Vibrations control and exploitation
The aim of the research group is to develop novel methods and devices useful to control and exploit vibrations. The focus is both on modeling/simulation and un experimental methods.
VIBRATIONS ENERGY HARVESTING FROM INDUSTRIAL AND NATURAL SOURCES
Nowadays remote sensors nodes can be fed by means of vibrations energy harvesters that scavenge energy from industrial or natural vibrations or by the action of wind, rain, and sea. The research focuses on the development, simulation and tuning of efficient piezoelectric harvesters.
MODAL ANALYSIS
Modal analysis methods are used in the field of vibration control with the aim of finding the component responsible for vibration transmission and in the field of vibration energy harvesting, with the aim of identifying the properties of new materials and tuning devices.
VIBRATIONS OF UNDER-ACTUATED ROBOTS
Underactuated robots have less actuators than joints and are an emerging technical solution in applications where the mass and the cost of components are important. The research focuses on motion of the non-actuated link, which is an oscillation excited by the motion of the rest of the robot.
