In this project nanocrystalline graphene (NCG) is examined as a basis for transparent strain sensors. The starting point is a theoretical work, which predicts that piezoresistivity in graphene can be increased by certain grain boundaries. Up to now, this effect is not described experimentally in the literature, but appears - according to pre-experimental results - to be existent. Combining experimental and theoretical methods the goal will be to clarify the influence of grain boundaries, functionalisation and band structure effects on piezoresistivity in NCG.

在这个项目中，纳米晶石墨烯(NCG)被检测为透明应变传感器的基础。其出发点是一项理论工作，它预测石墨烯的压阻性可以通过一定的晶界来增加。到目前为止，这种效应在文献中还没有实验描述，但根据实验前的结果，似乎是存在的。结合实验和理论方法，目标将是阐明晶界、官能化和能带结构效应对NCG压阻的影响。
