Additive manufacturing of millimetre wave wireless sensors based on nanoparticle inks for pervasive IoT sensing and 5G communications

The implementation of wireless sensor nodes using nanomaterials at millimetre waves based on inkjet/3D printing paves the way for sensor miniaturization due to the small sensor footprint as a direct consequence of the small wavelength. Antenna based sensing techniques will be used where the presence of objects, or gases, humidity or temperature in the designed antenna environment leads to a change in its electromagnetic behaviour such as radiation pattern and input impedance characteristics which in turn result in measurable parameters for sensing applications. Such sensing techniques minimize the energy requirement of the developed sensors. The project effectively combines two timely trends for 5G communications and IoT and additive manufacturing and 3D printing of nanotechnology based matetials, and aims to reduce cost, footprint and energy requirements. There are numerous applications within the 5G and IoT framework which the results of this work can be applied including environmental sensing, asset aging and degradation due to humidity, temperature or mechanical degradation, but also communication, presence detection, through wall radar, and collision avoidance in autonomous vehicle systems.
