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.

Triboelectric nanogenerator (TENG) has attracted increasingly attention in a new energy field. However, it is still a huge challenge for TENG to transmit electricity or be self‐powered sensing without hard wires, which can reduce the efficiency of power generation and further cause inconvenience for connecting device. Here, a flow‐driven wireless TENG for efficient power transmission, ultrasensitive distance sensing, and obstacle monitoring in the gas pipe is reported. The wireless TENG can generate a voltage/current signal of about 121.0 V/4.4 µA at the receiving distance of 1.5 cm with a wind speed of 18.0 m s−1. When the distance is increased to 10.0 cm, the output voltage can be decreased to 8.0 V with a sensitivity of 92% owing to the decrease of induced charges on receiving electrodes. The relationship that the output voltage decreases with increasing the receiving distance has been confirmed, suggesting the possibility of the wireless TENG as a self‐powered distance sensor. Moreover, by installing several wireless TENGs uniformly in a gas pipe, the position and specific placement state of an obstacle in gas pipe can be effectively monitored with the self‐powered way.

“…Several technologies have been developed for the effective conversion of mechanical energy into electricity, including piezoelectric transducers [10][11][12], and electromagnetic induction [13][14][15]. Among these technologies, the triboelectric nanogenerator (TENG), a recently developed mechanical energy harvesting technology, has been attracting significant attention; its working principle is based on the combination of triboelectrification and electrostatic induction [16][17][18][19]. In typical TENGs, the electrode is covered with a polymer material to maximize the surface charge, after which it is placed in contactseparation with a counter-charged triboelectric material to generate electricity [20][21][22][23].…”

The triboelectric nanogenerator (TENG) is a recent mechanical energy harvesting technology that has been attracting significant attention. Its working principle involves the combination of triboelectrification and electrostatic induction. The TENG can harvest electrical energy from both solid-solid and liquid-solid contact TENGs. Due to their physical difference, triboelectric materials in the solid-solid TENG need to have high mechanical properties and the surface of the liquid-solid contact TENG should repel water. Therefore, the surface of the TENG must be versatile for applications in both solid-solid and liquid-solid contact environments. In this work, we develop a solidsolid/liquid-solid convertible TENG that has a slippery liquid-infused porous surface (SLIPS) at the top of the electrode. The SLIPS consists of a HDFS coated hierarchical Al(OH) 3 structure and fluorocarbon liquid. The convertible TENG developed in this study is capable of harvesting electricity from both solid-solid and liquid-solid contacts due to the high mechanical property of Al(OH) 3 and the water-based liquid repelling nature of the SLIPS. When the contact occurs in freestanding mode, electrical output was generated through solid-solid/liquid-solid sliding motions. The convertible TENG can harvest electricity from both solid-solid and liquid-solid contacts; thus, it can be a unified solution for TENG surface fabrication.
