Abstract: The disclosure relates to a load cell including an elastic element, at least one strain gauge and a limitation element. The elastic element includes a first end portion, a second end portion and a deformation region. The first end portion and the second end portion are arranged along an axial direction and opposed to each other. The deformation region is located between the first end portion and the second end portion. The at least one strain gauge is disposed in the deformation region. When a force is exerted on the first end portion in a first direction, the deformation region is deformed to drive the at least one strain gauge to change shape, so that the force is measured and standardized under a specific range. The limitation element is connected to the elastic element. A gap is formed between the limitation element and the elastic element.

Abstract: The disclosure relates to a linear actuator including a base, a linear motor, a load cell and a rotary motor. The linear motor is disposed on the base and includes a fixed coil module and a movable magnetic backplane. The fixed coil module is fixed on the base, and the movable magnetic backplane is configured to slide relative to the fixed coil module along a first direction. The rotary motor is rotated around a central axis in parallel with the first direction. The load cell has two opposite sides parallel to the first direction, respectively. The movable magnetic backplane of the linear motor and the rotary motor are connected to the two opposite sides of the load cell, respectively. The load cell is subjected to a force applied thereto by the rotary motor and parallel to the first direction, and configured to convert the force into an electrical signal.
