Development of a dual-layer structured piezoelectric film for haptic applications

Abstract
Haptic technology improves digital interactions by simulating the sense of touch through tactile feedback or vibrations, creating more natural and responsive experiences. However, developing soft piezoelectric actuators for haptic feedback poses challenges, particularly in balancing mechanical flexibility with strong piezoelectric properties. This study addresses these issues by introducing a dual-layer flexible film made of polyvinylidene fluoride-co-trifluoroethylene (P(VDF-TrFE)) and barium titanate (BaTiO3, BTO). Scanning electron microscope (SEM) observation, alongside tests on piezoelectric properties, and electric field response, demonstrated that the dual-layer design outperforms traditional piezoelectric films, especially in the 31-direction commonly used in haptic systems. This approach provides a promising solution to enhance the efficiency and flexibility of piezoelectric actuators in haptic technology, opening up possibilities for improved haptic devices.
