Polymer Thick-Film Sensors: Possibilities For Smartcard Biometrics [PDF]

, 2018
The potential of polymer thick-film sensors are assessed for use as biometric sensors on smartcards. Piezoelectric and piezo-resistive sensors have been printed on flexible polyester, then bonded to smartcard blanks. The tactile interaction of a person with these sensors has been investigated.
