An Artificial Olfactory System Based on Synaptic Transistors for Precepting Hazardous Gas to Simulate Organ Injury

ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: May 14, 2025

Recent advances in artificial olfactory systems have attracted significant attention for their potential applications humanoid robots and intelligent nasal devices capable of identifying objects sensing hazards; however, the memory function is absent traditional gas sensors, which crucial to assess long-term exposure risks. Meanwhile, due high operation temperature requirement, sensors are usually difficult integrate with synaptic form systems. Here, we propose a novel device obtain memorize formaldehyde information. The composed an ion gel transistor integrated Ag-ZnO sensor, can simulate adverse effects human body make early warning. sensor detect recognize different concentrations as chemiresistive signal at room ultraviolet irradiation instead temperatures. formaldehyde-induced resistive changes transmitted gate voltage transistor, modulating channel conductance generate varying postsynaptic currents store information realize function. In addition, current data be imported into support vector machine (SVM) accurate identification, warning realized through system. This bionic system provides promising strategy development advanced intelligence danger warnings.

Study of MASnI3 perovskite photodetectors prepared by the inverse temperature crystallization method in ambient atmosphere and the spin coating method in a glovebox

Frontiers in Materials, Journal Year: 2025, Volume and Issue: 12

Published: May 20, 2025

In this study, we prepared MASnI 3 lead (Pb)-free halide perovskite metal-semiconductor-metal-type photodetectors through the inversion crystallization method under an atmospheric environment and spin-coating in a glove box, respectively. The scanning electron microscopy (SEM) images revealed different surface morphology. They show two types of growth models: inverse temperature (ITC) uses solvent volatilization, is reaction between precursors. For film obtained method, broad band photoluminescence (PL) spectrum at approximately 470 nm, corresponding to level transition 2.638 eV, was observed. On other hand, for narrow 773 1.604 This Burstein–Moss shift due introduction oxygen. addition, photocurrent device box orders magnitude higher than that by ITC method.
