Microelectromechanical systems (MEMS) have been already successfully commercializedudfor around 20 years. The design of novel MEMS sensors currently targets two important features:udsmaller dimensions and higher reliability. As the characteristic size of the mechanical componentsudof the devices decreases, uncertainties in the mechanical and geometrical properties inducedudby the microfabrication process become more and more important. To address these issues,udan on-chip testing device has been proposed to avoid any visual inspection for the read-out.udThe electromechanical responses of ten nominally identical specimens have been recorded, andudexperimental data have shown a significant scattering due to the presence of relevant uncertaintyudsources. To interpret the response of the device, an analytical reduced-order model of the wholeuddevice has been developed. A genetic algorithm has then been adopted to identify features of theudmechanical and geometrical uncertainties in the batch of test structures.
