Novel fingerprint scanning arrays using polysilicon TFT's on glass and polymer substrates

Novel fingerprint scanning arrays based upon capacitance sensing have been made. Each sensor element consists of a capacitor electrode and two poly-Si thin film transistors for addressing and read out. The devices were fabricated on glass, polyimide and polyethersulphone substrates using a low tempe...
