    Abstract: An apparatus with two anchors including a housing, a movable element, and a rotary element is provided. The housing includes a first expansion unit, a second expansion unit, and a linkage. First alignment structures are disposed in the movable element and anti-rotation structures are disposed in the linkage. When the movable element and the rotary element enter the housing from two ends and are coupled along an axis, the movable element and the rotary element can approach each other to expand the first expansion unit and the second expansion unit to form two anchors. The apparatus with two anchors secures a sensor in a variety of environments such as walls or machines. When the apparatus with two anchors fixes a sensor in a hole of a stamping machine, the impact force does not cause stress concentration on the sensor so as to improve the reliability of the sensor.

    Abstract: A ball screw with force sensor in radial direction including a screw rod, a screw nut, a plurality of balls, and a force sensor is provided. The screw nut has a cavity. The cavity is extended along a radial direction from an outer surface of the screw nut. The force sensor is disposed in the cavity of the screw nut, and the force sensor includes a stationary base and an elastic component. The stationary base includes a displacement restraint, and the elastic component includes a contact end and a fixed end. The displacement restraint is coupled to the cavity to prevent the stationary base from being displaced in the radial direction for fixing stationary base firmly in the cavity. The fixed end is connected to the stationary base, and the contact end contacts a bottom surface of the cavity in order to sense a force along the radial direction.

    Abstract: The disclosure relates to a force measurement device including central portion, fixing portion, first and second sensing portions, and first and second electromechanical elements. The first sensing portion has first natural frequency. The first sensing portion is connected to the central portion. The second sensing portion has a second natural frequency. The second sensing portion is connected to the first sensing portion and the fixing portion. The first electromechanical element is disposed on the first sensing portion to measure a first vibration amplitude. The second electromechanical element is disposed on the second sensing portion to measure a second vibration amplitude. When the central portion is subjected to a first force, the first vibration amplitude is larger than the second vibration amplitude. When the central portion is subjected to a second force, the first vibration amplitude is smaller than the second vibration amplitude.

The sensing portion includes a first and a second elements connected with each other, and at least one first and at least one second strain gauges. A first end surface of the first element is connected to the central portion, and a second end surface of the second element is connected to the outer ring portion.

When the first end surface is subjected to an axial force, a first strain of a first sensing region of the first element in the axial direction is smaller than a second strain of a second sensing region of the second element in the axial direction. When the first end surface is subjected to a first torque with respect to the axis, a first twist angle of the first sensing region with respect to the axis is greater than a second twist angle of the second sensing region with respect to the axis.
