This paper presents a new automatic optimal design formulation to achieve high sensitivities of the strain-gauge-based force sensors based on the method of moving morphable units (components or voids). We examine our design formulation through several examples, of which the results demonstrate the feasibility and efficiency of the proposed approach. In addition to the explicit boundaries that are finally derived, the current formulation has another superiority that the strain gauge locations can be easily treated as design variables by taking the sensing areas as additional components. Furthermore, the formulation is compatible with the shape optimization such that we can unite topology design and shape design of force sensors into one optimization framework.

本文提出了一种新的自动优化设计公式，该公式基于移动可变形单元（组件或空隙）的方法来实现基于应变计的力传感器的高灵敏度。我们通过几个示例检查了我们的设计公式，其中的结果证明了所提出方法的可行性和效率。除了最终得出的明确边界外，当前公式还具有另一个优势，即通过将传感区域作为附加组件，可以轻松地将应变仪位置视为设计变量。此外，该公式与形状优化兼容，因此我们可以将力传感器的拓扑设计和形状设计整合到一个优化框架中。
