Terahertz biometric sensors for fingerprint scanning
Preprint, 2022

This study is motivated by a combination of the sustainability and vital need for enhancing authentication security
of digital devices, both personal and corporate. We present an inhouse built millimeter-wave frequency biometric sensor setup and obtained original data, measured in real-time, of both an artificial stamp and a real human fingerprint. This setup lays the ground for an intended biometric sensor for further use implementing graphene, which is foreseen to be an important two-dimensional material in future electronics and sensing applications.
