Sensor stickers transform the human body into a multi-touch surface

08-May-2018

They are similar to ultra-thin patches, their shape can be freely chosen, and they work anywhere on the body. With such sensors on the skin, mobile devices like smartphones and smartwatches can be operated more intuitively and discreetly than ever before. Computer scientists at Saarland ...

Turning polymer films into self-sensing high-tech actuators

28-Mar-2018

They might only be made from thin silicon film, but they can squeeze down hard, deliver a powerful thrust, vibrate or hold any required position. And because they can act as sensors, they are becoming important tools in technical applications. Stefan Seelecke and his team at Saarland University ...

Measuring mechanical properties of 2D monolayer materials

19-Jan-2018

The thinnest materials that can be produced today have the thickness of a single atom. These materials – known as two-dimensional materials – exhibit properties that are very different compared with their bulk three-dimensional counterparts. Until recently, 2D materials were produced and ...

Ultrathin superconducting film developed

10-Apr-2017

Experimental physicists in the research group led by Professor Uwe Hartmann at Saarland University have developed a thin nanomaterial with superconducting properties. Below about -200 °C these materials conduct electricity without loss, levitate magnets and can screen magnetic fields. The ...

Flow phenomena on solid surfaces

Boundary layer velocity plays key role

12-Feb-2016

This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics. When liquids flow over solid surfaces, their flow ...

Polymer nanoparticles used as drug carriers characterized using Nanoparticle Tracking Analysis

13-Feb-2013

NanoSight reports on how Nanoparticle Tracking Analysis, NTA, is used to help with the characterization of polymeric nanoparticles synthesized as drug carrier systems. This work is being carried out at Saarland University by Dr Christian Ruge and his colleagues. In the world of pharmaceutical ...

Oil change due? Optimal date is to be determined during normal operation

16-Apr-2010

If lubricants and hydraulic fluids in construction machines, airplanes or industrial installations are used too long, gears and other components can be heavily damaged. On the other hand, each oil change especially for large equipment is time consuming and expensive. Engineers at Saarland ...

Scent or stench? Odors of diapers and aroma compounds can be measured objectively

08-Apr-2010

For consumables like diapers and also for many foodstuffs the smell is a very decisive factor. Consumers can be convinced more easily, if it smells good. And also during the use of the product the smell is essential. Today, the human nose is still the best gauge to determine which product is most ...

Researchers want to accelerate the scanning probe microscope

07-Apr-2010

Since more than twenty years, scanning force microscopes are employed in research and industry. Their enormous resolution triggered many applications in nanotechnology. Their rather low image rate is however a disadvantage - changing objects and processes cannot be imaged. Physicists of Saarland ...
