A force/torque sensor includes a ground unit having an internal space, a sensor unit positioned within the internal space and including a plurality of electrodes generating capacitances with the ground unit, and a support unit combined with a portion of the ground unit and supporting the sensor unit.

Force/torque sensor that miniaturization is available

Provided herein is a capacitive torque sensor, which can completely offset forces/torques in all axial directions, except for force/torque in a direction of a central axis, by measuring variations in capacitances of four sensing cells arrayed at angular intervals of 90 degrees on the basis of a center of the sensor and can offer a sensing value for the torque in a central axis direction.

Capacitive torque sensor without limit in flexure hinge

Disclosed are a multi-axial force sensor capable of measuring multi-axial force and a grasper for sensing multi-axial force using the same. The multi-axial force sensor includes: a first operating section which includes a first member, and a first protrusion module formed protruding from one side of the first member; an elastic section which is formed at one end of the first member; a second operating section which includes a second member formed with one end to face one end of the first member with the elastic section therebetween, and a second protrusion module formed protruding from one side of the second member to face the first protrusion module; and an electrode section which is formed in the first protrusion module. With this, there is provided a force sensor capable of precisely measuring force through a simple structure.

Multi-axial force sensor and grasper for sensing multi-axial force using the same

Provided herein is a method and apparatus describing a force sensor that includes a ground unit that is a grounded conductor that changes its position according to an external force, and including a flat panel module that is a conductor of a flat panel shape, and a protruding module that is a conductor protruding from a lower surface of the flat panel module, a substrate of a flat panel shape arranged in a predetermined distance from the lower surface of the flat panel module, and having a hole through which the protruding module may be inserted, a first electrode formed on an upper surface of the substrate, to generate a capacitance together with the flat panel module upon receiving power, and a second electrode formed on the substrate, to generate a capacitance together with the protruding module upon receiving power.

Force sensor and multiaxial force/torque sensor using the same

A capacitive type sensor includes a circuit board, electrodes formed on a first surface of the circuit board, and an electrode plate disposed above the circuit board, wherein the electrodes comprise pairs of electrodes disposed from a distance from a center of the circuit board, and the pairs of electrodes being spaced apart from each other.

Capacitive type 6-axial force/torque sensor

The present invention relates to a surgical grasper for measuring force, the surgical grasper having a first gripping part and a second gripping part, the first gripping part being provided with a first recess portion recessed inwardly from an outer surface of the first gripping part, the surgical grasper including: a first elastic dielectric body having one surface surface-contacting the first recess portion; an electrode part including a pair of electrodes opposed to each other on opposite surfaces of the first elastic dielectric body and having a distance between the electrodes, varied by external force applied thereto; and a first finishing part surface-contacting the other surface of the first elastic dielectric body and formed to correspond to the first recess portion to thereby be inserted into the first recess portion.
