Abstract
A flexural actuator is fitted with an actuator means, the flexural actuator being fitted at its functional section with a sensor means for determination of the longitudinal stretch. This sensor means is placed at a position, and/or is placed in the longitudinal direction symmetrically on either side of such position, at which there is a constant longitudinal stretch independent from the setting force when the functional section is thrusting against a resistance.
Claims18
A flexural actuator having an elongated shape, comprising an attachment section for fixation of the flexural actuator and a functional section, extending away from the attachment section, able to be deflected athwart the longitudinal axis thereof by activation of the flexural actuator, such functional section being provided with at least one sensor means suitable for detecting longitudinal stretch, wherein the sensor means is placed at a position, and/or symmetrically on either side of such position, at which, when the functional section thrusts against a resistance there is a constant longitudinal stretch independent of the setting force.
An actuator means, comprising a flexural actuator which is fixed in place by means of an attachment section on a base, and which comprises a functional section extending away from the attachment section, which functional section is able to be deflected by activation of the flexural actuator athwart the longitudinal axis thereof and may be thrust against a resistance arranged in the deflection path and which is provided with at least one sensor means responsive to the longitudinal stretch, wherein the sensor means is placed at, and/or in the longitudinal direction on either side, of a position, at which with the functional section thrust against the resistance, there is a constant longitudinal stretch independent of the setting force.
