mmWave Nano-sensor Platform: Printed Digital Biomarker
Abstract
The research objective is to investigate the mmWave wireless biosensor platform using printed digital biomarkers. Digital biomarkers are RFID-based extremely low-power, low-cost, and self-sustainable printed wireless sensor. The digital biomarkers are fabricated by printing technology that can be easily integrated with the state-of-the-art nano/bio-technologies. For example, CNTs (carbon-based gas sensing materials) or enzymes (for protein detection) can be printed on the metallic electrode to implement low-cost fully printed biosensor. The chemical/physical reactions of the nano-sensing materials printed on the electrode change electrical characteristics of the sensor in mmWave frequency range. The altered electrical characteristics modulate the input interrogation signal, and the signal is re-radiated to the interrogator. The re-radiated signal is collected and analyzed by an interrogator to detect the event. The interrogator can be any mobile device, such as a cell phone with 5G mmWave capability. The beam steering capability of mmWave mobile system enables interrogation of the biomarkers one-by-one in consecutive order.
