Application and analysis of contemporary flexible tactile sensors

Abstract

In order to meet the increasing demand for electronic products in contemporary society, relevant manufacturers have been continuously improving related technologies. While electronic products are convenient, they are plagued by issues such as rapid power consumption, susceptibility to damage, and inconvenience in portability. Therefore, many countries have developed foldable screen smartphones, computers, and other electronic products. In China, major brands such as OPPO and Huawei have released foldable screen smartphones, effectively addressing issues like portability. In this article, a background study of flexible tactile sensors is first conducted to ensure a thorough understanding of their applications. Secondly, based on the working principle of flexible tactile sensors and their different categories, the current research status is analyzed. The classification can be further refined according to the information transmission mechanism and application scenarios. In the former classification, detailed principal introductions are provided for each type of sensor. In the latter classification, based on the existing environment, detailed analyses of the production methods and characteristics are carried out in multiple fields such as tablets and smartphones, laying the groundwork for subsequent discussions. Furthermore, from the perspectives of preparation, characteristics, and power supply, I identify the existing problems and shortcomings that need improvement today, providing detailed explanations. Finally, relevant solutions are proposed for the aforementioned issues, and prospects for the extensive application and bright future of flexible tactile sensors are discussed, including in the fields of biointerfaces, cellular domains, and future mechanical domains.
