Upgrade to Superhuman Reflexes Without Feeling Like a Robot

Electrical muscle stimulation can speed up human reflexes. But can we use it without giving up control of our bodies?

We’re used to seeing robots with reflexes that are much faster than anything humans are capable of, but it’s not just high-speed actuators that make them so quick. Perception and control systems outperform our own nervous systems and brains, meaning that we can boost our own reaction times by just letting a robot take control of our muscles. It’s not very hard to do this—all it takes is electrical muscle stimulation (EMS), which uses electrode pads attached to the skin to gently shock your muscles, causing them to contract.

By adding sensors to an EMS system, physical reaction times can be significantly reduced, since the EMS is able to actuate your muscles much faster than your brain can. Essentially, you’d be a puppet, having surrendered your free will to a computer that can force you to move. This may not be a trade-off that you want to accept, which is why researchers from Sony and the University of Chicago are working on an EMS system that makes your reflexes noticeably faster without completely removing the feeling that you’re doing things yourself.
