Japan builds sixth finger robot

In fact, the sixth finger was created to study how the human brain responds to foreign body parts. There has been much research on the brain’s response to prosthetics, but in recent years scientists have begun to see potential in the field of body modification and experimenting with these Compact, stand-alone unit like a prosthetic finger. Since the human hand is already complete with five fingers, the scientists wanted to know if the brain could accept and master the new finger.

The sixth finger can move like a real finger

Besides serving the purpose of research, the sixth finger also supports people in many daily activities. In the video posted on Reuters, we can see that the sixth finger helps the wearer type faster, hold many objects in the hand at the same time …

To use the sixth finger, the experimenter will install sensors on the arm to measure the electronic signal. These signals are transmitted to the motor, allowing the wearer to control the sixth finger.

In an article on the official website of the University of Electronic Communication, the scientists asked: “Can the brain see an artificial, independent body part as part of itself? “. Through experiments with the sixth finger, they hypothesized that our brains can take control even with independent prosthetic limbs.

Professor Yoichi Miyawaki of the University of Electronic Communication said: “We know that we can use the brain to control the body, but when we add a new body part, can the brain adapt? We started this study because we were interested in whether the brain would accept the sixth finger or reject it…”. He believes that research on the sixth finger and artificial body parts will be the foundation for future humans to be able to freely “design” their bodies to their liking, blurring the boundaries between normal people. and disability.

Researchers in the UK have also studied the thumb independently of the human body

Previously, a research team from the University of London (UK) conducted a test of a thumb robot with a similar purpose. They fabricated the thumb using 3D printing method, which can be worn with a prosthetic finger next to the little finger of the hand. The wearer controls the thumb using pressure sensors mounted on the underside of the big toe. Professor Tamar Makin, from the University of London’s Institute of Neuroscience, said: “Body modification is a burgeoning field aimed at expanding our physical capabilities, but we don’t fully understand the set of brains yet. How will the brain adapt?
