Abstract: A method and apparatus for forming vascular-like channels involves liquid-in-liquid 3D printing utilizing two polymer solutions used as a printing ink and a matrix. Anionic polyacrylamide (APAM) is one of the polymer solutions and acts as the matrix material. Chitosan is the other polymer solution and acts as the printing ink. The chitosan printing ink is extruded through a print nozzle of a 3D printer onto the APAM matrix which covers the bottom of a petri dish while the nozzle is moved in a desired pattern for the channels. The chitosan and APAM polymer complexes self-assemble on the ink-matrix interface, locking chitosan polymers inside the matrix before they can spread and causing the formation of soft elastic membranous walls. The chitosan ink and APAM matrix can be removed after the polymer complex self-assembly. The printed chamber with membranous walls allows for liquid infusion to work as fluidic channels.

Abstract: An electrical power supply designed to supply electrical power to an electrical power bus is presented herein. The electrical power supply comprises an electronic controller connected to a DC/DC converter and a current sensor for measuring the converter's current. The DC/DC converter is linked to a power conductor of the electrical power bus through a first switch and to a ground conductor through a second switch. The electronic controller is programmed to manage the first and second switches, disconnecting the DC/DC converter from the power bus when the current surpasses a predetermined threshold. This innovative system ensures efficient power management and protection against overcurrent situations in electrical power supply applications.
