We have substantial expertise in the solution-based synthesis of ZnO nanorod arrays for use in piezoelectric energy harvesters (nanogenerators), including on (conductive) glass, plastic, textile and fibre-based substrates. ZnO is piezoelectric, so when strained, the nanorod arrays will generate a potential difference between their two surfaces, and as such can be used for mechanical energy harvesting (mechanical to electrical). We developed a novel p-n junction based nanogenerator using a junction between ZnO nanorods and PEDOT:PSS, and have developed this to significantly increase the output voltage and power, transfer it to textile substrates for wearable applications, and investigate its commercial potential.
