A power meter for a bicycle includes a body having a torque input section and a torque output section, the body configured to transmit power between the torque input section and the torque output section. The power meter also includes a printed circuit board (“PCB”) having a substrate and at least one strain measurement device which may be attached to the PCB.

An actuator according to an embodiment includes a first rotating body that is rotatable around an input axis and includes a first groove part extending in a first direction, a second rotating body that is rotatable around an output axis and includes a second protruding part extending in a second direction substantially perpendicular to the first direction, a strain body that includes a first protruding part capable of being engaged with a first groove part through a gap whose direction is vertical to that of the input axis and a second groove part capable of being engaged with a second protruding part through a gap whose direction is vertical to that of the output axis and transmits a rotational torque of the input axis to the output axis, and a detection element that is attached to the strain body.

An elastic transmission element is used in a strain wave gear. Such strain wave gears are also referred to as Harmonic Drives. The elastic transmission element is also referred to as a flexspline. Outer toothing is formed on the elastic transmission element. Furthermore, at least one strain gauge for measuring a mechanical strain of the elastic transmission element is arranged on the elastic transmission element. The at least one strain gauge is formed as a coating directly on a metallic surface of the elastic transmission element.

A high torque active mechanism for an orthotic and/or prosthetic joint using a primary brake which can be provide by magnetorheological (MR) rotational damper incorporating and an additional friction brake mechanism driven by the braking force generated by the MR damper. This combination of MR damper and friction brake mechanism allows an increase in torque density while keeping the same level of motion control offered by the MR damper alone. The increased torque density achieved by this high torque active mechanism allows to minimize the size of the actuating system, i.e. its diameter and/or breath, while maximizing its braking torque capability. In this regard, the friction brake mechanism is advantageously positioned around the MR damper, such that the dimension of the package is minimized.

The pressure reading assembly further includes a sensing apparatus which includes a sensor disposed on a substrate and an engagement member including a generally columnar sealing member configured to engage an inner cylindrical surface of a receiving tube within the housing connected to the substrate about the sensor. The sealing member defines an axial bore extending from a proximal end to a distal end and includes an outer sealing surface defining one or more engaging elements configured to non-adhesively engage the inner cylindrical surface of the receiving tube to resist removal of the sensor assembly so that a pre-sterilized sensor assembly can be removed from a clean sealed packaging and joined directly with the housing.
