Abstract: Disclosed is a force sensor and an apparatus having the sensor for measuring weight. The force sensor and apparatus can enhance detection sensitivity by amplifying a displacement of an elastic body having high strength, thereby measuring weight. The sensor includes: a base; an elastic structure provided as a housing disposed on the base, and downwardly deformed when weight is applied to the elastic structure; an adjusting member coupled to an upper surface of the elastic structure by penetrating the upper surface; a lever disposed below the elastic structure, and amplifying a displacement of the elastic structure transferred via the adjusting member by being in contact with the adjusting member; a sensor disposed above the base, and generating an electric signal indicative of a distance from the sensor to the lever; and a circuit board disposed between an upper surface of the base and a lower surface of the sensor.
Abstract: Disclosed herein is a multi-axis force sensor which includes a vertical measurement module to measure a vertical component of force applied to a point of application, and a horizontal measurement module to measure a horizontal component of force applied to the point of application, wherein the vertical measurement module has a body horizontally moved by the horizontal component of force applied to the point of application, and the horizontal measurement module measures the horizontal component of force applied to the point of application, based on the movement of the body of the vertical measurement module.
