Superhero-style undersuit relieves back pain
    2017-September-18  08:53    Shenzhen Daily

Inventors have developed briefs that contain wearable technology designed to get rid of pain in the lower back. Experts said many potential solutions for back pain are unproven, unworkable or just unattractive.

Now a team of engineers from Vanderbilt University in Tennessee, the United States hope to change that with a design that combines the science of biomechanics and advances in wearable technology to create a smart, mechanized undergarment.

Lead researcher Karl Zelik, an assistant professor of mechanical engineering, started exploring wearable technology solutions after suffering back pain himself from repeatedly lifting his young son.

Tests so far show that the smart clothing relieves stress on the lower back.

The device consists of two fabric sections made of nylon canvas, Lycra, polyester and other materials, for the chest and legs.

The sections are connected by sturdy straps across the middle back, with natural rubber pieces at the lower back.

The device can be controlled by an app the team created — users tap their phones to engage the smart clothing wirelessly via Bluetooth. It can also be controlled by a light tap to the chest.

It is designed so that users engage it only when they need it. The user just double taps their shirt, or their smart phone, to engage the straps.

When it is turned on, the elastic straps tighten so when the user completes a task, like lifting a heavy object, some of the pressure is diverted from the lower back to the straps.

And when the task is done, another double tap releases the straps so the user can sit down, and the device feels and behaves like normal clothes.

Eight subjects tested the device leaning forward and lifting 25-pound (about 11.3 kilograms) and 55-pound weights while holding their position at 30, 60 and 90 degrees.

Using motion capture, force plates and electromyography, which records the electric activity of muscle tissue, the team showed the device reduced activity in the lower back muscles by an average of 15 to 45 percent for each task.

发明者已经研制出了一种内裤,该内裤运用了可以消除腰部疼痛的可穿戴技术。专家称,很多可能消除背痛的办法都是未经检验、不可行或者不美观的。

现在美国田纳西州范德堡大学的一个工程师团队有望通过将生物力学与先进的可穿戴技术结合起来,制造一件智能的,机械化的内衣来解决腰痛的问题。

首席研究员卡尔•泽里克是机械工程学的一名助理教授,他因为经常抱举年幼的儿子而感到腰痛,这之后他就开始探索运用可穿戴技术解决这一问题。

目前的测试表明该智能内衣减轻了腰部所受压力。

该装置由分别穿戴在胸部和腿部的两部分织物组成,每一部分由尼龙帆布、莱卡、聚酯等材料制成。

这两部分由穿过后背中部的结实带子和腰部的天然橡胶片连接。

该团队研发的应用可以控制这套装备。用户可以通过蓝牙无线操作,轻触手机就能使智能内衣上下接合。用户还可通过轻触胸部织物进行操控。

这样的设计可以让用户根据自己的需求连接设备。用户只要轻触两下上衣或智能手机就能将带子连在一起。

当装置启动时,弹力带就会收紧,因此当用户完成任务的时候,比如举起重物,腰部所受的力就会部分转移到带子上。

当任务完成后,再轻拍两下,带子就会松开,这时用户就可以坐下,智能内衣也就和一般的衣服没什么两样了。

八位试验者保持在弯腰30度、60度和90度时举起25磅(约合11.3公斤)和55磅的重物,来测试该装置。

研究团队用运动捕捉、测力板和肌电图来记录肌肉组织的电活动,结果显示,在每一项任务中,智能内衣把腰部肌肉活动平均减少了15%至45%。(Chinadaily.com.cn)
