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

Abstract

The increasing expense and complexity of conventional physical exams may lead to delayed disease diagnoses, creating substantial difficulties for many patients. In response, smartphone-based sensing technologies have emerged, offering a promising solution to make health diagnostics more accessible. Perovskite-based nanomaterials stand out with their adaptable structure, making them an important player in sensor enhancement due to their wide-ranging sensing capabilities and excellent physicochemical characteristics. While perovskites demonstrate advantageous optoelectronic properties, fortifying their stability is a crucial aspect that continues to be a central theme in current research and development endeavors. This article examines the advancement of smartphone-based sensors via the incorporation of Perovskite-based nanomaterials and suggests strategies for further optimizing their characteristics. It provides a detailed overview of their applications in different smartphone sensing areas, including but not limited to optical and photothermal-pyroelectric methods. Our in-depth analysis highlights the crucial role of Perovskite-based nanomaterials in the development of devices and the complexity of sensor manufacturing. We also explore their potential in seamlessly integrating with wearable devices connected to smartphones, thus streamlining the diagnosis process. Moreover, we anticipate their revolutionary impact in advancing smartphone sensors. This combination is poised to establish a more accessible and unified method for health monitoring.
