Liquid-in-liquid printing of Janus constructs

Flexible and lightweight electronics are the basis of the Internet of Everything (IoE), where people, processes, data, and devices
will be integrated to change the future of mankind. Up to now, much research has been conducted on structures with
simultaneous high electrical conductivity and mechanical flexibility as the core of IoE. However, high-volume manufacturing,
reliability, and performance per cost remain elusive goals for the broad commercialization of these constructs. This project
focuses on a new 3D printing strategy called liquid-in-liquid printing. In this approach, the assembly of nanomaterials in the final
structure can be tuned to achieve higher electrical, thermal, and mechanical stability. Specifically, we want to expand the allliquid-
liquid extrusion printing of functional materials and achieve a new class of soft constructs named Janus liquid, i.e., Janus
liquid threads or Janus filaments. In this class of all liquid extrusion printing, nanoparticles with different functionalities are
heterogeneously distributed in two opposing faces of printed structures. These structures can be used for multi-modal sensing,
where nanoparticles on opposite sides respond to different stimuli.
