F8BT-based highly sensitive humidity sensor for metaverse interfacing

Abstract

The fourth industrial revolution requires sensor-based space interfacing technologies between the real world and the metaverse. This technology demands prompt responsiveness and significant computational resources. Specifically, the sensor is playing a crucial role to develop for internet of Things (IoT) technologies for metaverse interfacing. This paper proposes a metaverse interfaceable applied Poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt-(benzo [2,1,3] thiadiazol-4,8-diyl)] (F8BT) based humidity sensor showing linear capacitance and impedance behavior having a good response (4 s) and recovery time (6 s). Moreover, the fabricated sensor is employed for determining mouth breathing application. In addition, we also investigated the moisturized finger from various distances and defined the distance-related study using a support vector machine (SVM). At different humidity levels, a change in light is observed in the modeled metaverse platform as a digital twin application by the Unreal engine. We are sure that the proposed humidity sensing device interconnecting with the IoT technology will pave a new path to investigate environmental predictions.
