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.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
