Highly integrated ultra-wide optical and acoustic sensory device: a honeybee-inspired approach for advanced robotic perception

Abstract

This study presents a highly integrated ultra-wide optical and acoustic sensory device inspired by the sensory systems of honeybees, including compound eyes and oscillatory dances. The device features a planar photonic synaptic array comprising an FA_xMA_1−xPbI₃ perovskite-based transistor (TFT) array and a PVDF–TrFE piezoelectric polymer membrane. The photonic synaptic array enables visible light detection with ultra-high resolution and a 180° field of view. The PVDF–TrFE film provides high acoustic sensitivity across a wide frequency range (1–13 000 Hz). This integration of optical and acoustic sensors facilitates advanced multidimensional perception, enabling precise motion detection and environmental responsiveness. The ultra-wide optical and acoustic performance demonstrates its potential for applications in advanced robotic perception, benefiting environmental adaptation and interaction.
