Tip-tilt mechanism

White paper: long-stroke/high-resolution tip-tilt mechanism downloadweblink

Cedrat Technologies S.AMon, 4 Aug 2014

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.

Amplified piezoelectric actuator APA with composite shell

Technical article: compact and efficient piezo actuation chain for aeronautical applications download

Cedrat Technologies S.AMon, 28 Jul 2014

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.

Cryo-characterisation test bench

White paper: cryogenic piezo characterisation and integration download

Cedrat Technologies S.AMon, 21 Jul 2014

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. 

MICA actuator on test

Technical article: MICA — performances in closed-loop control download

Cedrat Technologies S.AThu, 17 Jul 2014

In this article, Cedrat Technologies presents the moving iron controllable actuator (MICA) and its characteristics under closed-loop control operations. MICA is a magnetic actuator with a high-density force, a low-mass moving part and the capability to inverse the force with the inversion of the current. The guiding is made of blades and thus avoids friction that would introduce hysteresis.

The second harvester prototype

White paper: a bistable piezoelectric harvester for wideband mechanical frequency excitation download

Cedrat Technologies S.AWed, 9 Jul 2014

Embedded systems are increasingly used in industrial applications. The energy supply is a key point for the development of such systems. Solutions based on battery have limited lifetime and the power supplies through wires are not always appropriate and easy to install. Furthermore, the battery recycling is complex and an expensive process. This paper focuses on a bistable harvester designed and invented by SYMME using APA technology.
