act as a stimulus in cases of tinnitus or digestive tract disorders or help a person’s hand to regain the ability to grip.

Programmable materials are true shapeshifters. They can change their characteristics in a controlled and reversible way with the push of a button, independently adapting to fit new conditions. They can be used, for example, to make comfy chairs or mattresses that prevent bedsores. To produce these, the support is formed in such a way that the contact surface is large which, as a result, lowers the pressure on parts of the body. This type of programmable material is being developed by researchers at the Fraunhofer Cluster of Excellence Programmable Materials CPM, who plan to bring it to the market with the help of industry partners. One of their goals is to reduce the use of resources.

The energy market is undergoing a major shift, with renewable energies booming and the number of connection requests rising sharply due to funding programs for solar plants, heat pumps and electric vehicle charging stations. The new cloud software retoflow offers energy network operators an automated and efficient way to check these requests, model and simulate power grids and pipeline networks across sectors, and engage in long-term planning. This user-friendly program has been developed by the startup retoflow GmbH, a spin-off of the Fraunhofer Institute for Energy Economics and Energy System Technology IEE.

The factories of the future have significant demands to meet – including the ability to adapt to production processes quickly and function within tight spaces that come at a high operating cost. Mixed reality can provide efficient support for factory planning in exactly this kind of scenario. Through their HoloLayouts software, researchers at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA have developed an application in which multiple people can collaborate interactively on creating factory layouts that use space efficiently. The factory planning process can be experienced in a virtual environment, with changes made live and in real time.

Used and damaged cars are often disposed of via energy-intensive scrapping processes — even when many of their parts are still fully functional. In the EKODA project, Fraunhofer researchers are developing a better alternative: First, they examine each component in a complex testing procedure. Then they use an evaluation system to generate recommendations for how these components could be reused. This strategy optimizes the lifespan of the individual parts, making it possible to establish a sustainable circular economy in the mobility sector. Used batteries, gear shafts and cogwheels could even show up in other applications outside the automotive industry.

Warehouses are home to heavy volumes of traffic. The numbers of industrial trucks (pallet trucks, forklift vehicles and the like) traversing their aisles are growing especially large – in facilities that are themselves increasing in size all the time. Under these conditions, accidents become an inevitability even if numerous safety measures are put in place. Now, optical sensors on industrial trucks might provide warehouse staff with better protection as they do their jobs. Joining forces with BASF and Kinotex Sensor GmbH, the Fraunhofer Application Center for Optical Metrology and Surface Technologies AZOM has developed prototypes designed to ensure added safety during day-to-day activities.

In the human body, electrolytes play a key role in maintaining water balance and distribution of fluids. All charged particles dissolved in the blood interact with each other. If a disturbance to their complex equilibrium is suspected, the concentration of a variety of these microminerals will be analyzed. Researchers from the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut, HHI and partners from a variety of disciplines have joined forces as part of the optION project. The project goal is to develop a device concept that uses a photonic sensor solution to significantly reduce the amount of blood needed for analysis and make the testing process significantly easier for all those involved.
