Publisher's Version Abstract
Technological advancements drive demand for smart, flexible, and sustainable devices capable of integration into daily life. Pressure sensors, particularly those utilizing halide perovskites, face key challenges in sensitivity, stability, and integration with soft systems. This study focuses on the investigation of quasi two-dimensional (2D) perovskite pressure sensors, where the perovskite is embedded within a Polyvinylidene fluoride (PVDF) polymer matrix, and protected by Polydimethylsiloxane (PDMS) polymer layer. The improvement in the performance of the pressure sensors is achieved through the optimization of solvent composition, perovskite:PVDF ratio, and the thickness of the PDMS layer, with a deep understanding of the morphological structure's influence on piezoelectric properties. Our perovskite layer achieves a high piezoelectric coefficient (d33) of 31.26 pm/V, surpassing previously reported values for halide perovskites. Unlike previous studies, we systematically investigate the correlation between PDMS thickness and piezoelectric response, identifying a critical thickness threshold (~23 μm) beyond which sensing is suppressed. The devices demonstrate pressure sensitivity in the absence of any external power source and maintaining reliable performance for 1,000 cycles and up to 60 days in ambient conditions. Successful integration of the sensors into soft robotic gripper while also demonstrating sensitivity to various weights highlights their potential for applications in fields such as soft robotics, and healthcare.
