ENHANCING SENSITIVITY BY DIRECTLY PRINTING NANOSENSORS USING ADVANCED MANUFACTURING TECHNIQUES ON A PRE-AMP BOARD OR A DAUGHTERBOARD

摘要

The present invention provides a printable nanosensor and leads that can be manufactured using three-dimensional printing techniques and printing directly on a daughter board that can be connected to a self-contained pre-amplified printed circuit board. Although graphene is highly sensitive as a chemical sensor and can detect parts per million (ppm) concentrations of species, the integration of printed graphene and other two-dimensional sensing materials to form a sensor assembly can be used to increase the sensitivity even further, enabling detection of parts per billion (ppb) concentrations and even single molecule detection.
