The worldwide medical device market is over $300 billion annually, but there is increasing pressure from governments, insurers, and patients to bring down healthcare costs. Printed, flexible, and organic electronics have the opportunity to lower costs while also improving the overall quality of care and generating substantial markets. A winning device requires the right combination of sensor, treatment, and/ or electrode technologies and the right market fit. However, many of these technologies have been overhyped, and sorting out real potential is critical. We assess emerging sensor, treatment, and electrode technologies across eight markets to uncover substantial business opportunities for printed, flexible, and organic electronics in healthcare.
