Tiny wireless sensor moves brain research forward

Researchers at the Rehabilitation Engineering Program of the National Institute of Biomedical Imaging and Bioengineering (NIBIB), part of NIH, have been testing a compact, self-contained sensor that has been used to record and transmit brain activity data for more than a year in animal studies. So far, scientists have tested the implantable device in pigs and rhesus macaques, finding that the sensors could transmit signals more than three feet away without degrading in quality over the time span of the study. Scientists say the technology has the potential to open up new rehabilitation options for patients. The research is a step toward cord-free control of prosthetics that eventually could be brain-controlled, they say. Story | Abstract
