Abstract
Novel fingerprint scanning arrays based upon capacitance sensing have been made. Each sensor element consists of a capacitor electrode and t wo poly-Si thin film transistors for addressing and read out. The devi ces were fabricated on glass, polyimide and polyethersulphone substrat es using a low temperature (<250 degrees C) process.
