Bionic Acoustic Camera
Hearing with your eyes - the Acoustic Camera  a portable system that can be used to visualize sounds and their sources. Maps of sound sources that look similar to thermographic images can be prepared in minutes.
Bionic propeller
With their fanned wing tips, birds already use it longer than the age of mankind, and avionics made the retrofit in the last years. The topic is the principle to split up vortices at the wing tip, known as "winglets" in airplanes. The consequent further development in aero- and hydrodynamic terms led to a stunningly simple, but even more stunningly efficient propeller.
Self-cleaning surfaces: the Lotus-Effect
One of the best-known examples of bionic research is the so-called Lotus-effect® discovered by Wilhelm Barthlott in the mid 1970s. He noticed that the surfaces of unwettable plant leaves are rarely soiled. This feature could be observed in many plants that are covered in minute wax structures, in particular with the lotus flower (Nelumbo nucifera), a symbol of purity in Asian religions.
S2C modular modem series presented to broad public
The new modular modem series was presented to the broad public for the first time at OTO’04 in Kobe, Japan. The market’s most advanced underwater telemetry, including the incredible fast and robust S2C signal processing, is offered in a flexible design for easiest integration into marine systems.
Optimization methods modelled after growth patterns of trees and bones
Based on observations on the growth forms of trees and other mechanically heavily loaded natural structures like bones, Claus Mattheck of the Institute for material sciences at the research center derived general rules for their shaping. He could demonstrate that structures can meet the demands of strength if the same stresses are acting all along the entire surface. The hypothesis of constant stresses was already put forward in 1893 by K. Metzger, a forrester, who applied this hypothesis on spruce trunks. Such a construction guide line leads to the development of things like trees, bones, teeth and claws with a minimum of material used and a maximum of loadability, while avoiding local weak points. Based on his studies of natural structures, Claus Mattheck devised several computer methods for shape optimization of technical parts. They are very successfully employed by the industry for more than a decade.
