Personal, multifunctional, and smart electronic devices/systems are indispensable components of the internet of things for modern information collection and exchange, which play a key role in facilitating the development of human civilization. Traditional technique for powering these sensor nodes mainly relies on batteries, which may not be favorable owing to the limited battery lifetime, large sensor population, wide distribution, as well as the potential of environmental detriment. Extricated from external power sources, triboelectric nanogenerators (TENGs) based active sensors have been extensively spread into a variety of fields for self-powered high-performance sensing, featured as being lightweight, extremely cost-effective, and environmentally friendly. In this article, current progress of TENGs as smart sensors for self-powered touch detection, vibration and acoustic sensing, biomedical applications, as well as human-machine interfacing, has been comprehensively reviewed, from aspects of materials usage, device fabrication to practical applications. The latest representative achievements regarding the TENG based self-powered sensing systems were also systematically presented. In the end, some perspectives and challenges for the TENG based selfpowered smart sensors were also summarized. I. INTRODUCTION
Smart sensors are effective means to collect useful information for us from ambient environment, which is getting more and more important especially with the fast development of internet of things (IoT). Smart sensors have already penetrated into every corner of our daily life, such as industrial production, marine exploration, environmental protection, resource investigation, medical diagnosis, biological engineering, even the protection of cultural relics, and so on. It is no exaggeration to say that various sensors are indispensable to the complicated engineering systems for many modern projects, which is critical to the human economic development and social advancement.1–9 Over the past decades, various kinds of sensors for health monitoring, environmental protection, infrastructure detecting, and security have been developed.10–14 It is said that the world will have trillions of sensor cells positioned on the world by 2020.15 The recent development of IoT and sensor networks rapidly changes the Contributing Editor: Paul Muralt Address all correspondence to these authors. a) e-mail: [email protected] b) e-mail: [email protected], [email protected] DOI: 10.1557/jmr.2017.162
