The development of prosthetic technologies plays a crucial role in addressing the needs of individuals with limb loss while also serving as a valuable educational tool in biomedical engineering. However, most existing prosthetic systems are costly, complex, and inaccessible to students or innovators who wish to explore bioelectrical signal processing and assistive device prototyping. Addressing this challenge, our team developed BioHand: Modular EMG-Controlled Prosthetic System for Education and Assistive Technology Prototyping, a wearable electromechanical solution designed to simulate hand movement using muscle signals, offering an affordable and practical platform for both education and innovation. The primary objective of BioHand is to provide a low-cost, modular system that demonstrates the principles of biosignal acquisition, embedded systems, and robotics in real time. The device integrates three essential components: an EMG (electromyography) sensor, an Arduino Uno Rev3 microcontroller, and a servo motor. The EMG sensor detects electrical impulses generated by forearm muscles, which are then processed by the Arduino Uno. Based on the intensity and pattern of these signals, the Arduino sends commands to the servo motor, enabling finger or wrist movement. This real-time feedback loop allows users to intuitively control the prosthetic-like hand through voluntary muscle activation. The novelty of BioHand lies in its modularity and adaptability. Unlike conventional prosthetic prototypes, this system can be easily expanded by adding more servo motors for individual finger control, integrating wireless modules for remote operation, or embedding machine learning algorithms for gesture recognition. This flexibility makes it not only an educational tool but also a functional prototyping platform for assistive technologies. The applicability of this innovation spans multiple contexts, including STEM classrooms, university research labs, and maker communities, where students and innovators can gain hands-on experience in coding, electronics, and human-centered design. Commercially, its affordability and scalability give it strong potential as an entry-level prosthetic prototyping kit for institutions and training centers, reducing dependence on expensive commercial prosthetic systems. The impact of BioHand is both educational and social. Economically, it provides a low-cost pathway for skill development in biomedical engineering and robotics. Socially, it raises awareness of prosthetics and rehabilitation technologies, encouraging inclusive innovation that benefits people with disabilities. With further refinement and large-scale production, BioHand holds strong commercialization potential as a teaching aid, a maker tool, and a stepping stone toward next-generation assistive technologies.
