摘要：
对跌倒及潜在受伤的担忧，使许多老年人无法参与步行、舞蹈、太极等有益健康的运动。现有被动式装置如助行器需要用手臂支撑，而主动式装置如外骨骼和机器人框架通常刚性、笨重且易带来污名，限制了其应用。FallGown是一种软质可穿戴支撑结构，由织物外壳内的加压气动囊组成，可支撑使用者的全部体重，旨在预防跌倒。它具备便携性（收纳后重6.9千克，体积0.051立方米）、负担小（根据地面类型及是否使用可选的滚动底座框架，拖拽力为7.24至20.8牛）、穿戴便捷（平均穿戴时间不足2.5分钟，脱卸时间不足0.5分钟）。可选的滚动底座可降低与地面的摩擦力，但会降低便携性并减小裙部变形（裙部变形有助于通过门等狭窄空间）。对单名使用者的防跌倒测试显示，装置尺寸与抗倾覆稳定性之间存在权衡；配备12个气动囊、地面直径1.4米且带有底座框架的裙部，除一次机械故障导致的情况外，可预防所有跌倒。机载压力传感器可感知使用者的体重分布，为受监测的运动和自适应支撑提供可能。
英文摘要：
Concerns about falling and potential resulting injuries prevent many older adults from participating in forms of health-improving exercise such as walking, dance, and tai chi. Existing passive devices like walkers require use of the arms for support, and active devices like exoskeletons and robotic frames are often rigid, bulky, and stigmatized, which limits their use. The FallGown is a soft wearable support structure consisting of pressurized pneumatic pouches within a fabric shell; it can support the full weight of a user's body and aims to prevent falls. It is portable (6.9 kg and 0.051 m3 when stored), minimally burdensome (7.24-20.8 N drag force depending on floor type and whether an optional rolling base frame is used), and convenient (less than 2.5 minutes on average to don and less than 0.5 minutes on average to doff). The optional rolling base lowers friction with the floor, but reduces portability and skirt deformation (which can be useful to fit through doors and other tight spaces). Fall prevention testing with a single user revealed a tradeoff between device size and stability against tipping; a skirt with 12 pneumatic pouches and a floor diameter of 1.4 meters with a base frame prevented all falls except in one case with a mechanical failure. On-board pressure sensors can sense the user's weight distribution, providing an opportunity for monitored exercise and adaptive support.
