This is a model.

In this field, it is the first to be able to Hold these situations at the same time. Besides, it allows you to experience it.

Their tests on the treadmill show that they wear this.

It can not only help people with walking disabilities, but also be used for special operators, and even for sports or entertainment. Imagine wearing it to make you run longer and walk more recklessly.

Did you suddenly have a bold idea?

From Harvard.

This study was conducted by a research team based at Harvard University. The whole equipment, shape is a shorts. It's not made of metal, it's made of textiles. Below the back, there is a mobile drive system controlled by an algorithm that can detect the transition from walking to running, and vice versa.

The device mainly assists the wearer through a cable drive system. When it works, the electric motor exerts tension between the waistband and the thigh through the cable, creating an external extension torque in the hip joint that works in coordination with the gluteal muscles.

Compared with other similar equipment using hard materials, this equipment is simpler in design and lighter in weight. The total number of components is 5 kilograms, but it is also equivalent to two bricks in the waist. More than 90% of the weight is close to the center of gravity of the body. The authors of the study say that this method of concentrating weight, combined with flexible fashion design, can minimize the burden on the wearer and movement restrictions.

The team said that they would then optimize all aspects of the equipment, including further weight loss, personalized assistance and improved ease of use.

Finally, let's get to know the author.

There are two authors, Philippe Malcolm and onor J. Walsh. Conor J. Walsh, a Harvard professor and founder of Harvard Biodesign Lab, is also the leader of the research team. Philippe Malcolm is an assistant professor at the University of Omaha, Nebraska.

There are also two first authors, Jinsoo Kim and Giuk Lee.

Jinsoo Kim is a PhD candidate in Engineering and Applied Science from Walsh's team. Giuk Lee, a former post-doctoral scholar of Walsh's team, is now an assistant professor at Central University in Seoul, South Korea. Walsh's team has been working in the field of exoskeleton equipment for a long time. The research on the cover of Science is the result of many years'technological optimization.

Earlier, they had worked with ReWalk Robotics to launch a device to improve the gait rehabilitation of stroke patients, which has been launched in the United States and Europe. They said a company would be set up in the future to commercialize the latest research.
