▎ 摘  要

NOVELTY - Method for fabrication of piezoresistive pressure sensor for real time health-monitoring applications. The sensor fabrication comprises two steps, synthesis of hydrophilic d-reduced graphene oxide (d-rGO) ink, and employing the prepared ink for the fabrication of the sensor using dip and dry technique. USE - The method for fabrication of piezoresistive pressure sensor for real time health-monitoring applications, both small-scale motion, blood pulse response sensor through the wrist and neck pulses, throat response while speaking different word cheek response with blowing and also as large-scale motion monitoring sensors, including finger response under different bending condition. It can be employed for detecting the health of the mechanical motors such as gear-box, different pumps and any such application where it is possible to detect the difference in the vibrations or audio signals originating from the new mechanical machine with respect to old one (all claimed). ADVANTAGE - The method for fabrication of piezoresistive pressure sensor have been extensively employed due to their appealing advantages such as low-cost, feasible processing and convenient signal collection. These work on a very simple principle in which the imposed pressure is transduced to electrical signals i.e. resistance signal.
