That’s why John Rogers , professor of materials science and engineering at Northwestern University, collaborated with a team of researchers to develop a new type of sensor that is much safer, more refined, and could likely survive in the body about 70 years. These paper-thin devices are an array of 396 voltage sensors set in 9.5 x 11.5 mm multi-layer flexible substrate that’s meant to attach to the outside of the heart, covering a significant portion of the organ.
