    Abstract: A bistable structure provided by the invention is characterized as including a deflection element that has mechanically constrained end points and a compliant span between the end points that is substantially free to deflect between two stable positions when a force is applied at a point along the span. The deflection element span is provided, as-fabricated, curved in one of the two stable positions and in a mechanically unstressed condition along the length of the span. The as-fabricated curve of the deflection element span includes a curve maxima at a point along the span length that is at least about 1/4 of the span length from the end points of the span. The deflection element span is constrained to substantially prohibit development of a second bending mode that is characteristic for the span as the element deflects between the stable positions.

    Abstract translation: 由本发明提供的双稳态结构的特征在于包括一个偏转元件，该偏转元件具有机械约束的端点和端点之间的顺应跨度，当在沿跨度的点施加力时，基本上自由地在两个稳定位置之间偏转。 偏转元件跨度设置成沿着跨度的长度在两个稳定位置中的一个中以及在机械上不受应力的条件下被弯曲。 偏转元件跨度的制造曲线包括沿着跨度长度的点处的曲线最大值，该曲线最大值距离跨度的端点的跨度长度的至少约1/4。 偏转元件跨度被限制为基本上禁止当元件在稳定位置之间偏转时跨度的特征的第二弯曲模式的发展。

    Abstract: An instrument for enabling a precise determination of the force-displacement characteristics of a compliant structure, including both in-plane and out-of-plane structure deflection, is provided by the invention. The instrument includes a fixture that is oriented for constraining an end of the compliant structure with respect to mechanical ground as the force-displacement characteristic is determined. A mechanical probe of the instrument is disposed relative to the fixture to enable pushing of the probe against a free end of the compliant structure. A mechanical stage is provided, including a support for the probe, and being free with respect to mechanical ground to advance the probe relative to the fixture. This enables pushing of the probe against the free end of the compliant structure. A reference element is connected to the stage, and a displacement transmission element is disposed relative to the mechanical probe and the compliant reference element to transmit deflection of the compliant structure, produced by pushing of the probe, to the compliant reference element. A displacement sensor is disposed relative to the displacement transmission element to measure displacement of the transmission element, and a displacement sensor is disposed relative to the mechanical stage to measure displacement of the mechanical stage. The compliant reference element and the displacement transmission element can be configured with respect to the constraining fixture to accommodate deflection of the compliant structure along more than one axis, e.g., along either of two deflection axes.
