Abstract
A system for detecting and locating a disturbance of a medium includes a medium for propagating bulk acoustic waves, a mechanism for emitting bulk acoustic waves in the medium, a mechanism for receiving the bulk acoustic waves after propagation thereof in the medium, configured to supply a reception signal from the acoustic waves received, and a mechanism for detecting and locating the disturbance in the medium from the reception signal. The medium includes a dermis layer of elastic material with a thickness locally deformable by the disturbance.

1-13. (canceled)
A system for detecting and locating a disturbance of a medium, comprising:
- a medium for propagating bulk acoustic waves;
- means for emitting bulk acoustic waves in the medium;
- means for receiving the bulk acoustic waves after propagation thereof in the medium, and configured to supply a reception signal from the acoustic waves received;
- and
- means for detecting and locating the disturbance in the medium from the reception signal;
- wherein the medium comprises a dermis layer of elastic material with a thickness locally deformable by the disturbance.
The system for detecting and locating a disturbance of a medium as claimed in claim 11, further comprising:
- means for measuring a damping, due to presence of disturbance, of the bulk acoustic waves propagating in the medium;
- and
- means for estimating contact surface area of the disturbance from the damping measurement.
