Test

Specialised test equipments available at CEDRAT Group are also recommended to build electromechanical & piezoelectric devices:

• Impedance analyser is used for measurement of admittance curve, resonance and equivalent circuits
• Laser interferometers are useful to measure the actuators' speed and main displacement as well as parasitic displacement with high precision
• The Thermal Vacuum chamber allows the analysis of thermal behaviour (from 70 to 400 K) and/or the effects of primary or ultra vacuum (10-6 Torr)
• Climatic room
• Force bench to characterise the actuators' stiffness
• An electromagnetic shaker to test a mechanism in vibration
• A lock-in amplifier to perform precise measurements under a noisy environment
• Magnetic bench for fast characterisation

All prototyped and standard devices highly benefit from these equipments.
