Bio


Josué García-Ávila, from Guerrero, México. He earned a Bachelor's degree in Mechatronics Engineering from Universidad Anáhuac and a Master’s degree in Manufacturing Systems at Tecnológico de Monterrey, where he was graduate student of Advanced Manufacturing Research Group. He worked in the automotive industry as a Sr. Manufacturing Engineer (Machining & Assembly) at Bocar Group during several years and lived in Costa Rica for 2 years doing humanitarian work. Now, his research interests include data-driven mechanics of architected, multifunctional, sustainable, soft, and stretchable materials to mimetic artificial living matter for biomedical applications and beyond. Josué has a couple of first-author publications and was recipient of academic scholarship by National Council of Science and Technology of Mexico (CONACyT) during his master studies. He will be pursuing a PhD's degree in Mechanical Engineering at Stanford School of Engineering and is award, by nomination of the graduate admissions committee, the EDGE Doctoral Fellowship.

    Abstract

    The strategy of embedding conductive materials on polymeric matrices has produced functional and wearable artificial electronic skin prototypes capable of transduction signals, such as pressure, force, humidity, or temperature. However, these prototypes are expensive and cover small areas. This study proposes a more affordable manufacturing strategy for manufacturing conductive layers with 6 × 6 matrix micropatterns of RTV-2 silicone rubber and Single-Walled Carbon Nanotubes (SWCNT). A novel mold with two cavities and two different micropatterns was designed and tested as a proof-of-concept using Low-Force Stereolithography-based additive manufacturing (AM). The effect SWCNT concentrations (3 wt.%, 4 wt.%, and 5 wt.%) on the mechanical properties were characterized by quasi-static axial deformation tests, which allowed them to stretch up to ~160%. The elastomeric soft material's hysteresis energy (Mullin's effect) was fitted using the Ogden-Roxburgh model and the Nelder-Mead algorithm. The assessment showed that the resulting multilayer material exhibits high flexibility and high conductivity (surface resistivity ~7.97 × 104 Ω/sq) and that robust soft tooling can be used for other devices.
