“…A self-powered chemical sensing system has been built by connecting a resistance-type gas (NO 2 ) sensor with a contactseparate mode triboelectric harvester in series and an LED in parallel (Shen et al, 2018). The system worked as a vehicle exhaust detector, where the triboelectric harvester was driven by the motor vehicle exhaust flow, thus powering the gas sensor and giving an alarm via the LED.…”

Energy harvesting is one of the most rapidly growing of the emerging technologies. This field has arrived at the hybrid and multi-source era, where hybrid structures and novel materials are able to boost the energy conversion efficiency and/or make the harvesters capable of benefitting from multiple energy sources simultaneously. Such hybrid and multi-source energy harvesters have not frequently been reviewed in the past, potentially because of the small number of publications compared to that of their single-source and individual counterparts. However, as their number is becoming larger, it is now necessary to give sufficient and frequent reviews of developments in the field. Furthermore, an increasing number of developed energy harvesters are moving out of the laboratory into industrial markets. In practice, energy harvesters need to be integrated with energy storage and/or end users such as sensors and wireless sensor networks. Therefore, the harvester-storage and harvester-sensor integration systems also need to be reviewed frequently. This mini review includes works reported in the first half of 2018 and provides a timely update to the published review. It focuses on the abovementioned hybrid and multi-source energy harvesters as well as on integrated harvesters, energy storage systems and end users (e.g., sensors), including CMOS (complementary metal-oxide-semiconductor) technology-based harvesters and systems.

“…Many transduction mechanisms for energy harvesting have already been developed, and many designs of harvesting devices have been provided for a wide range of applications from small-to large-scale powering [1][2][3][4][5][6][7]. A few years ago, the interest of researchers was attracted by the triboelectric effect, by which electricity is produced due to mechanical friction between two bodies in a motion [8,9]. This triboelectric effect has been known for a long time and is thought to be purely electrostatic in binary systems [10,11].…”

“…Hence, action is urgently needed to seek effective technologies to remove airborne PMs or other pollutants. TENG has been successfully developed to realize efficient air filtering [110,172,[175][176][177] and vehicle emission treatment [173,178]. In fact, TENG-based air purification products are already available in the market [174].…”

Sensor networks are essential for the development of the Internet of Things and the smart city. A general sensor, especially a mobile sensor, has to be driven by a power unit. When considering the high mobility, wide distribution and wireless operation of the sensors, their sustainable operation remains a critical challenge owing to the limited lifetime of an energy storage unit. In 2006, Wang proposed the concept of self-powered sensors/system, which harvests ambient energy to continuously drive a sensor without the use of an external power source. Based on the piezoelectric nanogenerator (PENG) and triboelectric nanogenerator (TENG), extensive studies have focused on self-powered sensors. TENG and PENG, as effective mechanical-to-electricity energy conversion technologies, have been used not only as power sources but also as active sensing devices in many application fields, including physical sensors, wearable devices, biomedical and health care, human–machine interface, chemical and environmental monitoring, smart traffic, smart cities, robotics, and fiber and fabric sensors. In this review, we systematically summarize the progress made by TENG and PENG in those application fields. A perspective will be given about the future of self-powered sensors.
