Introduction

The application of artificial intelligence (AI) in prosthetic adaptation has significantly improved the functionality, precision, and responsiveness of modern prosthetic devices [1]. Traditional prosthetic limbs often lack the capability to provide real-time sensory feedback, leading to limitations in dexterity, proprioception, and overall user experience [2]. The integration of AI-driven algorithms allows for advanced motor control, real-time adaptation, and personalized learning, ensuring that prosthetic devices can dynamically adjust to user behavior and environmental conditions [3]. By leveraging AI, prosthetics can decode neural and muscular signals with higher accuracy, enabling seamless interaction between the artificial limb and the user’s nervous system [4]. This technological advancement enhances movement precision, reduces cognitive load, and offers a more intuitive and natural user experience [5]. 

Multi-modal sensory feedback systems play a crucial role in AI-powered prosthetics, addressing the challenge of restoring sensory perception in individuals using artificial limbs [6]. The combination of electromyography (EMG) sensors, mechanoreceptors, haptic feedback actuators, and neural interfaces allows AI algorithms to interpret sensory input and deliver real-time feedback [7]. AI-driven sensory adaptation techniques refine the way prosthetic devices respond to variations in grip strength, object textures, pressure distribution, and movement patterns [8]. Haptic feedback mechanisms, integrated with AI models, further enhance the user’s ability to experience touch, thereby improving functional dexterity [9]. Deep learning-based signal processing techniques facilitate the seamless fusion of multiple sensory inputs, optimizing prosthetic control and enhancing the level of interaction between the user and their environment [10]. These advancements bridge the gap between artificial and biological limb functionality, allowing for a more natural and immersive prosthetic experience [11].
