Demonstration of a conductive CNT ink enhancing performance in wearable sensors, indicating innovation in flexible devices.

This research aims to improve the dispersibility and adhesiveness of carbon nanotube ink for wearable sensors.
Developed a CNT-based conductive dispersion using cellulose derivatives and γ-aminopropyl triethoxy silane as a cross-linking agent.
Fabricated textile-based strain sensors through stencil printing and sponge-based pressure sensors via dipping method.
Encapsulated strain sensors with polydimethylsiloxane to enhance durability and working range.
Textile strain sensors expanded working ranges from less than 20% to nearly 70%, demonstrating prompt responsiveness to stimuli.
Sensors effectively monitored human motions such as finger folding and wrist bending, showcasing exceptional performance.
Sponge sensors exhibited high sensitivity and excellent durability, confirming the versatility of the conductive ink.
