Abstract: A multi-axis force sensor including a central portion, an outer ring portion, and at least one sensing portion disposed along an axial direction of an axis is provided. 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. A normal vector of the first end surface is parallel to the axis and the axis passes through a centroid of the first end surface. 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.

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 fonn 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.
