**"The human body changes shape, but prosthetic sockets don't."**Our bodies are approximately 1.5 cm shorter in the evening, compared to the morning. Our feet and hands are larger in evenings. Most of us don't notice these changes because we wear flexible clothes.However, if you lose a leg, you must wear a prosthetic limb attached to your body with a rigid U-shaped structure called a _socket_. Sockets are made of hard plastics to carry the bodyweight and hand-made to ensure the best custom-fit by following the stump's contour. Sadly, 75% of amputees are unhappy because the stump changes shape on an hourly basis whilst their custom-made rigid sockets don't. This leads to constant skin-rubbing, causing painful bleeding wounds and ulcers. Replacing sockets up to 4 times annually for the rest of amputees' lives is currently the best solution, costing £7.1billion public money in the UK, EU and US each year (Excluding woundcare cost: £2.4billion in UK alone(UK-Government/APPG;2019)).**What:** Roliner is a sleeve-like device worn on the stump before wearing the prosthetic leg.**How:** Roliner uses Artificial Intelligence to understand hourly/daily changes in the stump and adapts to them. Roliner's AI reads real-time sensors' data between the stump and socket, learns amputees' comfort preferences via an app, and seamlessly and continuously adjust the fitting by inflating/deflating Roliner's micro-channels.**Impact:** Prosthesis fitting is the biggest barrier for amputees to maintain daily activities. Amputees depend upon fitting clinics. Therefore, within the first year of amputation, 1-in-6 amputees lose their jobs. 44.3% working-age amputees are economically inactive, costing £4.89billion in productivity loss(PapworthTrust,2016). Roliner's AI mimicking clinical practice will provide able-bodied-like walking experience, increase walking performance x3 times, reduce hospital dependency, and potentially save the NHS £1billion in socket adjustments, £2.4billion in socket wounds.This project advances us from prototype to a clinical-testing device.

**“人体的形状会改变，但假肢接受腔不会。”**与早上相比，我们的身体在晚上大约会变短 1.5 厘米 我们大多数人的脚和手在晚上都不会变大。请注意这些变化，因为我们穿着灵活的衣服。但是，如果您失去了一条腿，则必须佩戴带有刚性 U 形结构（称为“插座”）的假肢，以承受体重和重量。遗憾的是，75% 的截肢者不满意，因为残肢每小时都会改变形状，而定制的刚性承窝则不会。目前最好的解决方案是在截肢者的余生中每年更换多达 4 次关节窝，这会导致伤口疼痛流血和溃疡，在英国、欧盟和美国每年要花费 71 亿英镑的公共资金。 （不包括伤口护理费用：仅在英国就花费了 24 亿英镑（英国政府/APPG；2019 年））。**内容：** Roliner 是一种袖状装置，在佩戴假肢之前戴在残肢上。**如何：* * Roliner 使用人工智能来了解残肢每小时/每天的变化并进行适应 Roliner 的人工智能读取残肢和接受腔之间的实时传感器数据，了解截肢者的舒适度。通过应用程序进行偏好设置，并通过对 Roliner 的微通道进行充气/放气来无缝、连续地调整配件。 **影响：** 假肢配件是截肢者维持日常活动的最大障碍，因此，在截肢诊所内。截肢第一年，六分之一的截肢者失去了工作 44.3% 的工作年龄截肢者没有经济活动，生产力损失了 48.9 亿英镑。 （PapworthTrust，2016）Roliner 的人工智能模仿临床实践将提供类似健全人的步行体验，将步行性能提高 3 倍，减少对医院的依赖，并可能为 NHS 节省 10 亿英镑的插座调整费用和 24 亿英镑的插座伤口费用。该项目将我们从原型推进到临床测试设备。
