Printed Capacitive Pressure Sensor with Enhanced Sensitivity Through a Layered PDMS/BaTiO3 Structure

Sponsored by IEEE Sensors Council (https://ieee-sensors.org/) Title: Printed Capacitive Pressure Sensor with Enhanced Sensitivity Through a Layered PDMS/BaTiO3 Structure Author: Wenxin Wu, Kevin Schnittker, Joseph Andrews Affiliation: University of Wisconsin-Madison, United States Abstract: This paper presents a fully printed and soft capacitive tactile sensor system realized through a interdigitated capacitor and a cross-contacted patterned PDMS-BaTiO3 elastomer. The pressure signal translated into a perturbation of the fringing field, which responded by changing the capacitance. Tests using standardized pressure have been performed to measure and compare the sensitivity between pure PDMS and PDMS/BaTiO3 layered configuration. The capacitive response shows that the layered PDMS/BaTiO3 device enhances the sensitivity for pressures less than 1 kPa by approximately 10x. This work demonstrates the potential of a printed electronic sensor in measuring small-scale pressure variation using inexpensive and simple fabrication methods.
