Integrated Flex Pivot Position Sensor
There is a current trend towards using tribology free mechanisms where possible, to avoid complexities such as stick-slip behaviour and noise due to sliding contacts. These trends have led to the ongoing development of promising Large Angle Flexible Pivots, the deflecting behaviour of these pivots presents opportunities to unlock further advances in the area of sensors.

Improvement of microvibration prediction and verification methods

This activity is split in different parts focusing on various aspects of the overall methodology: 1) Models and structural analysis development, fidelity and coupling: Noise source models are the starting point of microvibration analysis. Some sources are well known and modelled (e.g. Reaction wheel) but others still require some development. In particular, cryo-cooler and stepper motors models are often key to microvibration performance but are generally based on black-box models coming from test characterization without a model representation of the physical phenomena.

Optical Compressive Sensing(CS) technologies for space applications

The project aimed to design an optical instrument based on Compressive Sensing (CS) for a space applications. Conventional sampling or compression methodologies follow the Shannon-Nyquist theorem, which states that if a signal frequency band or spectrum is limited to a frequency B [Hz], the signal is completely determined by a sample-rate larger than 2xB samples per second. Compressive Sensing (CS) provides a fundamentally new approach to data acquisition or signal sampling.

Autonomous Medical Monitoring and Diagnostic

Global plans for exploratory missions aim at extending the distances travelled by humans well beyond low Earth orbit and establishing permanent bases on the surface of Moon and Mars [1]. This will inevitably lead to increasing mission duration, radiation intensity, gravity levels and degree of confinement and isolation to which the crews will be exposed. In this extended space mission context, the astronauts should have the means to collect medical/physiological data in order to understand if their physiological conditions are in nominal levels.
