| Abstract Scope |
Development of wearable electronics with biological sensors has emerged as a significant area of focus in additive manufacturing. However, current methods pose a substantial ecological footprint. To address this issue, it is imperative to explore diverse additive manufacturing techniques, among which aerosol jet printing (AJP) is a prominent candidate. AJP requires the optimization of variables such as gas flow rates and ink rheology to achieve high-resolution printed structures. Notably, MXenes demonstrate the mitigation of ecological footprint while enhancing device functionality. This work demonstrates the synthesis of titanium carbide MXene using the minimally intensive layered delamination method. Resultant nanoparticles are characterized and formulated to an ink compatible with AJP. Experimental synthesis of such ink yields a viscosity of 3.5 cP, surface tension of 45 mN/m, density of 1055 kg/m3, and a contact angle of approximately 58º when printed onto a Kapton substrate. MXene inks are then used to print wearable biosensors. |
