Recent Progress of Halide Perovskites Applied to Five Senses Sensors

Abstract

The demand for sensors in various fields, such as medicine and materials, has increased. Owing to the recent development of flexible material technology, materials that can be attached to the body are also being developed. Five senses sensors that can replace the five senses of humans are worth investigating. Halide perovskite has excellent optoelectrical properties such as tunable bandgap, long carrier diffusion length, and high photoluminescence quantum yield. However, it has characteristics that are vulnerable to various external factors such as water, light, and gas. As a result, it is considered a material suitable for application to sensors. This study examines the research trends of halide perovskites to develop vision, olfactory, tactile, taste, and auditory sensors. Although studies have been conducted on the application of perovskite oxides in areas such as gas sensors, little research has been conducted in areas such as magnetic sensors. The feasibility of implementing the five senses sensor is addressed by conducting extensive research on these sensors.
