Strain gages sensors for high stability piezo actuators

Space, military, and industrial applications require precision position sensors in order to perform closed-loop control or to monitor the state of a system. Those applications usually come with constraints such as wide thermal range, long lifetime, high stability, and compactness.


Nanometric positioning with piezo actuator and high stability strain gauges

Many applications require long-term position stability, which relates to the notion of absolute precision over time. Until now, the long-term stability of strain gages (SG) for position measurement was questionable. Using its extensive know-how of strain gages integration and new instrumentation equipment, Cedrat Technologies has managed to demonstrate nanometric position stability of a closed-loop piezo-mechanism with integrated strain gages sensors. This technology opens a wide range of new possibilities for industrial, aeronautical, and space applications.


AC magnetic field detection system applied to motion tracking

In the context of motion tracking and virtual reality, there is a strong need for sensors to monitor the motion of a moving object. These sensors are characterised by their performances (ranges, accuracy, drifts, and susceptibility to the ambient environment) and embedded (small size, light weight). The magnetic technology compared to the mechanical or optical solution allows the working without structural skeleton composed of links interconnected by monitored joints and with possible optical shadows.


Contactless Torque Sensors based on shaft torsion measurement, compatible with existing shafts

The torque measurement usually comes from strain gauges bonded on a shatf. the main concern in this measurement is due to the fact that these gauges are also rotating and the integration of electronic on rotating parts is definitely a blocking point.


Eddy current sensors on Printed Circuit Board for compact mechatronic application

In a contact of always smaller and smarter mechatronics devices, the needs of more integrated sensors becomes critical. Particularly, small mechanisms using small actuators like piezo actuators require compact sensors, with performances that measure up to the actuators characteristics.


Magnetic resonant sensors for remote identification of objects

This article deals with the use of Magnetic Resonant Sensors (M.R.S) for the realisation of an identification system. Nowadays, the market of I.D. systems evolves versus magnetic tags as they bring some advantages like remote identification and removal of the need of handling.
