Implanted in freely moving subjects, new rechargeable wireless brain sensors can relay real-time broadband signals from up to 100 neurons, report neuroengineers. Several copies of the novel low-power device, described in the Journal of Neural Engineering, have been performing well in animal models for more than year, a first in the brain-computer interface field. Brain-computer interfaces could help people with severe paralysis control devices with their thoughts.
