Abstract
An intracortical-detection device including: at least one electrode that contacts a group of neurons; a first body, forming a surface that contacts a portion of a cerebral region; a first motor that moves the electrode with respect to the first body; a second motor; and a second body, operatively connected to the second motor, the first and second bodies being able to slide with respect to one another in a first direction, under the action of the second motor. The detection device moreover includes a sensor generating an electrical signal indicating a pressure exerted by the portion of cerebral region on the surface.
Claims8
An intracortical-detection device comprising:
- at least one electrode configured to contact a group of neurons;
- a first body, forming a surface configured to contact a portion of a cerebral region;
- a first motor configured to move said at least one electrode with respect to said first body;
- a second motor fixed with respect to said first body;
- and a second body, operatively connected to said second motor, said first and second bodies being able to slide with respect to one another in a first direction, under the action of said second motor;
- a sensor configured to generate an electrical signal indicating a pressure exerted by said portion of cerebral region on said surface;
- a crank, which is coupled to said second body and can be driven in rotation by said second motor about a second direction transverse with respect to said first direction;
- and a constraint configured to prevent motion of said first body with respect to said second body in directions different from said first direction;
- wherein said sensor comprises a transducer arranged on said crank and configured to vary an own electrical quantity as a function of a deformation of said crank caused by the pressure exerted by said portion of cerebral region on said surface.
