A method of forming a protective film on at least one electronic module is provided. The method includes the following steps. A protective material is disposed on at least one electronic module such that the protective material and the electronic modules are in contact with each other. The electronic modules and the protective material disposed on the electronic modules are disposed in a chamber, and a first ambient pressure is provided in the chamber. The protective material in the chamber is heated to a first temperature to soften the protective material disposed on the electronic modules. After the protective material is softened, a second ambient pressure greater than the first ambient pressure is provided in the chamber, wherein a gas in the chamber directly pressurizes the protective material such that the protective material conformally covers a top of the electronic modules. The protective material conformally covering the top of the electronic modules is heated to a second temperature to solidify the protective material conformally covering the top of the electronic modules to form a protective film conformally covering the top of the electronic modules.

The invention relates to a process of fabricating a beaded path on the surface of a substrate, the process comprising: preparing a dispersion of particles in a liquid; supplying the prepared dispersion to at least one electrically conductive microcapillary in a continuous manner; forming and maintaining a convex meniscus of the dispersion at the outlet end of the microcapillary positioned above and/or below the surface of a substrate; applying alternating voltage to the microcapillary so that a beaded structure is formed between the dispersion meniscus and the surface of the substrate; and moving the microcapillary relative to the substrate and/or the substrate relative to the microcapillary so as to deposit the particles of the formed beaded structure on the surface of the substrate and simultaneously rebuild the beaded structure formed between the dispersion meniscus and the surface of a substrate. The invention also relates to a system for realizing this process and the use of the beaded path fabricated in accordance with the process of the invention for the production of electrodes in photovoltaic cells, new generation clothing, electronic components, including flexible electronics, artificial flagella, photonic and optomechanical materials, as well as for the regeneration of damaged paths on the surface of a substrate.

Moreover, the process occurs outside a liquid environment and enables fabricating of paths in a continuous manner, that is, through the formation of the beaded structure and its simultaneous depositing on the surface of a substrate allowing the fabrication of beaded paths of arbitrary length.

Disclosed are examples for printing a one-dimensional (1D) nanomaterial for use in stretchable electronic devices. An ink comprising a nanomaterial solution is dispersed from a pneumatic dispensing system of a printing device. The 1D nanomaterial is printed in a predefined pattern on an underlying substrate positioned on a ground electrode. A voltage is applied between the printing nozzle and the ground electrode to cause the ink to form into a cone during the printing. The substrate can be modified to increase the wettability of the substrate to enhance adhesion of the ink to the substrate.
