This paper-thin sensor developed at Northwestern University, includes 396 voltage sensors that can attach to the outside of the heart. It relies heavily on capacitive coupling that reads signals from the heart.
“You want this layer to be as thin as possible to enable a strong electrical coupling to the surrounding tissue, but you need it to be thick enough to serve as a robust barrier to water penetration,” says John Rogers, professor at Northwestern University.
The sensor is designed with silicon dioxide glass, allowing it to be strong while being thin.
