As people strive ever harder to minutely quantify every action they do, the sensors that monitor those actions are growing lighter and less invasive. Two prototype sensors from crosstown rivals ...

A thin film that combines an electrode grid and LEDs can both track and produce a visual representation of the brain's activity in real-time during surgery -- a huge improvement over the current state ...

Engineering researchers have invented an advanced brain-computer interface with a flexible and moldable backing and penetrating microneedles. Adding a flexible backing to this kind of brain-computer ...
