近几年来，科学技术在不可思议地进步着，但是，大多数情况下，它似乎只能使少部分富足的人群受益。工程师克里丝塔· 唐纳森为我们介绍了“移动假膝”，一种为膝上截肢者设计的假肢，而这些截肢者中的很多人每天的生活费不足四美元。这种产品不但拥有一流的品质，也比市面上的其他假肢要便宜得多。

改变人一生的80美元假膝

Millions of amputees in low-income countries face a harsh choice between costly prosthetics and makeshift aids like bamboo staffs. A breakthrough $80 polycentric knee offers mobility and dignity previously reserved for the wealthy. The design matches high-end performance but is tailored for local needs, from sitting cross-legged to withstanding rugged use. This approach reimagines how advanced technology can reach everyone, not just the fortunate few.
