Static electricity is known to cause various problems such as breakdown of electronic devices, dust adhesion, fogging in vacuum deposition, and coating defects. In particular, static marks are a complex mixture of positive and negative static electricity and can be produced by electrostatic or corona discharge. Since the net charge is close to zero, such static marks are difficult to detect and remove with conventional equipment. Currently, the detection of the static marks requires a special toner, which contaminates the objects. Here we show a contamination-free and non-contact electricity imaging system based on a floating extended-gate organic field-effect transistor array.
