柔性电子技术极大地改变了传感器的能力，使我们不仅可以检测皮肤上的人体生物信号，还可以检测人体内部的信号。粘附在皮肤表面的可穿戴传感器可以检测各种生物力学运动，生物信号和副产品，例如来自汗液和体温的有用元素。另一方面，可植入传感器直接或间接地与身体内的生物成分（例如组织、器官或肌肉）接触，以支持或治疗身体功能或问题。随着这些先进传感器的发展，我们可以在未来与数量庞大的传感器共同生活。对于未来可以完全植入的身体传感器网络，支持传感器运行的可持续能源以及能够在体内长期使用的材料的开发仍然是挑战。在这篇综述中，我们首先总结了灵活和可穿戴平台方面的各种最先进的传感器。此外，我们回顾了最近的研究趋势的能量采集器的机械和热能转换成有用的电力的传感器的操作。此外，我们涵盖了最近的研究方面的植入式传感器的材料。最后，我们讨论了传感器的未来发展方向，可能使植入体内的身体传感器网络。(C)2019年作者。
Flexible electronics technology dramatically changes the capability of sensors, which allows us to detect human biological signals not only on the skin but also inside the human body. Wearable sensors that stick to the skin surface can detect various biomechanical movements, biological signals, and byproducts such as useful elements from sweat and body temperature. On the other hand, implantable sensors directly or indirectly contact with biological components inside the body, such as tissue, organs, or muscles, to support or treat bodily functions or problems. With the development of these advanced sensors, we can live together with a huge number of sensors in the future. Toward body sensor networks that can be fully implanted in the future, sustainable energy sources that support the operation of sensors as well as the development of materials that enable long-term use inside the body remain challenges. In this review, we first summarize various state-of-the-art sensors in terms of flexible and wearable platforms. Additionally, we review the recent research trends of energy harvesters in mechanical and thermal energy conversion into useful electricity for the operation of the sensors. Furthermore, we cover recent studies in the aspect of materials for implantable sensors. Finally, we discuss future direction of the sensors that may enable implanted body sensor networks in the body. (C) 2019 Author(s).
