Additive Manufacturing of Customized Flexible Wearable Sensors for Sweat Analysis with Bespoke, Low-Cost Conductive TPU.

ABSTRACT: The development of wearable technology that is non-invasive, customizable, comfortable for the user, and able to transmit data to healthcare providers from remote and rural locations has the potential to revolutionize the healthcare sector and aligns with key United Nations Sustainable Development Goals. In this work, bespoke conductive filaments based on thermoplastic polyurethane (TPU) incorporating different ratios of carbon black (CB) and graphite (GRT) were developed, for the first time, via melt extrusion for additive manufacturing of flexible, wearable electrochemical sensors. Eight formulations were systematically evaluated in terms of morphology, electrical resistance, wettability, and electrochemical behavior. The hybrid composition containing 20 wt% CB and 20 wt% GRT demonstrate
