In this research area micro-sensing technologies and components for microrobotics are investigated. Tactile sensing at the microscale is addressed taking inspiration from the biological models identified in the other research areas. Different technologies (both silicon and non-silicon based) are investigated with the driving objective to focus on those that allow the integration microarrays of sensing elements that can encode dynamic and static tactile information, such as that related to texture and contact forces for a smart microrobot. The approaches that will be identified will be characterised by a high level of integration of the sensing principles with their interface with the environment and processing electronics. The final aim is to integrate the new sensing systems into microrobots that are designed taking inspiration from relevant biological models investigated in the microrobotics research areas.
