A sensor arrangement for measuring a mechanical loading, comprising a first member to be mechanically loaded; a first sensor component arranged on the first member; a printed circuit board (PCB); a second sensor component arranged on the PCB and spaced from the first sensor component, wherein an output signal of the second sensor component is indicative of the distance between the first and second sensor components; and an electronic component arranged on the PCB and configured to receive the output signal of the second sensor component, wherein the sensor arrangement is configured such that the distance between the first and second sensor components depends on the mechanical loading applied to the first member.

A load cell for installing in a weighing foot is described with a spring body, a measuring transducer for generating an output signal corresponding to a weight acting on the force introduction element, and an external interface connected to the measuring transducer. The spring body can have an outer support ring, a force introduction element, and an annular deformation section, the support ring and the force introduction element being connected with the annular deformation section. The external interface can output the output signal generated by the measuring transducer to an external device. The external interface for the external output of the output signal is provided at the force introduction element.

A pedaling sensing device of an electric bicycle is configured to connect to a motor and includes a crank axle, a first gearwheel disposed around the crank axle, a second gearwheel disposed around the first gearwheel, a sensing unit, an assisting unit, and a chain wheel. The crank axle has first bevel teeth, and the first gearwheel has a first transmission structure and second bevel teeth matching the first bevel teeth. The second gearwheel has a second transmission structure matching the first transmission structure. When the crank axle is driven by a force to rotate, the first gearwheel, second gearwheel and chain wheel are carried to rotate. The first gearwheel also moves with respect to the crank axle along the axial direction, so the sensing unit can sense the applied force. Then, the motor drives the assisting gearwheel and chain wheel to rotate, thereby achieving assisting riding effect.

A device for measuring a pressure of a vehicle closure member includes a pressure sensitive tip, a base, a plurality of electrical conductors, and a neck. The pressure sensitive tip is configured to output an electronic signal that corresponds to a pressure at the pressure sensitive tip. The electrical conductors electrically couple the pressure sensitive tip to the base. The neck includes an inner layer and an outer layer. The inner layer is disposed about the electrical conductors. The outer layer is disposed about the inner layer. The neck is flexible along a length of the neck.
