Design and implementation of a low-cost electrospinning setup for nanofibers fabrication

Abstract

This paper presents an advanced electrospinning device designed for novel nanomaterials production, focusing on its innovative software architecture and open-source approach. The system, built around an Arduino Mega microcontroller, utilizes FreeRTOS for efficient task management and real-time control. Developed using PlatformIO, the entire codebase is hosted in an open GitHub repository, promoting collaboration and customization. Key hardware features include a high-voltage source with precise output measurement, an LCD interface for parameter adjustment, and accurate motor control for the syringe pump. The implementation of GitHub Actions ensures cross-device compatibility and streamlines the development process. Custom-written code enhances voltage reading and motor control, adapting to various research requirements. This open-source, real-time operating system-based approach represents a significant advancement in electrospinning technology, potentially accelerating the development of new nanomaterials with tailored properties for applications in tissue engineering, filtration, energy storage etc.
