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.

Unlocking the potential of perovskite-based nanomaterials for revolutionary smartphone-based sensor applications

“…Additionally, the lattice structure is notably malleable, allowing for intricate material-level engineering. [58][59][60] This also affords the creation of highly specific binding sites for targeted analytes, achieving a level of specificity that transcends traditional surface-level modifications. [61][62][63][64] Furthermore, the synthesis of perovskite-based nanomaterials is both scalable and economically viable, rendering them an attractive proposition for the mass production of sophisticated biosensors.…”

Thermal degradation in methylammonium–formamidinium–guanidinium lead iodide perovskites

“…Halide perovskites have the general chemical formula of the type ABX 3 , where A denotes a monovalent cation, B a divalent cation, and X a halide anion composed of a tridimensional arrangement of corner-sharing PbX 6 octahedra, and have found many applications in optoelectronic and electrochemical devices, including solar cells, LEDs, lasers, X-ray and nuclear radiation detectors, sensing, photocatalysis, and organic synthesis. [1][2][3][4][5][6][7][8][9] Despite the unprecedented success in inexpensive laboratory applications, the low stability of halide perovskite materials and devices is one of the main bottlenecks for their definitive commercial usage. [10][11][12] Among the possible degradation stressors are humidity, oxygen, light, high temperatures and thermal stresses, bias voltages, and interfacial reactions between layers in perovskite devices.…”
