LEONI research & development
The development of new materials, production processes and products is a permanent objective of our research and development. The impetus here is often provided by our customers’ current requirements. Our research and development areas enable us to help you continuously to optimise your products:
In addition to a wide range of standard materials for conductor insulation and cable jackets, LEONI also offers combined or new special materials, developed in its own materials research facility. The aim of our continuous research is to make it possible to unite the sometimes contradictory material properties in standard materials, thereby continuously optimising both our own products and those of our customers.
LEONI already produces and assembles a large selection of miniature cables for medical applications that place extreme demands on the level of miniaturisation, movement stress and maximum signal integrity. In response to the continuing trend towards increasingly smaller medical devices and systems and in an effort actively to develop these from the supplier side, LEONI also continues with its research work in the area of miniaturisation.
The aim of this research project at LEONI is to develop highly-sensitive force and pressure sensors on the basis of the so-called evanescent field characteristic of optical waveguides. This area of research has already given us the sensor for safety cut-out for medical devices.
Germ-killing plastic surfaces
Gaps in hygiene in hospitals and other medical facilities often lead to an increased risk of infection. LEONI aims to reduce these gaps with its innovative, antimicrobial cables. The cable’s jacket contains a special metal oxide that releases acid ions onto the cable’s surface to lower its pH level – in a very similar way to the way in which the skin’s acid protective layer works. The cell functions of the bacteria are disrupted and they die off. The decisive benefit offered by LEONI’s process is that the antimicrobial effect is not reduced through use. LEONI’s antimicrobial cables are used in x-ray, mammography, MRT and CRD devices as well as for dental equipment.
Silicone cable extrusion
Silicone is an ideal material for medical-technology applications in near-patient use. Almoust no other plastic as a cable jacket offers comparable advantages for medical users and patients: extreme flexibility in all directions, skin tolerance, biocompatibility and autoclavability with temperature resistance of up to 143 °C. Only its stick-slip effect leads to unwanted adhesion, for instance on patients’ skin or operating tables, and calls for special production methods to minimise this effect. LEONI’s patent-pending extrusion method equips silicone cable surfaces with better gliding properties without compromising the material’s other beneficial characteristics.
