Abstract
A roll-to-roll printing process for large scale manufacturing of nanosensor systems for sensing pathophysiological signals is disclosed. The roll-to-roll manufacturing process may include three processes to improve the throughput and to reduce the cost in manufacturing: fabrication of textile based nanosensors, printing conductive tracks, and integration of electronics. The wireless nanosensor systems can be used in different monitoring applications. The fabric sheet printed and integrated with the customized components can be used in a variety of different applications. The electronics in the nanosensor systems connect to remote severs through adhoc networks or cloud networks with standard communication protocols or non-standard customized protocols for remote health monitoring.
