Drivers know whether or not their cars are running properly by observing the dashboard. Physicians can check vital parameters such as the pulse even when their patients are at home. The data can be recorded with the wireless monitoring device VitaSENS.
The modern automobile relies on sensors to monitor the vehicle’s operating condition. Whether it’s the speed, RPM, open doors, oil pressure, coolant temperature or fuel level, the driver constantly receives information about the “health” and well-being of his car. Should he be unfortunate enough to land in the hospital himself, it is his own vital parameters that the attending physicians will need to check. Regularly measuring and monitoring vital signs like pulse, temperature or blood oxygen content can also be important in rehabilitation clinics, as part of post-therapy treatment at home, or during professional sports activities.
It was to meet this need that Fraunhofer researchers introduced the multi-sensory Body Area Network (BAN) four years ago. In the meantime, they have integrated a whole series of sensors in a single device and christened it VitaSENS. Optical sensors attached to the earlobe, finger or arm measure the blood oxygen saturation, heart rate and arterial pulse curve – the latter being the pulse wave generated by the heart muscle each time it contracts.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
