Igus has launches an accessory for e-chains and e-tubes: the CFV strain-relief element. This offers users the chance to relieve cables of strain outside of the chain cross section, even in enclosed energy tubes. The CVF ensures that cables within the moving e-chain do not move around when moving. In addition, with a stepped design to secure cables of different diameters, it ensures simple installation when strain relieving several cables.

An Igus energy chain system has recently been designed into the largest capacity rail traverser in the UK.
Induction is a process by which a magnetised or electrically charged object produces magnetism, an electric charge or an electro-motive force, in another object without being in contact with it. These processes are called magnetic induction when magnetism is produced, electrostatic induction when an electric charge is produced and electromagnetic induction when an electric voltage is produced. This article from Gill Research & Development discusses each of these.
Technical article: a new rotating voice coil motor for Meteosat third-generation satellites download
The goal of this paper from Cedrat Technologies is to present the motor that meets the requirements of the Meteosat third-generation satellite system.
Multi-degree-of-freedom (DoF) mechanisms are widely required in micro or macro manipulation fields as well as in optronics functions. Commonly available mechanisms may be divided into two main categories. The first is industrial robots (serial or parallel). These offer a large range of motion in rotation and translation. Their resolution is usually limited in the sub-millimetre range.
Technical article: compact and efficient piezo actuation chain for aeronautical applications download
Many past and ongoing studies are focusing on the use of piezo-actuators for aeronautical applications. One of the trendiest topics is the use of such devices for active flow control in aircraft in order to reduce fuel consumption and noise. However, the implementation of such systems in aircraft suffers a lack of maturity with respect to aeronautical constraints, which are high efficiency, compactness and light weight.
This paper details a test bench design and the results obtained with CNES on two-piezo ceramics stacks from two distinct suppliers. Integration into dedicated cryo actuators is also proposed as well as the associated cryo performances. The use of such cryo-compatible actuators is detailed in a fine steering tip-tilt mechanism designed to reach very high resolution and stability for the ESA EChO space mission.
