外骨骼是贴身设备，穿戴时不会像刚性设备那样限制用户的运动。这些软装置通过使用灵活的跨关节线性元件来增强下肢生物力学，这些元件被驱动以在跨关节周围产生力矩，有效地利用人体作为从输入到输出的机械传输。因此，外装套装对给定关节产生的力臂的大小取决于用户的体型和形状，以及取决于他们正在谈判的地形的个性化步态模式。这些高度可变的人类和环境因素会影响所有软外装（被动和主动）的性能，量化这些影响的能力将有利于辅助设备的开发。在这项工作中，我们提出了一个系统，用于模拟用户体重指数、生物性别和步态运动学对任务依赖性外装性能的影响。我们使用该系统来评估髋屈外装在从 3D 人体表面模型数据库获得的一系列体形上的性能，以及来自物理实验的步态运动学。我们的结果表明，用户的体重指数、性别和步态运动学是设计个性化辅助外衣时需要考虑的必要因素。这种类型的分析可以让设备开发人员在生成新设计、开发在线控制算法或为特定个体配置设备时考虑个体的独特形状和步态模式。
Exosuits are close-fitting devices, which are meant to be worn without restricting the motion of the user in the way that a rigid device would. These soft devices augment lower-limb biomechanics by using flexible, joint-spanning linear elements that are actuated to create moments about the spanned joints, effectively using the human body as the mechanical transmission from input to output. Consequently, the size of the moment arm that an exosuit creates about a given joint is dependent on the size and shape of the user, as well as their individualized gait patterns that depend on the terrain they are negotiating. These highly-variable human and environmental factors affect the performance of all soft exosuits (both passive and active), and the ability to quantify these effects would benefit assistive device development. In this work, we present a system for modeling the effects of user body mass index, biological sex, and gait kinematics on task-dependent exosuit performance. We use this system to estimate the performance of a hip-flexion exosuit over a range of body shapes obtained from a database of 3D human surface models, and with gait kinematics from physical experiments. Our results demonstrate that the user's body mass index, sex, and gait kinematics are necessary factors to consider when designing an exosuit for personalized assistance. This type of analysis can allow device developers to account for the unique shape and gait patterns of individuals, either in generating new designs, developing online control algorithms, or in configuring devices for specific individuals.
