Gone are the good old days when farmers knew all their cows by name. There is little time left for the animals in today’s dairy industry. And it is easy to overlook the first signs of disease.
This situation can now be remedied by a tiny sensor in the cow’s rumen, which monitors the animal’s state of health and raises the alarm in good time. The system determines the pH level and the temperature inside the cow’s rumen. The data are wirelessly transmitted to an external receiver module in the animal’s collar via an encapsulated measuring probe. A network of sensors forwards the signals to a central database. The farmer immediately receives a warning if the readings are above or below a reference value. At present, the pH level in the rumen can only be measured via pharyngeal probes.
Scientists from the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg have developed the new system, which they can also adapt to numerous other applications in agriculture and forestry. The network nodes contain all of the components needed for connecting sensors and actuators. Radio modules of this kind have a long service life due to their low energy consumption. They are capable of autonomous networking, and do not require supervision or a special infrastructure.
The system is a joint development by partners in Germany and the Netherlands. The cross-border project is co-financed by the EU program INTERREG IIIA in the Rhine-Waal region, the Ministry of Economic Affairs and Energy of the State of North Rhine-Westphalia, and the Gelderland province. The new measuring system is slated to go into service as of mid-2008, and will be tested on pilot farms run by the Lower Rhine Chamber of Agriculture and in other research establishments.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
