Abstract A new self-powered ammonia (NH3) nanosensor with flexibility, portability, good selectivity and sensitivity has been developed from conducting polyaniline nanofibers (PANI NFs) based triboelectric nanogenerator (TENG). The power supply and gas sensor have been successfully integrated into one device. The PANI NFs with NH3 sensing property work both as a frictional layer and an electrode in the TENG. The TENG shows high output performance with the maximum short current circuit of 45.70 μA and output voltage of 1186 V in air, while its output voltage is obviously reduced in varying degrees after being exposed to NH3 with different concentrations, resulting from the change of electroconductivity of PANI, which is the design principle of the NH3 sensor. Meanwhile, this NH3 nanosensor exhibits good selectivity and sensitivity with the limit detection of 500 ppm at room temperature. This work proposes a new thought to design the self-powered NH3 nanosensor, which has the widespread application prospect to harvest ambient energy for detecting toxic NH3 without any external power sources.
