    Description: We designed a flexible robust sensor with ZnO/ZnS core-shell nanoarrays to detect Pb 2+ ions. This device is powered by electrical energy transferred from the environmental mechanical energy and senses Pb 2+ ions with the cation exchange reaction between ZnS shell and Pb 2+ ions (ZnS (s) + Pb 2+ (aq) ↔ PbS (s) + Zn 2+ (aq)). The high density intrinsic carriers in PbS diffuse into the ZnO core to partly screen the piezopotential, which results in an exponential relationship between the concentrations of Pb 2+ ions and the piezo-voltages. The detected limit is as low as 1 ppm. This sensor also exhibits a very high selectivity towards Pb 2+ ions due to the limitation of energy band and solubility, which has potential applications in environmental protection and pollutant surveillance.
