ABSTRACT

Nowadays, much of user interface is based on touch and the touch sensors have been common for displays, Internet of things (IoT) projects, or robotics. They can be found in lamps, touch screens of smartphones, or other wide arrays of applications as well. However, the conventional touch sensors, fabricated from rigid materials, are bulky, inflexible, hard, and hard-to-wear devices. The current IoT trend has made these touch sensors increasingly important when it added in the skin or clothing to affect different aspects of human life flexibly and comfortably. The paper provides an overview of the recent developments in this field. We discuss exciting advances in materials, fabrications, enhancements, and applications of flexible wearable sensors under view of touch-sensing. Therein, the review describes the theoretical principles of touch sensors, including resistive, capacitive, and piezoelectric types. Following that, the conventional and novel materials, as well as manufacturing technologies of flexible sensors are considered to. Especially, this review highlights the multidisciplinary approaches such as e-skins, e-textiles, e-healthcare, and e-control of flexible touch sensors. Finally, we summarize the challenges and opportunities that use is key to widespread development and adoption for future research.

摘要

如今，许多用户界面都基于触摸，并且触摸传感器已普遍用于显示器，物联网（IoT）项目或机器人技术。它们可以在灯，智能手机的触摸屏或其他广泛的应用程序中找到。然而，由刚性材料制成的常规触摸传感器是笨重的，不灵活的，坚硬的且难于佩戴的设备。当前的物联网趋势使这些触摸传感器添加到皮肤或衣服中以灵活，舒适地影响人类生活的各个方面，变得越来越重要。本文概述了该领域的最新发展。我们将在触摸感测的基础上讨论柔性可穿戴式传感器在材料，制造，增强和应用方面的令人激动的进展。其中，这篇评论描述了触摸传感器的理论原理，包括电阻，电容和压电类型。随后，考虑了传统和新颖的材料以及柔性传感器的制造技术。尤其是，本评论着重介绍了多学科方法，例如柔性触摸传感器的电子皮肤，电子纺织品，电子保健和电子控制。最后，我们总结了使用对未来研究的广泛开发和采用至关重要的挑战和机遇。
