Researchers at the Korea Advanced Institute of Science and Technology have found how to charge the device, which was reportedly the size of a grain of salt, from outside the body.
According to the British newspaper “Daily Star”, these Bluetooth-enabled chips use light to send messages to nerve cells in the brain.
Scientists believe these chips could be used later in treating Parkinson’s disease and depression.
The research team said that they were able to manipulate and influence the brain in mice injected with cocaine, where they succeeded in stopping the behaviors caused by cocaine.
It is very exciting to control certain animal behavior by using light stimulation in the brain via a smartphone application, said Jung Hun Kim, a brain specialist at Yonsei University, noting that this technology will facilitate different methods of brain research.
The device is installed in the brain with LED lights installed on sensors the width of a human hair, and it is controlled wirelessly by a smartphone, but scientists have modified the system, as the new version includes a wireless power machine with an antenna that captures alternating magnetic fields and generates electricity.
Professor Jae Wong Jeong, who led the research, said: “We believe the same basic technology can be applied to different types of implants, including deep brain stimuli, pacemakers and stomach devices for long-term use within the body.”
