Electrical muscle stimulation will give humans superhuman reflexes

Robots have a reaction that far exceeds that of a human. It's not just ultra-fast drives, but also sensory and control systems that surpass our brains and nervous systems in their capabilities. But this can be changed by entrusting control of our muscles to robots and making them move faster using the electrical stimulation system (EMS).

Researchers at Sony and the University of Chicago are currently working together to develop just such an EMS to speed up our reflexes. The average response time of a healthy person is about 250 ms, that is, about a quarter of a second. Of these, "awareness of intention" takes about 200 ms, and the remaining 50 - to set in motion the desired muscle group. The researchers suggest that this 50 millisecond interval can be shortened, which will give the person the ability to react more quickly to a specific situation.

The main disadvantage of this method: it only works if the person's goal matches the goal of the electronic system. In this case, the complex will work perfectly. But if suddenly a person changes his mind in the last millisecond to act, his muscles will contract anyway.

Research results can be useful for organizing human interaction with robotic systems. In the near future, exoskeletons will replace wheelchairs as a means of transportation, and millions of disabled people will gain control over their bodies.
