NANOTRET: Nano‐micro‐structured permanently charged surfaces for electret nanogenerators
I work in the project NANOTRET with the task to fabricate a nanostructured layer with permanently imprinted charges. Layers of this kind are called electrets and are mainly used in microphones and air filters, but more recently also in vibration energy harvesters. My work aims to develop and optimize a new class of electret layers with nanostructured charge traps. I do the optimization in terms of charge density and charge stability, to develop a reliable energy generator with relatively high power output.
