Assessment of 1D and 2D Materials for Health Monitoring Wearable Devices

National audience; Here, the performance of 1D and 2D nanomaterials (carbon nanotubes and MoS2, respectively) was assessed for the development of novel highly sensitive and flexible strain sensors to monitor patients’ respiratory rate. To do so, we followed a multi-disciplinary and multi-level ap- proach, starting from atomistic simulations, up to device fabrication and ex-vivo testing. We successfully designed, fabricated and tested a CNT-based flexible strain sensor capable of tracking the respiratory rate, and we showed 1D and 2D materials to have excellent mechanical and electronic properties for the use in such devices.
