We explore a type piezoelectric material 0.9525(K0.5Na0.5NbO3)-0.0475LiTaO(3) (KNN-LTS) which can be used to fabricate nanogenerator with high output voltage and current due to its high piezoelectric constant (d(33)). Because of its unique structure mixed with multi-wall carbon nanotube and polydimethylsiloxane, the output voltage is up to 53 V and the output current is up to 15 uA (current density of 12.5 uA/cm(2)) respectively. The value of the output voltage and output current represent the highest level in the piezoelectric field reported to date. The KNN-LTS nanopowder-based nanogenerator can also be used as a sensitive motion detection sensor. (C) 2015 Author(s).
