The device read the brain waves accurately, safely

A team of scientists from the University of Tokyo and Niigata University in Japan have successfully researched new brain signaling devices.

This device can accurately detect brain waves without hurting the surrounding organization.

Earlier, the method of reading the signal by implanting the electrode into the brain was done, however, the electrode's function could not be maintained, further damaging the surrounding organ.

Or, as the brainwave-checking device is installed on the outside, though it does not hurt the body, but because the electrode-fixing material is silicone, it can not be tightly coupled to the head. Moreover, the distance between the electrodes is just 1cm, so the sensitivity is very low.

The new device, which is used by PC scientists for its flexibility, is free to change its shape and tightly integrate it with the head, so that sensitivity is similar to the sensitivity of the implant. pole into the brain.

First, the scientists work on polymer PC materials to make the surface of which is deposited by needle-holes, then further processed by microelectronic mechanical systems. 0.5mm to 1mm on the surface of the PC material for the installation of a small electrode.

During the experiments on the monkeys, scientists placed 128 electrodes on PC material of 3cm in length and 5cm in width to make the sensitivity of the device fully meet the expected effect.

This new technology contributes greatly to the lives of patients with spinal cord injuries.
