Static marks generated by friction between dissimilar materials consist of finely mixed positive and negative charges, making 2D imaging difficult with conventional surface electrometers and causing contamination when using charged toners. To address these issues, we developed a 128-element floating extended-gate organic transistor array. In this report, we demonstrate that this device enables non-contact, non-contaminating, and quantitative evaluation of fine static marks with sub-millimeter resolution, which has been challenging to achieve with conventional methods.
