This laboratory is equipped with software and instrumentation for the design and the characterisation of functional elements, prototypes and devices.
The lab allows the set-up of non-conventional experimental test benches for different applications by the combined use of facilities such as: Labview-controlled virtual machines, AC/DC voltage or current sources, cooling systems, thermostatic baths, a thermostatic/climatic chamber, load cells and linear/rotary displacement transducers.
In addition, a workshop for the machining of mechanical parts as by turning and milling is available for the preparation of holders, supports or components used in the implementation of special experimental set-ups complementing the standard characterisation machines.
Furthermore, software including 2D/3D CAD systems, Comsol Multiphysics, Labview and Matlab, is frequently used for the design, the simulation, the control of the devices and the analysis of signals and bio-signals.
In addition, the lab includes a 3D printer for fabricating components of actuators, sensors and devices in ABS co-polymer.
