Abstract: An object of this invention is to detect an external force or acceleration with good sensitivity using a simple configuration. An external force detection sensor comprises a comb electrode including a fixed electrode having a plurality of fixed combtooth portions and a movable electrode having a plurality of movable combtooth portions inserted between the fixed combtooth portions; a power supply connected to the fixed electrode and the movable electrode in order to cause vibration of the movable electrode at a prescribed resonance frequency through an electrostatic force on the fixed electrode; and detection means for detecting an external force based on a change in electrical characteristics between the fixed electrode and the movable electrode when the movable electrode is caused to vibrate. With respect to the fixed combtooth portions that are adjacent to each other and the movable combtooth portion inserted therebetween, the spacing between one of the fixed combtooth portions and the movable combtooth portion is different from the spacing between another of the fixed combtooth portions and the movable combtooth portion.

Abstract: An electromechanical force transducer comprises at least two adjacent resonant elements and a damping layer coupled between their adjacent faces. The damping layer is selected so that the output is increased in the region of internal cancellation in the transducer. The adjacent resonant elements are beam-like and have substantially the same length. The resonant elements may be supported on a stub of low rotational stiffness whereby the fundamental resonance of the transducer becomes less dependent on bending motion of the transducer and more rigid body-like. The transducer may also include a member for increasing the rotational impedance of the transducer.

Abstract: A high frequency flexure-based dynamometer (10) for measuring vibrations to use in determining cutting forces in a tool. The dynamometer device (10) may operate within a preselected high frequency range while measuring cutting forces less than about 1 N. The dynamometer (10) may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant. The dynamometer (10) may include a workpiece (38) mounted to one of the two flexures (12) and a one or more precision accelerometers (30) mounted to the first or second flexures. Finite element analysis may be used to optimize the flexure design.
