Mechanical concepts and designs in inorganic circuits for different levels of stretchability are reviewed in this paper, through discussions of the underlying mechanics and material theories, fabrication procedures for the constituent microscale/nanoscale devices, and experimental characterization. All of the designs reported here adopt heterogeneous structures of rigid and brittle inorganic materials on soft and elastic elastomeric substrates, with mechanical design layouts that isolate large deformations to the elastomer, thereby avoiding potentially destructive plastic strains in the brittle materials. The overall stiffnesses of the electronics, their stretchability, and curvilinear shapes can be designed to match the mechanical properties of biological tissues. The result is a class of soft stretchable electronic systems that are compatible with traditional high-performance inorganic semiconductor technologies. These systems afford promising options for applications in portable biomedical and health-monitoring devices. Mechanics theories and modeling play a key role in understanding the underlining physics and optimization of these systems.

软电子中无机可拉伸电路的机械设计

本文通过讨论基本的力学和材料理论，组成微型/纳米级器件的制造程序以及实验特性，对无机电路中不同程度的可拉伸性的机械概念和设计进行了综述。此处报道的所有设计均在柔软和弹性的弹性体基材上采用刚性和脆性无机材料的异质结构，其机械设计布局可将弹性体的大变形隔离开，从而避免了脆性材料中潜在的破坏性塑性应变。电子设备的整体刚度，可拉伸性和曲线形状可以设计为与生物组织的机械性能相匹配。结果是与传统的高性能无机半导体技术兼容的一类软可拉伸电子系统。这些系统为便携式生物医学和健康监测设备中的应用提供了有希望的选择。力学理论和建模在理解这些系统的基础物理和优化方面起着关键作用。
