Advances in virtual health monitoring, robotics, internet of things (IoT), and other emerging applications drive the technological improvements in flexible electronics and smart materials capable of sensing and energy harvesting. Lead-free piezoelectric polymer composites will be the materials of choice in these emerging applications due to their improved performance, non-toxic components, mechanical flexibility, light weight, processibility, and ease of integration into devices. Additionally these materials provide the potential to be self-powered, which might reduce or eliminate the need for batteries in certain devices.In this article, researchers from SABIC, a leading global chemical company and material solution provider, present an overview of their novel, high performing piezoelectric polymer composites developed using elastomeric polymers in combination with lead-free piezo ceramic additives. These novel composites show improved force sensitivity and temperature stability when compared to commercially available piezoelectric polymers. These property improvements open up new application spaces for flexible piezoelectric devices such as smart gloves, shoes, health monitoring patch, key pads, and haptic feedback.
