Printed Electronics Applications: Sensors, Actuators and Biosensors

The thin, flexible and lightweight features of printed sensors and other electronic devices suggest that the development and utilization of printed electronics technology in flexible/wearable electronics and biomedical applications have reached maturity, and yet the actualization of this technology is not straightforward. Research in this field is growing very quickly, attributed to the success and combined efforts of the multidisciplinary printing engineering, materials science, biotechnology and electronics communities. In this chapter, the mechanism, fabrication methods and recent progress of printed physical sensing devices (PPSDs), printed electrochemical sensing devices (PESDs), printed actuators and printed biosensors are systematically demonstrated.
