Exploring 1D and 2D Nanomaterials for Health Monitoring Wearable Devices
Abstract
In this work we explore 1D and 2D nanomaterials (carbon nanotubes and MoS2, respectively) as the core sensing components of novel sensitive and highly flexible strain sensors to monitor patients' vital signs. We assess the materials performance following a multi-disciplinary and multi-level approach, starting from atomistic simulations, up to device fabrication and applications. We successfully developed a CNT-based sensor able to detect very low strain (~2%), and with GF up to ~60 at 120% strain. We tested such sensor for the detection of the respiratory rate in living beings, and we showed that these materials are excellent candidates to be used for the development of next generation health monitoring wearable devices.
