Overview

The development of new processes and materials with extraordinary electronic and mechanical properties has inspired research in new applications in the field of wearable electronics, mobile healthcare, and cognitive functions on Internet of Things (IoT) edge systems. 

Two running h2020 FET projects are dedicated to explore these new applications and demonstrate suitable solutions.

WASP (Wearable Applications on Paper) is leveraging the capability to fabricate complete circuits integrating sensors, energy harvesters and transistors for healthcare and well-being fabricated on flexible and eco-friendly substrates such as paper, by developing a sustainable technology in terms of the energy required in the production chain and storage (embodied energy) and of total product life-cycle.

QUEFORMAL (Quantum Engineering for Machine Learning) exploits materials-to-devices-to-circuit design and fabrication of energy-efficient neuromorphic circuits capable to implement an analog neural network using transistors and non-volatile memories based on 2D Materials. The capability to tailor materials properties using vertical and lateral heterostructures of 2D materials provides a wealth of options to optimized energy efficiency in terms of operations per unit energy.

On the basis of the experience and the results obtained in WASP and QUEFORMAL, scientists from the consortium will contribute to the tutorial addressing the main issues related to both wearable applications and artificial intelligence, while leveraging the new technology based on two-dimensional materials.
