Roll-To-Roll Printing of Wearable Sensors and Devices for Personalized Health Monitoring |Biomedgrid

Personalized Health Monitoring (PHM) is a growing field in the medical community that is intended to address the needs of patients requiring regular monitoring of biodata from a distance. Successful efforts have been made in recent years to solve this problem using wearable electronic sensors/devices. The most effective designs utilize flexible electronics: sensor arrays mounted on polymer substrates that can be wrapped on the skin. While immensely useful due to their inherent advantages in conformability, comfort, and lightweight structures, the challenge lies in finding effective ways to manufacture these devices on a mass scale. Roll-to-Roll (R2R) printing promises high-throughput, high-fidelity fabrication via multiple different methods of imprinting conductive patterns on the substrate. This review examines the applications of these different methods and some of the results that have been demonstrated thus far.
